SECTION: 4.20 is for some information and illustrations relating to example images of the various Display Modes that affect the way drawing elements are displayed.

The Perspective Display Modes relate to the way the lines and edges of the triangle elements are colored in and outlined. The Perspective Display Modes also control how line elements, triangle elements, or mixed elements will be processed for display.

See Section: 3.1.25.0 for a detailed discussion of issues relating to Perspective Display Modes, Printing Display Modes, and other issues related to this Section.

The Stereoscopic Display Modes relate to the way the right and left eye views will be formatted for display. Different stereoscopic viewing methods require different formatting of the two images, these formatting options are controlled through a code number. Various other values are associated with each formatting code number so as to optimize the display for each Stereoscopic Display Mode, and its relation to the particular elements being displayed. The Perspective Display Mode selected affects the appearance of the images used for the Stereoscopic Display Formatting, i.e. you can use all of the Perspective Display Modes with any of the Stereoscopic Display Modes giving a large variety of combinations, only some of which would be of interest generally.

See Section: 3.3.7.8 for a detailed discussion of issues relating to Stereoscopic Viewing Methods, Anaglyph glasses, and other issues related to this Section.

The modes available and the images they produce may be altered in other program revisions, so the images generated by the program version you have may not match the illustrations shown here. Variations in the code used in different program, revisions and versions can affect the results, so you should not expect the same results from different versions and revisions of the programs. The Author reserves the right to make any kind of changes at any time without notice.

Some Browsers may not display the larger size illustrations properly, so you may only be able to view the smaller sizes of each illustration. You should turn off the shrink-to-fit feature in your browser, if it has one, since that can distort or degrade the illustrations or make thin lines disappear.

Non-Anaglyph Stereoscopic Display Modes are those that are generally viewed without colored filter glasses, see Section: 4.20.52.0 for information and examples of the Anaglyph Stereoscopic Display Modes.

Stereoscopic Perspective Display Modes are a series of code numbers that tell the CAD programs to generate two slightly different views of the same elements such that one of the two views is from the left eye's point of view and the other view is from the right eye's point of view. These two view images are then formatted in particular ways to suit various stereoscopic image viewing methods, e.g. cross-eyed viewing, anaglyph colored glasses viewing, shutter glasses viewing, and viewing with various kinds of stereoscopic viewer or viewing aid.

The various Perspective Display Modes can be used in combination with the various Stereoscopic Display Modes to generate a wide variety of 3D image formats. The Stereoscopic images so formatted can also be printed out for viewing from printed images, rather than off of the computer's screen. Stereoscopic images can also be saved as BMP image files for conversion to JPG and display on the internet, and such.

Stereoscopic Display Mode 0 is for a monoscopic view, and is the same as not using the stereoscopic option, i.e. a null command option.

BMP images taken from a Scanner or Digital Camera can be processed into similar Stereoscopic formatted images by using the [F]iles [U]tilities [B]MP [C]ombine command.

When using the BMP graphics mode keyword the stereoscopic formatting of the output may be different from the formatting used for display on the computer monitor since black padding would not be needed at the top and bottom of the screen for Stereoscopic Display Modes that format the side-by-side images.

Stereoscopic image formatting goes back more than one hundred years and so is generally well know and understood. Various stereoscopic methods have been patented over the years. Whether any patents, valid or not, affect the use of any particular Stereoscopic image format in any given country is something you should be aware of, particularly if you are going to make commercial use of a patented format, and may need to make license payments. Information about supported stereoscopic formats presented does not imply that they may be used for all purposes in all countries license free. License fees should be paid to the respective patent holders involved or as appropriate.

Stereoscopic Display Mode 1 is for making just the Right Eye View. This would be used when you want to make separate right and left images for use in a viewer that takes separate images, such as a beam splitter/condenser viewer, or using two projectors.

Stereoscopic Display Mode 1 is different than using Stereoscopic Display Mode 0 in that the special stereoscopic command options are available to enhance and control the image for use in a stereo pair.

See also Stereoscopic Display Mode 2 to make the Left Eye View.

Stereoscopic Display Mode 2 is for making just the Left Eye View. This would be used when you want to make separate right and left images for use in a viewer that takes separate images, such as a beam splitter/condenser viewer, or using two projectors.

Stereoscopic Display Mode 2 is different than using Stereoscopic Display Mode 0 in that the special stereoscopic command options are available to enhance and control the image for use in a stereo pair.

See also Stereoscopic Display Mode 1 to make the Right Eye View.

Stereoscopic Display Mode 10 is for making side-by-side formatting with the Left Eye View on the Left and Right Eye View on the Right, sometimes called Parallel or Wall- Eye stereo pair. This would be used when you want to use twin magnifier viewing aids to view printout that has the two images sized to have analogous points equal to or slightly closer than the distance between your two eyes pupils, e.g. about 60mm to 90mm. If you want to view a Parallel stereo pair that is on the computer screen or on printout larger than the spacing of your eyes, you can use a double periscope type viewing aid using front surface mirrors or 90 degree reflective prisms, or a Wedge Prism type viewer using refractive prisms.

Stereoscopic Display Mode 10 is different than using Stereoscopic Display Modes 11 and 12 only when the image is output to a BMP file by using the BMP graphics keyword, rather than direct display to the computer monitor. BMP images made using Stereoscopic Display Mode 10 lack the black padding at the top and bottom of the screen, and thus generally look better for conversion to JPG and display in Web pages or for use in making print out of the BMP file to conserve ink.

See also Stereoscopic Display Modes 11 and 12 to make the BMP images that are padded on the top and bottom with black for conversion to Pixel files.

Stereoscopic Display Mode 11 and 12 are for making side-by- side formatting with the Left Eye View on the Left and Right Eye View on the Right, sometimes called Parallel or Wall-Eye stereo pair. The difference between Stereoscopic Display Mode 10 and Stereoscopic Display Modes 11 and 12 is that when the stereo image is output to a BMP file by using the BMP graphics mode keyword the top and bottom of the image are padded with black, so that the BMP image might be later converted to a Pixel file for display with the ANIMATE or LOAD PIXEL commands.

With some video modes the aspect ratio of the black padding added by Stereoscopic Display Mode 11 does not match the pixel ratio of that video mode, so Stereoscopic Display Mode 12 is also available to make adjustments to the black padding so that conversion to Pixel from BMP will work better for those video modes. In most instances Stereoscopic Display Mode 11 and Stereoscopic Display Mode 12 do the same thing.

Stereoscopic Display Mode 10 is different than using Stereoscopic Display Modes 11 and 12 only when the image is output to a BMP file by using the BMP graphics keyword, rather than direct display to the computer monitor. BMP images made using Stereoscopic Display Mode 10 lack the black padding at the top and bottom of the screen, and thus generally look better for conversion to JPG and display in Web pages or for use in making print out of the BMP file to conserve ink.

See also Stereoscopic Display Mode 10 for some information about viewing images made with Stereoscopic Display Modes 10, 11, and 12 since they are viewed by using the same methods.

Stereoscopic Display Mode 20 is for making anamorphic side-by- side formatting with the Left Eye View on the Left and Right Eye View on the Right, sometimes called Parallel or Wall-Eye stereo pair. This would be used when you want to use an anamorphic projection lens and front surface mirrors to make 3D motion pictures that project using the anamorphic side-by-side method.

Padding is not required since the images are stretched to fit the video screen size. You may be able to adjust the anamorphic ratio by using the video aspect adjustment in the main menu Change command. If you make large adjustments to the video aspect you may be able to use this as a non-scope format with tall image windows.

See also Stereoscopic Display Mode 40 for making a stereoscopic wide screen movie that can be "free viewed" off the movie screen with crossed eyes. Stereoscopic Display Mode 40 may also be useful for projection with a different arrangement of the front surface mirrors in front of the anamorphic projection lens.

Stereoscopic Display Mode 30 is for making crossed eyes stereo pair formatted images with the Left Eye View on the Right and Right Eye View on the Left. This stereo image format is for "free viewing" with your eyes crossed. No viewing aid is needed my many people for viewing "crossed eyes" stereo pairs, and the images can be stereo viewed directly off of the computer monitor or print out. Viewing aids such as polarizing filters and polarized glasses can be used to help people view this format who have difficulty free viewing. A piece of cardboard with a rectangular hole cut in it can also be a help, the opening being held about halfway between the viewer and the computer monitor or printout so as to hide the two side images and just show the central stereo 3D image.

Stereoscopic Display Mode 30 is different than using Stereoscopic Display Modes 31 and 32 only when the image is output to a BMP file by using the BMP graphics keyword, rather than direct display to the computer monitor. BMP images made using Stereoscopic Display Mode 30 lack the black padding at the top and bottom of the screen, and thus generally look better for conversion to JPG and display in Web pages or for use in making print out of the BMP file to conserve ink.

See also Stereoscopic Display Modes 31 and 32 to make the BMP images that are padded on the top and bottom with black for conversion to Pixel files.

Stereoscopic Display Modes 31 and 32 are for making crossed eyes stereo pair formatted images with the Left Eye View on the Right and Right Eye View on the Left. The difference between Stereoscopic Display Mode 30 and Stereoscopic Display Mode 31 and 32 is that when the stereo image is output to a BMP file by using the BMP graphics mode keyword the top and bottom of the image are padded with black, so that the BMP image might be later converted to a Pixel file for display with the ANIMATE or LOAD PIXEL commands.

Stereoscopic Display Mode 40 is for making crossed anamorphic side-by-side stereoscopic images formatted with the Left Eye View on the Right and Right Eye View on the Left. This would be used when you want to use an anamorphic projection lens and "free view" the crossed eyes images on a wide screen. Stereoscopic Display Mode 40 might also be useful for using a different arrangement of surface mirrors to make 3D motion pictures that project using the anamorphic reversed side-by-side method.

Padding is not required since the images are stretched to fit the video screen size. You may be able to adjust the anamorphic ratio by using the video aspect adjustment in the main menu Change command. If you make large adjustments to the video aspect you may be able to use this as a non-scope format with crossed tall image windows.

See also Stereoscopic Display Mode 20 for making a stereoscopic wide screen movie that can be viewed off the movie screen with polarized glasses by means of projection with a different arrangement of the front surface mirrors in front of the anamorphic projection lens.

Stereoscopic Display Mode 80 is for making mirror image side-by-side formatted images with the Left Eye View on the Left and Mirror Image Right Eye View on the Right. This would be used when you want to use certain kinds of mirror or reflective prism viewers, and need the right eye view to be a mirror image, i.e. flipped side- to-side.

Stereoscopic Display Mode 80 is different than using Stereoscopic Display Modes 81 and 82 only when the image is output to a BMP file by using the BMP graphics keyword, rather than direct display to the computer monitor. BMP images made using Stereoscopic Display Mode 80 lack the black padding at the top and bottom of the screen, and thus generally look better for conversion to JPG and display in Web pages or for use in making print out of the BMP file to conserve ink.

Using the right eye and left eye reverse option may allow the formatting of crossed eye mirror right images.

See also Stereoscopic Display Modes 81 and 82 to make the BMP images that are padded on the top and bottom with black for conversion to Pixel files.

Stereoscopic Display Mode 81 and 82 are for making mirror image side-by-side formatted images with the Left Eye View on the Left and Mirror Image Right Eye View on the Right. The difference between Stereoscopic Display Mode 80 and Stereoscopic Display Modes 81 and 82 is that when the stereo image is output to a BMP file by using the BMP graphics mode keyword the top and bottom of the image are padded with black, so that the BMP image might be later converted to a Pixel file for display with the ANIMATE or LOAD PIXEL commands.

Stereoscopic Display Mode 90 is for making mirror image side-by-side formatted images with the Mirror Image Left Eye View on the Left and Right Eye View on the Right. This would be used when you want to use certain kinds of mirror or reflective prism viewers, and need the left eye view to be a mirror image, i.e. flipped side-to- side.

Stereoscopic Display Mode 90 is different than using Stereoscopic Display Modes 91 and 92 only when the image is output to a BMP file by using the BMP graphics keyword, rather than direct display to the computer monitor. BMP images made using Stereoscopic Display Mode 90 lack the black padding at the top and bottom of the screen, and thus generally look better for conversion to JPG and display in Web pages or for use in making print out of the BMP file to conserve ink.

Stereoscopic Display Mode 100 is for making over-under or above-below stereo pairs with the Left Eye View on the Bottom and Right Eye View on the Top. The eye reverse option may be able to be used to put the left eye view on the top and the right eye view on the bottom. This would be used when you want to use certain kinds of mirror or reflective prism viewers or projectors, and need the images stacked.

Stereoscopic Display Mode 100 is different than using Stereoscopic Display Modes 101 and 102 only when the image is output to a BMP file by using the BMP graphics keyword, rather than direct display to the computer monitor. BMP images made using Stereoscopic Display Mode 90 lack the black padding at the right side and left side for the screen, and thus generally look better for conversion to JPG and display in Web pages or for use in making print out of the BMP file to conserve ink.

See also Stereoscopic Display Modes 101 and 102 to make the BMP images that are padded on the sides with black for conversion to Pixel files.

Stereoscopic Display Mode 101 and 102 are for making over- under or above-below stereo pairs with the Left Eye View on the Bottom and Right Eye View on the Top. The eye reverse option may be able to be used to put the left eye view on the top and the right eye view on the bottom.

The difference between Stereoscopic Display Mode 100 and Stereoscopic Display Modes 101 and 102 is that when the stereo image is output to a BMP file by using the BMP graphics mode keyword the left and right sides of the image are padded with black, so that the BMP image might be later converted to a Pixel file for display with the ANIMATE or LOAD PIXEL commands.

Using the right eye and left eye reverse option may allow the formatting of left on top images.

See also Stereoscopic Display Mode 100 for some information about viewing images made with Stereoscopic Display Modes 100, 101, and 102 since they are viewed by using the same methods.

Stereoscopic Display Mode 120 is for making anamorphic image over-under or above-below stereo pairs with Left Eye View on the Bottom and Right Eye View on the Top. The eye reverse option may be able to be used to put the left eye view on the top and the right eye view on the bottom. This would be used when you want to use certain kinds of mirror arrangements on anamorphic projectors, and there is a need for the anamorphic images to be stacked in over- under format for wide screen 3D stereoscopic motion pictures.

Stereoscopic Display Mode 120 is different than using Stereoscopic Display Mode 121 in that Stereoscopic Display Mode 121 has an option for putting an adjustable black strip in the center between the two above-below images. The purpose of this black strip is to compensate for the vertical fly-back time in the monitor thereby allowing the two eye views to be superimposed during viewing with shutter glasses. In other words, the black strip is made high enough to have the downward travel of the electron beam in the CRT take as much time from the bottom of the top image to the top of the bottom image as the fly-back time took to go from the bottom of the bottom image to get to the top of the top image. Since the beam flys-back faster than it goes down, the black strip generally needs to be less than a third of the screen height, but the exact amount depends on the particular video board, video mode, and monitor being used. Use Stereoscopic Display Mode 121 rather than Stereoscopic Display Mode 120 for Sync Double stereo viewing.

See also Stereoscopic Display Mode 121 to make the BMP images that are padded in the center with black for display in Sync Double mode on Shutter Glasses.

The anamorphic over-under stereoscopic format becomes a non-wide- screen stereo image format when unsqueezed vertically by the 'scope projection lens. If the video aspect adjustment is used to squeeze the images horizontally to cancel out the vertical compression, the wide screen stereo images might be projected using non-anamorphic "flat" projection lenses, i.e. wide screen over-under half frame stereo images.

Stereoscopic Display Mode 121 is for making special anamorphic image over-under or above-below stereo pairs with Left Eye View on the Bottom and Right Eye View on the Top for use with Sync Double stereoscopic shutter glasses mode. The eye reverse option may be able to be used to put the left eye view on the top and the right eye view on the bottom, although the shutter glasses controller box may have a button the reverses the views without having to reverse the views on the screen. This mode would be used when you want to use stereoscopic shutter glasses in sync double stereoscopic viewing mode.

Stereoscopic Display Mode 121 is different than using Stereoscopic Display Mode 120 in that Stereoscopic Display Mode 121 has an option for putting an adjustable black strip in the center between the two above-below images. The purpose of this black strip is to compensate for the vertical fly-back time in the monitor thereby allowing the two eye views to be superimposed during viewing with shutter glasses. In other words, the black strip is made high enough to have the downward travel of the electron beam in the CRT take as much time from the bottom of the top image to the top of the bottom image as the fly-back time took to go from the bottom of the bottom image to get to the top of the top image. Since the beam flys-back faster than it goes down, the black strip generally needs to be less than a third of the screen height, but the exact amount depends on the particular video board, video mode, and monitor being used. Use Stereoscopic Display Mode 121 rather than Stereoscopic Display Mode 120 for Sync Double stereo viewing.

The goal in adjusting the center black band is to have both eye images line up on vertically analogous points. It may not be possible to get exact alignment, but you should try to get within one scan line if you can, depending on what the shutter glasses controller will let you do at a given video scan rate. Some video modes might work better than others. Since the vertical sweep rate is doubled the flicker is reduced in the shutter glasses, but your video monitor may not be able to sweep at double rate in some video modes. You may be able to adjust the video board refresh rate in the video driver board's driver setup, so as to reduce the refresh when you are using sync double mode to not over run your monitor's capabilities.

Images formatted for sync double stereo mode are not transportable to other incompatible systems, since the sync adjustment is in the image itself. When you need to post images for display to shutter glasses the interlaced stereo format may be a better choice, since no sync adjustments are required in the interlaced image when the shutter glasses controller has an eye reverse button. Interlaced images may develop problems when compressed to compressed image file types if the compression blurs the image vertically, i.e. between the interlaced images. My programs save the stereo images to BMP file format which is not compressed, and might not degrade the stereo image formatting.

Stereoscopic Display Mode 160 is for making special Interlaced stereoscopic images with Left Eye View on the even scan lined and Right Eye View on the odd scan lines for use with Interlaced, Interleaved, and Line Blank stereoscopic shutter glasses mode. The eye reverse option may be able to be used to put the left eye view on the odd scan lines and the right eye view on the even scan lines, although the shutter glasses controller box may have a button the reverses the views without having to reverse the view's lines on the screen. This mode would be used when you want to use stereoscopic shutter glasses in interlace, interleave, or line blank stereoscopic viewing modes.

The shutter glasses controller must be set to Interlace/Interleave mode when the video board is operating the monitor in interlace video mode, and to line blank shutter glasses mode when the video board is operating the monitor in non- interlace video mode. Line Blank stereo controller mode simulates interlace mode on the monitor by turning off every other scan line on alternating video fields, i.e. on field one the even scan lines are blacked out, and on field two the odd scan lines are blacked out, in this way when an interlaced image is shown on the screen every other field on the monitor is right then left eye view. If your shutter glasses controller does not have manual control, you may need to save the interlaced stereo images as a BMP file and look at them from inside some Windows (tm) graphics program.

Images formatted for sync double stereo display mode 121 are not transportable to other incompatible systems, since the sync adjustment is in the image itself. When you need to post images for display to shutter glasses the interlaced stereo format may be a better choice, since no sync adjustments are required in the interlaced image when the shutter glasses controller has an eye reverse button. Interlaced images may develop problems when compressed to compressed image file types if the compression blurs the image vertically, i.e. between the interlaced images. My programs save the stereo images to BMP file format which is not compressed, and might not degrade the stereo image formatting.

Stereoscopic Display Mode 170 is for making special Lenticular stereoscopic images with Left Eye View on the even pixel columns and Right Eye View on the odd pixel columns for use with Lenticular 3D stereoscopic flat screen monitors, and Lenticular or vertical slit array parallax barrier viewing aids. The eye reverse option may be able to be used to put the left eye view on the odd pixel columns and the right eye view on the even pixel columns, although just moving your head sideways may reverse the views without having to reverse the view's pixel columns on the screen. Special flat screen computer monitors are manufactured with vertical lenticular cylinder lenses over their face for viewing this type of stereoscopic image format in 3D without having to view through special glasses.

If you have a flat screen monitor, e.g. LCD, you may be able to fit a lenticular lens plate or parallax barrier over it to view Lenticular stereo images.

Lenticular stereo images may develop problems when compressed to compressed image file types if the compression blurs the image horizontally, i.e. between the image pixel columns. My programs save the stereo images to BMP file format which is not compressed, and might not degrade the stereo image formatting.
