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.

Anaglyph Stereoscopic Display Modes are those that are viewed with colored filter glasses, see Section: 4.20.51.0 for information on, and examples of, the Non-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. Padding is used in some of the non-anaglyph stereoscopic formatting modes.

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 205 is for making monochrome Red-Cyan Anaglyph stereoscopic images with the Left Eye View as Red and Right Eye View as Cyan for use with Red-Cyan Anaglyph glasses. The eye reverse option may be able to be used to make the left eye view cyan and the right eye view red, if you have glasses that have the colored filters in that placement.

The success of Anaglyph viewing depends very much on the quality of the viewing filters in the two color eye glasses and the purity of the colors from the monitor's phosphors or filters to spectrally isolate the views to the two eyes. If the filters in the Anaglyph viewing glasses and the light from the screen are not of pure color, some of the other eye's image will be seen as a Ghost image making it hard to fuse the stereoscopic perception. 3D Anaglyph glasses sold commercially may not have filters that are strong enough to reduce ghosting to an acceptable level for viewing computer graphics, so you may need to stack more than one pair of glasses or affix extra filters onto the Anaglyph glasses to get usable results.

See Section: 3.3.7.8 for a detailed discussion of issues relating to Anaglyph glasses and colored filters, including the possible use of Neodymium and Praseodymium or Didymium rare earth glass filters.

For viewing Wire-Frame elements with Anaglyph stereoscopic formatting the Ghost Masking option values may be of use in reducing ghosting in the stereo images, but they are not a fix all for glasses with really poor saturation filters.

Stereoscopic Display Mode 206 is for making monochrome Yellow-Blue Anaglyph stereoscopic images with the Left Eye View as Yellow and Right Eye View as Blue for use with Yellow-Blue Anaglyph glasses. The eye reverse option may be able to be used to make the left eye view Blue and the right eye view Yellow, if you have glasses that have the colored filters in that placement.

See the comments above regarding Stereoscopic Display Mode 205 pertaining to Anaglyph viewing glasses and Ghost Masking, and also read Section: 3.3.7.8 for a detailed discussion of issues relating to Anaglyph glasses.

Stereoscopic Display Mode 207 is for making monochrome Magenta- Green Anaglyph stereoscopic images with the Left Eye View as Magenta and Right Eye View as Green for use with Magenta-Green Anaglyph glasses. The eye reverse option may be able to be used to make the left eye view Green and the right eye view Magenta, if you have glasses that have the colored filters in that placement.

See the comments above regarding Stereoscopic Display Mode 205 pertaining to Anaglyph viewing glasses and Ghost Masking, and also read Section: 3.3.7.8 for a detailed discussion of issues relating to Anaglyph glasses.

Stereoscopic Display Mode 208 is for making monochrome Red-Blue Anaglyph stereoscopic images with the Left Eye View as Red and Right Eye View as Blue for use with the Red-Blue Anaglyph glasses. The eye reverse option may be able to be used to make the left eye view Blue and the right eye view Red, if you have glasses that have the colored filters in that placement.

Red-Blue Anaglyph generally gives the least ghosting, but you should watch out for red filters that transmit some blue, and blue filters that transmit some red. The Red filter should be combined with strong yellow or amber filters, and the blue filter should be combined with Cyan and Blue-Green filters to cut cross transmission of the stereo images.

See the comments above regarding Stereoscopic Display Mode 205 pertaining to Anaglyph viewing glasses and Ghost Masking, and also read Section: 3.3.7.8 for a detailed discussion of issues relating to Anaglyph glasses.

Stereoscopic Display Mode 209 is for making monochrome Red-Green Anaglyph stereoscopic images with the Left Eye View as Red and Right Eye View as Green for use with Red-Green Anaglyph glasses. The eye reverse option may be able to be used to make the left eye view Green and the right eye view Red, if you have glasses that have the colored filters in that placement.

Red-Green Anaglyph can sometimes work better with printed drawings than Red-Blue because of the color absorption of some inks, but you can try both Red-Blue and Red-Green to see which has the best effect in your situation. Putting a Magenta filter over the Red filter may cut some of the Green transmission, and putting a Cyan filter over the Green filter may cut some of the Red transmission.

See the comments above regarding Stereoscopic Display Mode 205 pertaining to Anaglyph viewing glasses and Ghost Masking, and also read Section: 3.3.7.8 for a detailed discussion of issues relating to Anaglyph glasses.

Stereoscopic Display Mode 210 is for making monochrome Green-Blue Anaglyph stereoscopic images with the Left Eye View as Green and Right Eye View as Blue for use with Green-Blue Anaglyph glasses. The eye reverse option may be able to be used to make the left eye view Blue and the right eye view Green, if you have glasses that have the colored filters in that placement.

The filters for viewing Green-Blue Anaglyph can be hard to get pure enough to reduce ghosting, but by putting Yellow and Cyan filters over the Green filter, and Magenta and Cyan filters over the Blue filter you may help reduce the brightness of the ghosts.

See the comments above regarding Stereoscopic Display Mode 205 pertaining to Anaglyph viewing glasses and Ghost Masking, and also read Section: 3.3.7.8 for a detailed discussion of issues relating to Anaglyph glasses.

Stereoscopic Display Mode 225 is for making "half-color" Red-Cyan Anaglyph stereoscopic images with the Left Eye View as Red and Right Eye View as Cyan for use with Red-Cyan Anaglyph glasses. The eye reverse option may be able to be used to make the left eye view Cyan and the right eye view Red, if you have glasses that have the colored filters in that placement.

The "half-color" format mixes some color information with the monochrome anaglyph to give an image that gives muted colors in a stereoscopic image. Stereoscopic Display Mode 235 gives "full color" but may "twinkle" if objects in the image are bright or saturated colors, so the "half-color" formatting may be easier on the eyes for prolonged viewing or just give a more pleasing result, you can pick the one that works best for you.
