Use this to output a QuickTime movie of the animation.
Use this option to output a each of the frames of the animation as a single PICT file.
Adaptive: recursively sub- divides pixels into 4 subpixels if a large color change is detected between neighboring (sub)pixels. Recursion stops when difference is too small to notice(See Aliasing Threshold).

Semi-adaptive: supersampling
subdivides pixel into the number of subpixels set by the "Supersampling" menu if a large color change is detected between pixels (See Aliasing Threshold).
Semi-adaptive: supersampling
subdivides pixel into the number of subpixels set by the "Supersampling" menu if a large color change is detected between pixels (See Aliasing Threshold).
Subpixel: supersampling sub- divides every pixel into the number of subpixels set by the "Supersampling" menu item.
(Even if that pixels' neighbors have close to the same color).

Only copy and Preferences may
be used for the Edit menu.
Edit menu allows you to copy the image to the clipboard, or to change the preferences for RTrace.
This option is gray because it does not work.
This option copies the image to the clipboard. This is only available if you have 32-bit QuickDraw. If you do not have 32-bit QuickDraw, you should use the Save Image command to save the image
This option is grey because it is inactive. If you have 32-bit QuickDraw, then after you create an image it will allow you to copy the image to the clipboard.

This option brings up the Preferences Window which allows you to set options which will carry over from session to session.
Load .sff files,
save image or QuickTime
movies.
The File menu is used to load in the scene data in .sff files and to allow you to save the pictures and animations that you make. You can also quit the program from this menu.
This prompts you for a scene description file (a text file ending in .sff). Use this when you want to tell RTrace which scene to work with.
Save image: allows you to save the image which RTrace has generated to a file. This gives you the choice of saving the image as a PICT file or as a PPM file. You will usually want to
have a PICT file on the Mac.
This item is grey because
it is inactive. After you create a rendering or animation, you can use this menu item to save it to a PICT file or a QuickTime movie.
When you choose this option, RTrace aborts any render in progress and quits.
PICT format is best for images that will be used on the Macintosh.
PPM format is a raw data format that is used to transfer image files to other systems.
Only objects which touch the corners and centers of pixels will be tested at each sub- division when using "Adaptive" or "Semi-adaptive" antialiasing. This saves time since all objects won't be re-tested so much.

All objects will be tested for antialiasing at every subpixel. Works only when using "Adaptive" or "Semi-adaptive" antialiasing. This is slower but if objects are smaller than a pixel this will help image them.

This controls the generation of shadow rays through non- opaque objects. None- means that translucent objects will not be as realistic. If a scene has translucent objects, use the full or partial options.

Corrects the direction of surface normals so that they always point toward the incident ray.

Reverses the direction of surface normals so that they point towards the incident ray
inside objects. This only matters if you have concave (hollow) or transparent objects so that you can see the interiors

This option allows you to create views for stereoscopic vision.
This eye separation distance is (actual) - the eye separation is specified in actual model coordinates
This item is gray because it is inactive. To turn it on, select a "View:Right eye" or "Left eye" from the menu.

This option allows you to create views for stereoscopic vision.
This eye separation distance is specified as a (% dist) - a percentage of the gaze distance from the Look-at point to the eye point.
