- The RTrace Textures directory contains SFF files which each render a single
- sphere with a different texture on each one. To get RTrace to render the textures,
- select the Options dialog: "Texture: Inside Objects Field" otherwise, you
- will just see a blank sphere.
-
- The .sff files in this directory were created from the .scn files using the
- program “scntosff” on a Unix machine. You can look at the .sff files with a
- text editor to see how they were derived from the .scn files.
-
- PPM is a simple image format used by the Unix program PBMPlus. It is basically
- a "raw" image format with an ASCII header and 24 bit RGB pixels with no packing or
- run-length encoding. Note that the image texture mapping files: image.sff
- and image1.sff can only open the image map once in a session and it must be
- in PPM format. The next Mac-RTrace version will allow texture mapping
- multiple images and support for texture mapping PICT format images.
-
- The colormap files such as “Rainbow.map” or “Random.map” used in many of
- the textures are just 256 ASCII triplets of RGB values.
