- For those who have a 386+387 (or 486) machine it is now possible to
- produce images with a good level of realism.
-
- Installation is:
-
- 0. Define a variable GO32 if you don't have a 387
- dos> set GO32=ansi emu DRIVE:PATH\emu387
- or if you have (or in case of a 486)
- dos> set GO32=ansi
-
- The steps to follow to create images are:
-
- 1. Create using a text editor a file with the scene description
- (view point, lights, objects, etc).
- Look at the .scn files for an example; the format description
- is in the file scn2sff.doc.
-
- CPP (or M4) macros and so on can be used...
-
- 2. Next, process the .scn file (let's suppose it is called demo.scn)
- using CPP (or M4) and then by SCN2SFF converter, to obtain the
- input file for the ray-tracer program (demo.sff).
-
- Example:
- dos> cpp -P demo.scn | scn2sff - > demo.sff
-
- 3. Run RTRACE with chosen arguments (look in rtrace.doc).
-
- Example:
- [Resolution 256x256, no antialiasing, with textures, verbose]
- dos> rtrace w256 t1 V3 demo.sff demo.pic >demo.log
-
- Wait a moment... Done.
-
- 4. To view the image (file demo.pic), it is necessary to convert it to
- a standard format like GIF or any other.
- Use the PIC2RAW program to convert to input file for shareware
- program ALCHEMY (demo.raw).
- Or convert with PIC2RGB to a raw format that PICLAB understands
- and do the manipulation with this program (very good).
-
- Example:
- dos> pic2raw demo
-
- With ALCHEMY it is possible to convert to many other formats
- (GIF, Targa, PCX, etc).
- It is also possible to view in a VGA card with ALCHEMY.
- To display, use ALCHEMY, PICLAB, CSHOW or others...
-
-
- There are many .scn and .sff available...
-
- Description:
- logo.scn - logo of my institute, INESC
- h2so4.scn - molecule H2SO4
- vitam_a1.scn - vitamin A1
- header.scn - include for previous 2
- balls.scn - balls
