After a small break its time for a new competition. This time the execise a little more difficult: You have to
write a tiny gouraud - shader. Due to that you have more time than before to finish this task - deadline
is sunday, september 7,1997 at 21.00 CET .
All contribution have to be sent to Azure again.
Fetch your personal competition package (also including the rules as textfile)
Many thanks to Flynn for preparing the great init-source and screenhandler.
Well - please download the competition package for more detailed rules.
- The aim is to write a routine rendering a gouraud-shaded vector-object to a chunky buffer.
- You are given a full init-routine with chunky screenhandler and two objects. Remember, that your routine must
be able to display both objects (well - two tori :) )
- A sinetable with 1024+256 word-entries and an amplitude of +-32760 is also given.
- The screen you have to render to has a width of 256 and also a height of 256.
- "gouraud.s" is the only file you may change.
- Your routine must utilize both palette ranges. (2x128 colors) A colorflag is provided
for each triangle in the object-file.
- All brightness-calculations have at least 8.8 accuracy. (No ugly shading-bugs)
- The triangle-drawer has to be accurate. No gaps between the polys! (black dots etc.. )
- Two rotation angles are given. (You can control them manually by pressing the
right mousebutton while moving mouse)
- The routine must be working on 68020-68060! When you are sick enough to use
selfmodifying code, make sure that it does also work on 060.
