Bumpmapping figured out

quarn has been doing a bit of research on how bumpmapping works on the DC, and he has posted his finding over at boob! [br][br]I decided that it was time to figure out how the bumpmapping works on the dreamcast. Remembering that there was a maple bus patent available, I could quickly search and find another patent describing how the bumpmapping used by the pvr2dc is used. For your convenience I have compiled a pdf, created a tool for creating bumpmaps, and also made an example showing how to use bumpmapping with kos.[br][br]Enjoy! =)

sorry posted in the wrong forum :-[

Great news! I can't wait to see this being used :)

Can this boost DC's homebrew graphics?

Hi.

josemci no, Bumpmapping is just a Texture effect that DC does by HW.

Look here to see what Bumpmapping is:

Could this be implemented in Quake, to give a teneabrae like effect on the DC version of quake?

Hi.

Here is the bumpmapping example compiled:

(the *.bin inside that Zip file is unscrambled)

all thanks go to quarn

But indirectly it will boost the gfx, right? If people learn to use it there is a new possibility to make game better-looking...
