fast bump mapper

[Heaven/TQA]

as promissed here is a fullscreen 50 fps bump mapper done by fox in 98 which i have found on my old laptop lying for years... of course source code included... i am sure that fox does not mind to publish the source as bump mapping is nothing special anymore...

 

ps. go and play "jade empire" which is a wonderful great game...

fast but uses different technique than real lambertian bump mapping. (like e.g. bump at end of numen demo) Anyway, kudos to fox!

i would say that its nearly the same bump mapper except that the texture is another one??? and there is no moving of the background?

I don't think so. Take a look at the light 'bulb' In fox's code you can see it , in eru's - you don't, you just see the bumped surface.

Maybe the mapper code is similar but it's surely not the same IMO.

what about my bumper? is it using "real lambertian"?

well. not really i'd say. But without the source I could not tell.

i use this method.... source code lies somewhere on a atari ST scsi harddisc... (20MB-disc! jesus...) and the ST is down...
