without precalculated texture angles, i guess that's the fastest way to process it.

Agemixer (09:16:14)
"simple" as that in the end. then it is uust about few lookups for that texture and plot

Agemixer (09:15:11)
light data that reflects on that bump. You only need that 4th table of offswt for lookup, and multiplu that brightness info with the current pixel colour you process

Agemixer (09:13:49)
add sinus multiplier (or sinus lookup table or sth) for that angle, it comes out as X and Y points of offset from that point you going to calculate. So the final 4th texture table defines just offsets where to look at the surrounding texture the light

Agemixer (09:09:45)
So the delta is the difference between heights, you can make a 3rd texture of that height delta info, it defines a reflection angle

Agemixer (09:08:05)
So there is basically that 2D texture and another heights info texture, similiar, kind of.

I figured that outself then it was not the thing anymore, around 2000

Bumpmap has been one of those things I wanted to learn how to make..

d_vibe (09:05:24)
but I refactored it and made it hell lot of faster
