pixel shader displacement mapping (sortof)

I thought I''d share something, The other day I saw an article on opengl.org about per-pixel displacement mapping (here), which looked mighty impressive and I wanted to try it out. It''s just that it a), it didn''t run, and b), needed absolutly massive ''4d'' textures.. So I decided to try and write my own. (Using just the height stored in the alpha of the normal map). Although I bumped into the limits of my radeon (and therefor couldn''t get things as accurate as I want) this is the result (two triangles). I''m quite happy. it doesn''t slow things down too much either (about 15% slower over normal PPL lighting). If enough people want a description of how I did it I suppose I can write something up. Anyway. Just thought I''d share some fun I had. :D | - Project-X - On hold (kindof ).. - | - adDeath - | - email me - |
