- ; Declare pixel shader version 1.1
- ps.1.1
- ; Define t0 as a standard 3-vector from bumpmap
- tex t0
- ; Perform EMBM to get a local normal bump reflection.
- texbem t1, t0 ; compute new (u,v) values
- #ifndef DO_WATER_ALPHA_TEXTURE
- ; result goes in output color multiplied by diffuse
- mul r0, t1, v0
- #else
- ;alternate version which uses a third texture which provides per-pixel alpha.
- ; result goes in output color multiplied by diffuse
- tex t2 ; get alpha texture
- mul r0.rgb, t1, v0
