Detailed Description

+This class is a vertex program. +

+D3D / OPENGL compatibility notes: --------------------------------- +

+To make your program compatible with D3D and OPENGL nel drivers, please follow thoses directives to write your vertex programs +

+

    +
  • Use only v[0], v[1] etc.. syntax for input registers. Don't use v0, v1 or v[OPOS] etc..
  • Use only c[0], c[1] etc.. syntax for constant registers. Don't use c0, c1 etc..
  • Use only o[HPOS], o[COL0] etc.. syntax for output registers. Don't use oPos, oD0 etc..
  • Use only uppercase for registers R1, R2 etc.. Don't use lowercase r1, r2 etc..
  • Use a semicolon to delineate instructions.
  • Use ARL instruction to load the adress register and not MOV.
  • Don't use the NOP instruction.
  • Don't use macros.
+-> Thoses programs work without any change under OpenGL. -> Direct3D driver implementation will have to modify the syntax on the fly before the setup like this:
    +
  • "v[0]" must be changed in "v0" etc..
  • "o[HPOS]" must be changed in oPos etc..
  • Semicolon must be changed in line return character.
  • ARL instruction must be changed in MOV.
+Behaviour of LOG may change depending on implementation: You can only expect to have dest.z = log2(abs(src.w)). LIT may or may not clamp the specular exponent to [-128, 128] (not done when EXT_vertex_shader is used for example ..) +

+Depending on the implementation, some optimizations can be achieved by masking the unused output values of instructions as LIT, EXPP .. +
