This class is a vertex program.
<p>
D3D / OPENGL compatibility notes: ---------------------------------
<p>
To make your program compatible with D3D and OPENGL nel drivers, please follow thoses directives to write your vertex programs
<p>
<ul>
<li>Use only v[0], v[1] etc.. syntax for input registers. Don't use v0, v1 or v[OPOS] etc..<li>Use only c[0], c[1] etc.. syntax for constant registers. Don't use c0, c1 etc..<li>Use only o[HPOS], o[COL0] etc.. syntax for output registers. Don't use oPos, oD0 etc..<li>Use only uppercase for registers R1, R2 etc.. Don't use lowercase r1, r2 etc..<li>Use a semicolon to delineate instructions.<li>Use ARL instruction to load the adress register and not MOV.<li>Don't use the NOP instruction.<li>Don't use macros.</ul>
-> 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:<ul>
<li>"v[0]" must be changed in "v0" etc..<li>"o[HPOS]" must be changed in oPos etc..<li>Semicolon must be changed in line return character.<li>ARL instruction must be changed in MOV.</ul>
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 ..)
<p>
Depending on the implementation, some optimizations can be achieved by masking the unused output values of instructions as LIT, EXPP ..
