+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><li>Use only c[0], c[1] etc.. syntax for constant registers. Don't use c0, c1 etc..</li><li>Use only o[HPOS], o[COL0] etc.. syntax for output registers. Don't use oPos, oD0 etc..</li><li>Use only uppercase for registers R1, R2 etc.. Don't use lowercase r1, r2 etc..</li><li>Use a semicolon to delineate instructions.</li><li>Use ARL instruction to load the adress register and not MOV.</li><li>Don't use the NOP instruction.</li><li>Don't use macros.</li></ul>
+<p>
+-&gt; Thoses programs work without any change under OpenGL. -&gt; 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><li>"o[HPOS]" must be changed in oPos etc..</li><li>Semicolon must be changed in line return character.</li><li>ARL instruction must be changed in MOV.</li></ul>
+<p>
+Behaviour of LOG may change depending on implementation: You can only expect to have <a class="el" href="a04223.html#a574">dest.z</a> = log2(abs(<a class="el" href="a04223.html#a575">src.w</a>)). 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 ..<p>
