Description

 
glActiveTexture selects which texture unit subsequent texture state calls will affect. The number of texture units an implementation supports is implementation dependent, but must be at least 2.
 
Vertex arrays are client-side GL resources, which are selected by the glClientActiveTexture() routine.

Function zglFogAlphaMode
Specifies the equation to be used to compute the fog alpha color.
Signature
zglFogAlphaMode(intmode)
Arguments
intmode–Three symbolic constants are accepted: GL_REPLACE (OpenGL behaviour, discard fogcolor.alpha, blend to fogcolor RGB and keep primitive alpha), GL_BLEND (full fog color+alpha blending), and GL_MULT (blend to fog alpha multiplied by primitive alpha). The initial fog alpha mode is GL_REPLACE.
Description

This is an extension to the regular OpenGL fog feature which is only available if tkopengl is compiled in emulation mode (DX_EMU_FOG / DX_EMU_FIXFXN).
When drawing transparent objects, GL_BLEND can be used to fade-out primitives (if fog alpha is 0.0) resp. GL_MULT alpha mode can be used to fade to an alpha relative to the primitive alpha (out_alpha = mix(frag_alpha*fog_alpha, frag_alpha, fog_amount)).
