Clip planes for NV15
OpenGL requires 6 clip planes minimum. NV10 hardware seems to have some commands available for 8 clip planes, but only 6 are available. So we don't know if all 8 clip planes are working or not.
FIFO Commands:
0x600 (NV15_CLIP_PLANE0) 0x610 (NV15_CLIP_PLANE1) 0x620 (NV15_CLIP_PLANE2) 0x630 (NV15_CLIP_PLANE3) 0x640 (NV15_CLIP_PLANE4) 0x650 (NV15_CLIP_PLANE5) 0x660 (NV15_CLIP_PLANE6) 0x670 (NV15_CLIP_PLANE7)
Arguments:
Defining a clipping plane requires 4 floating point values. glClipPlane() function requires double (64 bits) parameters, but the hardware only supports float (32 bits) parameters. A plane is defined by the equation: Ax+By+Cz+D=0.
A (float) B (float) C (float) D (float)
