glGetTexGen

params returns the four plane equation coefficients that specify eye linear-coordinate
generation. Integer values, when requested, are mapped directly from the internal
floating-point representation. The returned values are those maintained in eye
coordinates. They are not equal to the values specified using glTexGen, unless the
modelview matrix was identity when glTexGen was called.
Notes
If an error is generated, no change is made to the contents of params.
Errors
• GL_INVALID_ENUM is generated if coord or pname is not an accepted value.
• GL_INVALID_OPERATION is generated if glGetTexGen is executed between the
execution of glBegin and the corresponding execution of glEnd.
