[Up] C Specification

void glGetClipPlane(
    GLenum	 plane,
    GLdouble	 *equation)

[Up] Parameters

plane
Specifies a clipping plane. The number of clipping planes depends on the implementation, but at least six clipping planes are supported. They are identified by symbolic names of the form GL_CLIP_PLANEi where 0 .le. i < GL_MAX_CLIP_PLANES.
equation
Returns four double-precision values that are the coefficients of the plane equation of plane in eye coordinates. The initial value is (0, 0, 0, 0).

[Up] Description

glGetClipPlane returns in equation the four coefficients of the plane equation for plane.

[Up] Notes

It is always the case that GL_CLIP_PLANEi = GL_CLIP_PLANE0 + i.

If an error is generated, no change is made to the contents of equation.
