Glxgetclipplane - HP b2600 Reference Manual

glXGetClipPlane

glGetClipPlane: return the coefficients of the specified clipping plane.
C Specification
void glGetClipPlane(
Parameters
plane
equation
Description
glGetClipPlane returns in equation the four coefficients of the plane equation for plane.
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.

GLenum plane,
GLdouble *equation)
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
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).
GL_INVALID_ENUM is generated if plane is not an accepted value.
GL_INVALID_OPERATION is generated if glGetClipPlane is executed between the
execution of glBegin and the corresponding execution of glEnd.
i < GL_MAX_CLIP_PLANES.
