glGetClipPlane(3) glGetClipPlane(3)
NAME
glGetClipPlane - return the coefficients of the specified clipping
plane
C SPECIFICATION
void glGetClipPlane( GLenum plane,
GLdouble *equation )
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 <= i <
GL_MAX_CLIP_PLANES.
equation Returns four double-precision values that are the coeffi-
cients of the plane equation of plane in eye coordinates.
The initial value is (0, 0, 0, 0).
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 equa-
tion.
ERRORS
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.
