Static Function GetClipPlane ( Plane As Integer ) As Float
Return the coefficients of the specified clipping 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_PLANE
where i ranges from 0 to the value of Gl.MAX_CLIP_PLANES - 1.
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).
returns in equation
the four coefficients of the plane equation
It is always the case that Gl.CLIP_PLANE
If an error is generated,
no change is made to the contents of equation
Gl.INVALID_ENUM is generated if plane
is not an accepted value.
Gl.INVALID_OPERATION is generated if Gl.GetClipPlane
is executed between the execution of Gl.Begin
and the corresponding execution of Gl.End.
