Gl.GetClipPlane (gb.opengl)
Static Function GetClipPlane ( Plane As Integer ) As Float[]
Return the coefficients of the specified clipping plane.
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_PLANE
where i ranges from 0 to the value of Gl.MAX_CLIP_PLANES - 1.
- 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).
Description
Gl.GetClipPlane returns in
equation the four coefficients of the plane equation
for
plane.
Notes
It is always the case that Gl.CLIP_PLANE
=
Gl.CLIP_PLANE0 +
.
If an error is generated,
no change is made to the contents of
equation.
Errors
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.
