glGetClipPlane(3G)


NAME

  glGetClipPlane - return the coefficients of the specified clipping plane


SYNOPSIS

  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 coefficients 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 equation.


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().
