NAME

       glPauseTransformFeedback - pause transform feedback operations

C SPECIFICATION

       void glPauseTransformFeedback(void);

DESCRIPTION

       glPauseTransformFeedback pauses transform feedback operations on the currently active transform feedback object. When transform feedback
       operations are paused, transform feedback is still considered active and changing most transform feedback state related to the object
       results in an error. However, a new transform feedback object may be bound while transform feedback is paused.

ERRORS

       GL_INVALID_OPERATION is generated if the currently bound transform feedback object is not active or is paused.

NAME

       glDrawTransformFeedback - render primitives using a count derived from a transform feedback object

C SPECIFICATION

       void glDrawTransformFeedback(GLenum mode, GLuint id);

PARAMETERS

       mode
	   Specifies what kind of primitives to render. Symbolic constants GL_POINTS, GL_LINE_STRIP, GL_LINE_LOOP, GL_LINES,
	   GL_LINE_STRIP_ADJACENCY, GL_LINES_ADJACENCY, GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, GL_TRIANGLES, GL_TRIANGLE_STRIP_ADJACENCY,
	   GL_TRIANGLES_ADJACENCY, and GL_PATCHES are accepted.

       id
	   Specifies the name of a transform feedback object from which to retrieve a primitive count.

DESCRIPTION

       glDrawTransformFeedback draws primitives of a type specified by mode using a count retrieved from the transform feedback specified by id.
       Calling glDrawTransformFeedback is equivalent to calling glDrawArrays() with mode as specified, first set to zero, and count set to the
       number of vertices captured on vertex stream zero the last time transform feedback was active on the transform feedback object named by id.

ERRORS

       GL_INVALID_ENUM is generated if mode is not an accepted value.

       GL_INVALID_VALUE is generated if id is not the name of a transform feedback object.

       GL_INVALID_OPERATION is generated if a non-zero buffer object name is bound to an enabled array and the buffer object's data store is
       currently mapped.

       GL_INVALID_OPERATION is generated if a geometry shader is active and mode is incompatible with the input primitive type of the geometry
       shader in the currently installed program object.

       GL_INVALID_OPERATION is generated if mode is GL_PATCHES and no tessellation control shader is active.

       GL_INVALID_OPERATION is generated if glEndTransformFeedback() has never been called while the transform feedback object named by id was
       bound.
