OpenGL extension NV.transform_feedback
 
This module customises the behaviour of the 
OpenGL.raw.GL.NV.transform_feedback to provide a more 
Python-friendly API
 
Overview (from the spec)
        
        This extension provides a new mode to the GL, called transform feedback,
        which records vertex attributes of the primitives processed by the GL.
        The selected attributes are written into buffer objects, and can be
        written with each attribute in a separate buffer object or with all
        attributes interleaved into a single buffer object.  If a geometry program
        or shader is active, the primitives recorded are those emitted by the
        geometry program.  Otherwise, transform feedback captures primitives whose
        vertex are transformed by a vertex program or shader, or by fixed-function
        vertex processing.  In either case, the primitives captured are those
        generated prior to clipping.  Transform feedback mode is capable of
        capturing transformed vertex data generated by fixed-function vertex
        processing, outputs from assembly vertex or geometry programs, or varying
        variables emitted from GLSL vertex or geometry shaders.
        
        The vertex data recorded in transform feedback mode is stored into buffer
        objects as an array of vertex attributes.  The regular representation and
        the use of buffer objects allows the recorded data to be processed
        directly by the GL without requiring CPU intervention to copy data.  In
        particular, transform feedback data can be used for vertex arrays (via
        vertex buffer objects), as the source for pixel data (via pixel buffer
        objects), as program constant data (via the NV_parameter_buffer_object or
        EXT_bindable_uniform extension), or via any other extension that makes use
        of buffer objects.
        
        This extension introduces new query object support to allow transform
        feedback mode to operate asynchronously.  Query objects allow applications
        to determine when transform feedback results are complete, as well as the
        number of primitives processed and written back to buffer objects while in
        transform feedback mode.  This extension also provides a new rasterizer
        discard enable, which allows applications to use transform feedback to
        capture vertex attributes without rendering anything.
