Q package:OpenGL

Draws a connected group of quadrilaterals. One quadrilateral is defined for each pair of vertices presented after the first pair. Vertices 2n-1, 2n, 2n+2, and 2n+1 define quadrilateral n. N/2-1 quadrilaterals are drawn. Note that the order in which vertices are used to construct a quadrilateral from strip data is different from that used with independent data.

Treats each group of four vertices as an independent quadrilateral. Vertices 4n-3, 4n-2, 4n-1, and 4n define quadrilateral n. N/4 quadrilaterals are drawn.

This module corresponds to section 4.2 (Query Objects and Asynchronous Queries) of the OpenGL 4.4 specs.

This module offers various texture queries.

This module corresponds to chapter 6 (Quadrics) of the GLU specs.
