Hi,

Would somebody please let tell me how to draw QUAD_STRIPS with points in the correct order. Mine keep on twisting from the second Quad that I want to join onto the first quad.
I use four points for the 1st quad, then I want to use 2 for the joining quad.

Thanks

GL_QUAD_STRIP
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 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.
