In this example, from the programming guide[1], the indexes 2 and 3 don't seem to be doing anything useful. I can remove them and the output doesn't change, or change them to 5 and 6 with no effect. It seems like the writer got slightly confused and was trying to index the coordinates rather than the vertices? I believe the 2 and 3 are out-of-bounds indexes, and gl is igoring them rather than throwing an error, which surprises me, but I'm not at all experienced.
Please correct me if I'm wrong. Vertices can also be drawn out of order and more than once by using the > pyglet.graphics.draw_indexed<http://www.pyglet.org/doc/api/pyglet.graphics-module.html#draw_indexed> > function. > This requires a list of integers giving the indices into the vertex data. > The following example draws the same two points as above, but indexes the > vertices (sequentially): > pyglet.graphics.draw_indexed(2, pyglet.gl.GL_POINTS, > [0, 1, 2, 3], > ('v2i', (10, 15, 30, 35)) > ) [1] http://www.pyglet.org/doc/programming_guide/drawing_primitives.html -- You received this message because you are subscribed to the Google Groups "pyglet-users" group.
