Rotate quads: vertex or texcoord?

March 5, 2009 | 11:15 am


I have a scene full of quads which have the same texcoord (exactly the same image and aspect) with blend enabled.

I would like these quads to be oriented in different direction.

Should I do this by rotating the quads themselves or their own individual texture coordinates,
and how can I do that?

Thank you.

rotate the quads, definitely.
andrew b. posted the formula ages ago, i used it on several of my pojects. its a little low level then simple rotatexyz, but using matrix>>jit.op> is most efficient and when you get comfortable with it. most powerful.

I’ve done a jit.gen porting, maybe it could be improved…
