   Texture rotation on a point sprite
  Hi all,does anyone know how to rotate a texture on a point sprite. Is there a way or so you can get the texture coordinates and adjust them or something like that??Grtz Frank   
  I was wondering the exact same thing some time ago. I tried using the texture transform matrices on the device, but I couln't get those working at all with point sprites. You might be able to write a pixel shader that rotates the UV coordinates around 0.5;0.5 to solve the problem, but I don't know how point sprites are handled in shaders so it's just a guess.I ended up using billboards when I needed rotating textures, so I can't verify if the shader idea actually works. Anyway, the billboard approach is quite easy to set up and it gives you a bit more freedom, like no restriction on the size, so it might be worth considering too.Hope this helps... a bit :)
