Is there an effect that can simulate stretching a sprite or atlassprite along one of its dimensions? Something like a isometric "pinch" or taper along one axis to make a sprite appear to stretch into 3d?

Just thinking out loud...

I once played with a sprite's camera, and it game me the effect you describe in this post... I don't really know how I achieved it, but I was playing with the camera and the sprite looked like it had volume, like depth or something...

I may be wrong, maybe there's a better way to do this...

its a taper I want to do, like a real-time distortion grid applied to sprites. Camera tricks sound interesting though. Is there any documentation on the camera class yet?

Its a hack, but if you subclass Sprite you could do something like:
```
- (void) draw
{
  glPushMatrix();
  //rotate 30 degrees along y axis
  glRotatef( 30.0, 0.0f, 1.0f, 0.0f );
  [super draw];
  glPopMatrix();
}
```
Obviously wouldnt work with an Atlas Sprite.

You could also play with Director's -set3Dprojection and change the fov to make it more/less dramatic
