Three particles works as billboards always facing the screen. Since I'm using an animated texture on a plane mesh, I'd like to simulate that effect without using particles. I tried to do:
obj.lookAt(camera.position);
obj.up = camera.up;
But, that doesn't really do what I was trying to achieve. Since that way obj is not parallel to the screen. I guess I have to project/unproject coordinates but didn't really get how to do that.
What's the best way to achieve it?
