Hi there !!
First, hello to all the OpenGL-Coders !
Next, my problem: I wrote a small particle animation using 2D Textures. So, when I set my Viewpoint in front of the particles, I see them clearly. As I set the Viewpoint on Top, I can't see anything becouse these particles are only 2-dimensional. Has anybody an idea for rotating each particle to the coordinates of my eye-point like doing a coordinate transformation ? Please help me!!!
