Ed Angel at the University of New Mexico got me into projecting computer graphics on planetarium-like dome theatres. As a test, I wrote a ray tracer to make an interactive scene consisting of four reflecting spheres, which you can see to the right (try dragging your mouse to see how they inter-reflect). But things get really cool if you place the camera viewpoint right in the center of the four spheres, and then project the result onto a dome. You can see a simulation of that HERE. |
Instructions: Drag the mouse around to change the view. |
