Geodesics and caustics on graph
Geodesics and caustics on graph
Office: SciCtr 434

The picture below shows the caustic of the point (0,0) on the surface z=x4 + y4. Unlike in the pictures in this exhibit done at the beginning of the project, the caustic is drawn here nicer and the geodesic flow is controlled to stay on the unit tangent bundle. We also see the actual surface with the caustic. Click on a picture to see a higher quality (megapixel) picture.
