Summary
| Description |
English: A surface and its apparent contour. Given a surface, a light source and screen, the apparent contour is found by first finding points on the surface where a ray from the light source is tangent, to the surface, and then projecting that onto the screen. In the simple case, here, the apparent contour is simply the boundary of the Silhouette. In other case it can contain points in the interiour. |
