Convex Screen Shots

These pictures were made before mip-mapping, depth attenuation, and surface waves were implemented.

The Pool

The pictures above demonstrate on-the-fly CSG.
Starting with the scene on the left, the cylindrical tunnel was simply rotated to obtain the scene on the right.
Moving a brick column into the water to demonstrate refraction -- from above, the column appears to bend at the water's surface (left).
From below the surface we see both refraction and total internal reflection (right).


This surreal world contains a conical light source, which the user may "carry" like a flashlight.

Hall of Mirrors

This indulgent scene was created to show off what ray-tracers do best!
