Summary
This scene shows shadows from three different lights(pure white, redish, blueish).
Rendering uses BVH acceleration and adaptive supersampling with two levels of subdivision.
Scene Setup
The camera for the scene is setup at (0,0,4) for the eye point, with a view direction of (0,0,-1) and a view up direction of (0, 1,0 ). The view plane distance is 6, and the horizontal camera angle is PI / 6.
The scene has three point light sources:
- a white light at (0, 15, 5)
- a redish light color=(0.5, 0.1, 0.2) at ( 5, 15, 5)
- a blueish light color=(0.2, 0.1, 0.5) at ( -5, 15, 5)
The scene has a floor (made from a scaled cube) underneath to provide a surface for shadows. The other objects are four spheres, a cube, a mesh cylinder, a bunny, and a teddy bear.
