Source Image:
- uses signed distance functions to model a mug, a pair of scissors, and the ground plane
- SDFs are combined using smooth blending and smooth subtraction operations
- features several different colors of materials
- Lambertian shading is applied to all materials
- soft shadows are cast by SDF primitives
- Scissors and objects are animated by moving their local origins according to time modified by Bias and Gain functions, for smoother, non-linear motion.
- Features three different lights: one to cast shadows, one to provide ambient light, and one to serve as a fill light
- Rendering optimized to allow for smoother animation by limiting how long rays can extend during ray-marching and only checking for scene geometry (during ray-marching and shadow-marching) within a bounding box
