Start with one material

Describe a Dolphin surface as a small Yeho function.

A surface function answers: what material should be here? It receives a position and returns color, roughness, metallic response, and emission. We can begin with the same answer everywhere. This example uses the Dolphin materials, math, and spatial3d packages. It prints a sampled material value in the console. To see the material on a sphere, use the Atlas surface workshop and its compiled CPU reference preview.
