This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. MeshSurfaceSampler.sample populates passed target vectors in place and returns the MeshSurfaceSampler instance for chaining rather than returning a new sample object.
  2. Calling sample before build throws a TypeError because cumulative distribution weights are uninitialized.
  3. sample interpolates vertex attributes (position, normal, color, uv) across the sampled face using barycentric coordinates.
  4. When geometry lacks a vertex normal attribute, sample computes the geometric face normal and assigns it to targetNormal.
