Exemplo

MeshSurfaceSampler.sample populates target position, normal, color, and UV vectors in place and returns the sampler instance itself rather than a new point object.

MeshSurfaceSampler.sample returns a new sampled point object or Vector3 instance.

O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.

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