Exemple

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

Ce que l'on suppose souvent

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

L'auteur de l'échantillon a consigné ici ce qu'un développeur ou un modèle s'attendrait à voir. Le contrat ci-dessous est ce qui s'est réellement exécuté.

Contrat

• 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.
