Beispiel

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

Häufige Annahme

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

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• 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.
