示例

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

常见的想当然

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

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• 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.
