Mesh.bounds

説明

The bounding volume of the Mesh.

This is the axis-aligned bounding box of the mesh in its own space, so the bounds don't change if you change the Transform position, rotation or scale. The Renderer.bounds property is similar but returns the bounds in world space.

// Generates planar UV coordinates independent of mesh size
// by scaling vertices by the bounding box size
