Mesh.bindposes 绑定的姿势

var bindposes : Matrix4x4[]

Description描述

The bind poses. The bind pose at each index refers to the bone with the same index.

绑定的姿势。每个索引绑定的姿势使用具有相同索引的骨骼。

The bind pose is the inverse of inverse transformation matrix of the bone, when the bone is in the bind pose.

当骨骼在绑定的姿势时,绑定的姿势是骨骼变换矩阵的倒转。
