Node Element

Specification Version: 1.4

Category: Joints (See list of specification categories)

Introduction

Add Support for Bone Tail and Bone Roll

Concepts

Collada provides Joint nodes with a joint transform matrix. In Blender we have Bone Head (equal to the Collada Joint location) and Bone Tail (no corresponding element in Collada). The distance vector from Bone tail to Bone head defines the bone orientation (rotation). We want to add the Bone tail for having full information about the Skeleton (Rig).
