这份文件描述了COLLADA？模式。COLLADA是一项协作设计活动，它定义了一个基于XML的模式，使3D创作应用程序能够在不丢失信息的情况下自由交换数字资产，使多个软件包能够组合成极其强大的工具链。 本文档的目的是提供足够详细的COLLADA模式规范，使软件开发人员能够创建工具来处理COLLADA资源。特别是，它与那些从数字内容创建（DCC）应用程序、3D交互式应用程序和工具链、原型工具、实时可视化应用程序（例如视频游戏和电影行业中使用的应用程序）以及CAD工具导入或导出的应用程序相关。 本文档涵盖了COLLADA模式的初始设计和规范，以及对COLLADA出口商的一组最低要求。本文件涵盖以下信息: COLLADA模式的初始设计和规范； COLLADA工具的要求和对COLLADA出口商的一套最低要求； COLLADA编程的详细解释； 描述几何图形、动画、蒙皮、资产和场景的核心元素； 物理模型，视觉效果（FX），动画的边界表示（B-rep），运动学。 该文档没有指定用于查看或处理COLLADA数据的运行时架构的实现或定义。

This document describes the COLLADA？ schema. COLLADA is a Collaborative Design Activity that defines an XML-based schema to enable 3D authoring applications to freely exchange digital assets without loss of information, enabling multiple software packages to be combined into extremely powerful tool chains. The purpose of this document is to provide a specification for the COLLADA schema in sufficient detail to enable software developers to create tools to process COLLADA resources. In particular, it is relevant to those who import to or export from digital content creation (DCC) applications, 3D interactive applications and tool chains, prototyping tools, real-time visualization applications such as those used in the video game and movie industries, and CAD tools. This document covers the initial design and specifications of the COLLADA schema, as well as a minimal set of requirements for COLLADA exporters. This document covers the following information:

• initial design and specifications of the COLLADA schema;
• requirements of COLLADA tools and a minimal set of requirements for COLLADA exporters;
• detailed explanations for COLLADA programming;
• core elements that describe geometry, animation, skinning, assets, and scenes;
• physics model, visual effects (FX), boundary representation (B-rep) of animation, kinematics.

The document does not specify the implementation of, or definition of a run-time architecture for viewing or processing of COLLADA data.
