3D Implementation of SVG

摘要: 针对SVG在3D图形的描述与绘制上存在局限性的问题，提出了一种SVG的3D实现方法；详细介绍了SVG的2D坐标系到3D坐标系的转换原理，给出了转换到3D坐标系后的SVG-3D图形的绘制与操控流程，并以在3D场景中绘制一个正立方体和圆球体为例，介绍了在HTML页面中采用JavaScript创建3D场景和绘制与操控这2个图形的实现。

Abstract: In view of problem of limitation on description and drawing of 3D graph by SVG, the paper proposed a 3D implementing method of SVG. It introduced conversion principle of 2D coordinate to 3D coordinate of SVG in details, gave processes of drawing and operation control of SVG-3D graph on 3D coordinate. Taking drawing a cube and a spherosome in 3D scene as example, it expounded implementation of creation of 3D scene and drawing and operation control of the two graphs in HTML page by use of JavaScript.
