基于浮雕纹理贴图的复杂模型快速显示

A Relief-Texture-Mapping Based Fast Display Method of Complex Models

提出了一种采用浮雕纹理贴图技术对复杂网格模型进行快速显示的方法,采用虚拟拍照方法生成原始模型相应的浮雕纹理,将原始模型简化成六幅浮雕纹理和一个长方体。该方法与传统的计算三角片面的投影方法相比在速度上有很大提高,且显示速度与生成的浮雕纹理的分辨率有关,而与原始模型的复杂程度无关。

This paper presents a fast rendering method of complex models based on relief texture mapping technology. The method of virtual photograph is used to generate relief textures corresponding to the origin model that is simplified to six relief textures and a cuboid later. This method is much faster than conventional method of computing the projection of every triangle, and the speed is only related to the resolution of the relief texture generated but not to the complexity of the origin model.
