投影纹理映射是Segal [3]描述的一种纹理映射方法，它允许纹理图像像幻灯机一样投影到场景上。图1显示了projspot演示中的一些示例屏幕截图，可在NVIDIA OpenGL SDK中使用。投影纹理映射在各种照明技术中非常有用，包括阴影映射[4]。本文档提供了一些背景知识，并描述了OpenGL中投影纹理映射所涉及的步骤。
Projective texture mapping is a method of texture mapping described by Segal [3] that allows the texture image to be projected onto the scene as if by a slide projector. Figure 1 shows some example screen shots from the projspot demo, available in the NVIDIA OpenGL SDK. Projective texture mapping is useful in a variety of lighting techniques, including shadow mapping [4]. This document provides some background and describes the steps involved in projective texture mapping in OpenGL.
