PBR渲染 以金属工作流实现的一套简化的pbs，适合在手机移动平台上运行。 着色器调试： 着色器，查看DebugMode 无完整的输出（高光+漫反射） 漫反射颜色输出 高光颜色计算 正常法线的输出 边缘边缘发光 区别于官方的pbr shader，我们在渲染的时候，可以使用一些自定义的选项。虽然这些效果呈现出来的结果破坏了物理计算出来的结果，但是出于美术或者策划这样或者那样的需求，我们还是这样了。比如说，我们在保证基于物理计算的同时，还加入了边缘发光的效果。类似的我们还可以附加其他效果。当然，我们也有开关来控制这种效果的显示。 我们对PBR使用的公式： 由于移动平台的限制，我们只考虑了主光

投影矩阵的教程 Introduction 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. Projective texture mapping refers both to the way texture coordinates are assigned to vertices, and the way they are computed during rasterization of primitives. We usually think of texture mapping as “the application of a texture image to a primitive,” and while it certainly is that – there is more math going on than most folks think. If you have ever written your own rasterizer with support for mipmap filtered, perspective-correct, projective texture mapping, you no doubt became aware of the many subtle issues involved. We will begin by discussing the way that texture coordinates are computed during rasterization, and then we will discuss methods for assigning the texture coordinates to the vertices. We do not discuss filtering here, but there is a paper on Anisotropic Filtering at the NVIDIA developer web site that provides a good introduction to that topic. Figure 1.

本程序主要演示了利用DirectX可编程流水线技术。代码中运用了HLSL语言去建立效果文件从而实现GPU编程。

本文件介绍了hlsl语法基础 适合搞虚拟现实的初学者 建议入门使用

支持cg hlsl glsl 三种shader language，国内这种资源真的好匮乏呀~~~ 需要visual studio 2008环境。
