BACKGROUND Today's graphic processing units (GPUs) host all of the computations necessary to generate high-quality graphics on computer screens, leaving a computing device's central processing unit (CPU) available for other tasks. Specifically, GPUs…

A Simple OpenGL Shader Example II eryar@163.com Abstract. The OpenGL Shading Language syntax comes from the C family of programming languages. Tokes, identifiers, semicolons, nesting with curly braces, control-flow, and many key words look like C. GL…

Graphics processing units (GPUs) are specialized hardware units used to render 2-dimensional (2-D) and/or 3-dimensional (3-D) images for various applications such as video games, graphics, computer-aided design (CAD), simulation and visualization too…

BACKGROUND A graphics processing unit (GPU) is a specialized electronic device that is specifically designed to perform operations related to graphics processing. GPUs are often built with a highly parallel structure that provides more efficient proc…

今天工作中需要做一个事情: 在shader内部做一些空间距离上的计算,而且需要对所有的点进行计算,符合条件的显示,不符合条件的点不显示. 思路很简单,在vertex shader内知道顶点坐标,进行计算,算好以后判断是否需要显示,例如设置alpha值,那么再将alpha值传给fragment shader,在里面设置alpha的值就好了. 基本代码如下 // vertex shader #version 300 es in vec4 vPosition; in vec2 vTexCoord; o…

+BIT祝威+悄悄在此留下版了个权的信息说: CSharpGL(14)用geometry shader渲染模型的法线(normal) +BIT祝威+悄悄在此留下版了个权的信息说: 2016-08-13 由于CSharpGL一直在更新,现在这个教程已经不适用最新的代码了.CSharpGL源码中包含10多个独立的Demo,更适合入门参考. 为了尽可能提升渲染效率,CSharpGL是面向Shader的,因此稍有难度. 问题 在处理光照效果等问题时,模型的顶点的法线是必不可少的数据.但是法线并不直接显示…
