[Creating Procedural Textures] 由程序主生贴图,然后设置给Material.首先定义需要的数据: 在Start方法中完成初始化,注意设置的是_MainTex. 实现GenerateParabola方法,算的是到中点的距离除以半径的百分比: [How it works] 下图也是上述Shader产生出的图像,中心点高亮,向边框逐渐变暗. [其它生成算法] 1.使用sin函数的环生成算法. 生成结果如下:…

BACKGROUND The evolution of graphics rendering technology has led to the development of procedural techniques for describing various steps in the rendering process. Procedural geometry is useful as a mechanism for producing arbitrarily complex geomet…

原文地址:https://github.com/AnalyticalGraphicsInc/cesium/wiki/Fabric 介绍 Fabric 是Cesium中基于JSON格式来描述materials的机制.材质描述多边形.折线.椭球等对象的外观特征. 材质可以简单的是覆盖一张图片,或者是条纹或者棋盘图案.使用Fabric 和GLSL,可以从零开始写脚本新建材质,也可以从现有的材质中派生.比如潮湿碎裂的砖块可以使用程序生成的纹理.凹凸贴图和反射贴图来组合. 对象通过material 属性来…

前言:感慨于居然不用tesselation也可以产生这么复杂的地形,当然致命的那个关于不能有洞的缺陷还是没有办法,但是这个赶脚生成的已经足够好了,再加上其它模型估 计效果还是比较震撼的.总之好文共分享吧.Ryan GeissNVIDIA Corporation 1.1 Introduction Procedural terrains have traditionally been limited to height fields that are generated by the CPU and…
