Texture tiling and swizzling 原帖地址:http://fgiesen.wordpress.com If you’re working with images in your program, you’re most likely using a regular 2D array layout to store image data. Which is to say, it’s basically a 1D array of width * height pixels,…

图文详解Unity3D中Material的Tiling和Offset是怎么回事 Tiling和Offset概述 Tiling表示UV坐标的缩放倍数,Offset表示UV坐标的起始位置. 这样说当然是隔靴搔痒. 下面用*.3ds文件作为模型,介绍Tiling和Offset到底是怎么回事. 3DS格式解析 比如我有这样一个tank_player.3ds模型.右侧的'select'处的图片就是贴图. *.3ds文件最基本的内容包括顶点列表Vertices.贴图坐标列表UVs.面列表Faces.其中Ve…
