问题描述
我正在使用PVR纹理在IOS中使用OpenGL制作3D效果.我不了解.pvr文件.所以请朋友们给我一些有关.pvr文件的想法，以及它在OpenGL中的重要性以及如何实现.我做到了吗?
I am making application with OpenGL in IOS using PVR texture for making 3D effect.I couldn't understand about .pvr files.So please friends would you give idea about .pvr files and what's importance of it in OpenGL and how can i make it?
推荐答案
PVR文件是各种纹理格式(例如PVRTC，RGB565等)的容器.您可以直接使用这些纹理格式.如果使用PNG，则像素可能会预先乘以alpha.
PVR file is a container for various texture format such as PVRTC, RGB565 and so forth. You can use directly these texture formats as is. If you use PNG, pixels might be pre-multiplied alpha.
PVRTC是GPU原生支持的压缩纹理格式(PowerVR MBX或SGX). GPU可以有效地渲染PVRTC.这样会提高帧率.
PVRTC is compressed texture format that is natively supported by GPU (PowerVR MBX or SGX). GPU can render PVRTC effectively. It would increase framerate.
