PBR真实环境贴图渲染教程(英文PDF) Gumroad – Guide for Environment PBR Texture Creation using Photogrammetry

英文PDF文档，介绍利用实拍扫描照片来制作PBR贴图材质。

PBR全称(Physicallly-Based Rendering)。笼统的说，就字面含义可以看出，这是一种基于物理规律模拟的一种渲染技术。最早用于电影的照片级真实的渲染。近几年由于硬件性能的不断提高，已经大量运用于PC游戏与主机游戏的实时渲染。几款著名的3D引擎均有了各自的实现(UnrealEngine 4, CryEngine 3, Unity 3D 5)

This document is a result of over two years of my photogrammetry research. Has 193 pages and is stored in PDF format.Covers all key information I thought might be useful when building photogrammetry based PBR textures.It wasn’t my intention to create a simple step by step tutorial but a useful guide into surface scanning.I wanted to scratch my photogrammetry experience together and create something, that would help to save somebody’s time, learn on mistakes I made and best practices I found.
