Polygonal Techniques
Tomas Akenine-Möller, Eric Haines, Naty Hoffman · 2019
Up to this point, we have assumed that the model we rendered is available in exactly the format we need, and with just the right amount of detail. In reality, we are rarely so lucky. Modelers and data capture devices have their own particular quirks and limitations, giving rise to ambiguities and errors within the data set, and so within renderings. This chapter discusses a variety of problems that are encountered within polygonal data sets, along with some of the fixes and workarounds for these problems. In addition, techniques to efficiently render polygonal models are presented.
