摘要： Depth ClampingThat's all well and good, but this:This is never a good thing. Sure, it keeps the hardware from dividing by zero, which I guess is impor... 阅读全文

摘要： Boundaries and ClippingIf you recall back to the Perspective projection tutorial, we choose to use some special hardware in the graphics chip to do th... 阅读全文

摘要： Optimization: Base VertexUsing VAOs can dramatically simplify code. However, VAOs are not always the best case for performance, particularly if you us... 阅读全文

摘要： Overlap and Depth BufferingRegardless of how we render the objects, there is a strange visual problem with what we're rendering:If the smaller object ... 阅读全文

摘要： In this tutorial, we will look at how to deal with rendering multiple objects, as well as what happens when multiple objects overlap.Multiple Objects ... 阅读全文

摘要： Aspect of the WorldIf you run the last program, and resize the window, the viewport resizes with it. Unfortunately, this also means that what was once... 阅读全文

摘要： Perspective ProjectionRecall that our destination image, the screen, is just a two dimensional array of pixels. The 3D rendering pipeline we are using... 阅读全文

摘要： Chapter 4. Objects at RestThus far, we have seen very flat things. Namely, a single triangle. Maybe the triangle moved around or had some colors.This ... 阅读全文

摘要： Multiple ShadersWell, moving the triangle around is nice and all, but it would also be good if we could do something time-based in the fragment shader... 阅读全文
