Here you can find tutorials and simple solutions for some common graphics programming problems and using some of the code releases.
Poisson disk sample sets provide improved sampling quality to most problems. This solution explains how to use the source code for weighted sample elimination for generating poisson disk sample sets in any sampling domain.
I use the BCC file format for yarn-level cloth models. You can find the detailed description of the BCC file format on the Yarn-level Cloth Models page on my website. This solution presents a way of easily loading these files.
Detecting OpenGL errors has been a common problem. Old OpenGL versions do not give you error messages unless you ask for them. The new versions allow you to create a debug callback. This solution provides simple ways for retrieving OpenGL errors that help you locate the problems in your code.
This solution presents a way of using cyTimer code release to easily analyze the performance of your code (Note that cyTimer requires Windows operating system). Using the code provided in this solution it very simple to use many timers and measure the performance of each part of your code and find the bottleneck.
