FreeSG is a portable, high-level 3D engine with an emphasis on generality. It is designed as a component to be integrated, as opposed to an application framework. Its goal is to support applications ranging from small 3D games running on portable consoles to large simulations that must be rendered photorealistically using fourth-generation graphics hardware.
bwfirt is a framework for benchmarking ray tracing kernels in the context of a realistic light simulation application. The most important capabilities tested here are: fast ray shooting and visibility functions for incoherent mono-rays (no bundles), numerical robustness, and small memory footprint. The framework implements a simple pathtracer to generate rays with a real-life distribution. Developers can easily plug in their cores to the framework, which then compiles the output images, running times, and memory utilizations of the different kernels into a PDF, providing a clear comparison.
Fountain 3D is a little J2ME toy and a technology demo for a custom-made 3D wireframe engine with some benchmarking abilities thrown in. The camera is fully controllable by the user together with the simple particle simulation. The software doesn't require hardware acceleration; all J2ME compliant mobiles are supported.
QuartzCrystal is an application for rendering Quartz compositions to QuickTime movies and image sequences. It supports third party plugins (using both the official and unofficial API), as well as unsafe patches. It also supports spatial supersampling (antialiasing) and temporal supersampling (motion blur).
