LuxMark v1.0 released: an OpenCL benchmark tool

• Tags: benchmarks OpenCL

LuxMark is a OpenCL benchmark tool. The idea for the program was conceived in 2009 by Jromang. It was intended as a promotional tool for LuxRender. The idea was quite simple, wrap SLG inside an easy to use graphical user interface and use it as a benchmark for OpenCL. After Anandtech adoption of SLG as OpenCL benchmark, the code was finally written and is now available at http://www.luxrender.net/wiki/LuxMark   Read More

PixelLight 0.9.5-R1 released

• Tags: windows framework OpenGL

The new version 0.9.5-R1 of the free open-source, cross-platform 3D application framework PixelLight has been released. OpenGL is used within the main renderer. Beside the usual bugfixing and feature completion, there are several migrations in this release. PixelLight is now using 'nullptr' introduced by C++0x, migrated from C style casts to C++ style casts and under MS Windows, Microsoft Visual Studio 2010 is now used as the main development IDE. There are also new features like the plugin SPARK_PL integrating the free open source particle engine SPARK. The SDK now includes two new demos, one of them shows how picking works.   Read More
