.NET based OpenGL Hybrid Raytracer
Home / RTG
Powertek - Logo  
RTG is CPU/GPU hybrid raytracer based on the Microsoft .NET Framework. The software taking advantage of current processor and graphics card technology and allows the fast image calculation even in scenes with several 100,000 triangles. The achievable computation times are placed on the level of commercial raytracer, the GPU based raytracer also allows real-time output with up to 50 frames per seconds.
In addition to the integrated raytracers RTG also implements an OpenGL engine, which guaranties a high-quality preview of the scene by using current techniques such as cascaded shadow mapping, shadow volumes and environment mapping.
All used parameters can be changed by the graphical user interface. This include settings for camera, light sources, environment and materials, as well as the settings for the raytracer and the OpenGL engine.
As additional features the generated acceleration structures and the calculated rays can be visualized in the OpenGL engine, and furthermore the shadow data of the engine (depth buffer) and/or the shadow volume data can be dispayed.

The download contains some demo scenes which can be rendered by RTG. The usage of 3rd party models may lead loading or calculation errors since the loaders dont support all tags of all file formats. Therefore the use of ASE, 3ds or ply files are recommended.
Grafics Card - Compatibility
RTG needs at least a NVIDIA GeForce 6 and later. For optimal performance a GeForce 8800GT++ is recommended (tested: GF6800GT, GF7800GS/GT, GF8600GM, GF8800GT, GTX470).
The usage of an GeForce 6 may lead to viewing errors/artefacts.
No guarantie for AMD/ATI graphic cards.
Grafics Card - Drivers
RTG requires an up to date NVIDIA driver (180xx and later).
Versions earlier then 170xx will lead to view/calculation errors.
