Full spectral rendering using stochastic progressive photon mapping

We have been experimenting with image based lighting and importance sampling of a HDRI maps – as well as unifying our various ray trace related techniques into a single framework (codename: Cyclops). This framework is to be used for some of our future ray trace related projects, e.g. quick rebuild of acceleration structure as well as predictive rendering. … oh, and everything is GPU based – coded from the ground up (Cuda and OpenCL).

Here is a little movie showing real time simulation of non-linear elastic material properties using the Total Lagrangian Explicit Dynamic FEM. Three different sets of material parameters were used. Our implementation is done in CUDA. Thanks to Brian Bunch Christensen and Jens Rimestad for cooperation on the implementation. The source code is under the LGPL licence and can be found here. Please acknowledge if you use it for your research. Thanks to Movania Muhammad Mobeen for tidying up the project so it…

We are  playing around with our CUDA ray tracing software. The design philosophy is to create a real-time ray tracing experience that allows the user to play with the visual parameters and get an instant feedback. This is not something revolutionary but ray tracing is such a flexible rendering technique, so the basic software can be used in a lot areas. In this demo the user can change and update the material properties at runtime. We finally found a decent…
