atmossphere volume in arnold

rendered with Arnold in Houdini. I’ve tried the atmosphere volumes the first time. easy to setup. The render time was quite slow on the volumes, typically for volumes, but much faster then render the screen envr with VDB cloud. I’ve used a mesh light for inner character illumination.  it’s a shame I could not useContinue reading “atmossphere volume in arnold”

light simulation

I’ve made a simple scene to test the physics of light. for proper light calculation, I used spectral render Indigo and Octane. Indigo has multiple Engines, standard Spectral Path tracer on CPU or GPU and Bidirectional path tracing with MTL sampling (metropolis Light Transport). Octane has only default Spectral Path tracer on GPU but includesContinue reading “light simulation”

NNody simulation with openCL

an N-Body simulation which calculates a gravity field and corresponding velocity and acceleration contributions accumulated by each body in the system from every other body. Shows how to mitigate computation between all available devices including CPU and GPU devices, as well as a hybrid combination of both, using separate threads for each simulator. the setupContinue reading “NNody simulation with openCL”
