marble rendertest

Inspired by great Marble renders and Shader hack by Lee Griggs. I’ve decided to recreate some tricks with different render engines, a little render Comparison. The basic idea, using a glass shader for outter shell and an inner sphere with textured volume to fake depth. this way, you will save a lots of work withContinue reading “marble rendertest”

star simulation with OpenCL

birth of a massive star. for my little #astrophysics exploration, i’ve created a star simulation using openCL in houdini. its based on nbody #physics model, only driven by #gravity. using #nvidia #quadro rtx 5000 #NVIDIAStudio. #arnoldrender the colours are not quite right, I am trying to integrate kelvin colour temperature.  the current colour is basedContinue reading “star simulation with OpenCL”

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”
