Arnold toon shader test

I am starting to test Arnold Renderer in Houdini Solaris. it took me a while to figure how to makes it work in Solaris context. I’ve need to create beauty render pass and render product with contour sampling. its work pretty good, there some crashes from Solaria. the live render navigation is difficult to navigate,Continue reading “Arnold toon shader test”

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”

Renderman Spline rendering

I’ve tested RenderMan with spline rendering. it’s much faster compared with baked Geometry. the spline primitives are very good in Renderman. I’ve stopped the test with mantra after 10 minutes, it is super slow even with optimized render settings. the Renderman images rendered for 3:20 on a 6 core Xeon 2.7ghz with pxr pathtracer. 4kContinue reading “Renderman Spline rendering”

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”
