"Ivory Chess Pieces"

Detailed renders of chess pieces from "The Duel", published a few days ago. Designed and rendered in Blender, showing sub-surface scattering of light through thinner areas of the ivory and traces of fingerprints on the surface of the pieces.

3d rendering of a clock with a spiral spring from the scrapyard, which I made in 1989.
Unique, about 30 cm high, black powder-coated.

FWIW Since discovering Christopher Kulla's #Sunflow renderer[1] back in 2005/6, I had several intense phases & projects in which I've been trying to generate and render similarly complex (erm... "organic") structures, mostly generated via simulating and guiding Diffusion-limited aggregation, and not rendered in realtime, later also using #LuxRender & #Houdini. An early highlight: After garnering some interest via flickr, was asked to render a 10 second opening/growth sequence for a TV show on Channel4. On my Dell XPS schlepp-top, this only took almost a week... 😱

[1] Sunflow was the only open source & easily hackable renderer I knew back then (written in Java to boot) which had native support for rendering particle clouds with millions of particles. Christopher working at Epic now, this link still feels somehow relevant to me...

🎨✨ We introduce a novel anisotropic specular image-based lighting method that serves as a drop-in replacement for the standard bent normal technique. This approach renders materials like brushed stainless steel and fur more realistically.

We derive an analytic formula for determining the major axis of the specular microfacet BRDF and place the environment samples along it, similar to anisotropic texture filtering.

mesh_to_sdf 0.4 is out!

Featuring a new acceleration structure (r-tree) for generic sdf generation (3x faster than my bvh extension) and a fully parallelized version of the grid generation (15x faster than the previous version on a high end cpu).

Shout out to rust concurrency and to @superluminal for the amazing profiler.

The example below is a 256x256x256 grid sdf.

Back in the day, I began my career working on open source rendering software even before open source was fully conceived. Now that I'm no longer part of a corporate behemoth and my time is my own, I'm wondering if there is an open source rendering project out there that might benefit from my contributions. Getting back into coding and working with a group, as well as the warm fuzzies of contributing to an open source project sounds enticing. Any recommendations? #rendering #raytracing
