"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 einer Uhr mit einer Spiralfeder vom Schrottplatz, die ich 1989 gefertigt habe.
Unikat, etwa 30 cm hoch, schwarz pulverlack beschichtet.

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.
#Uhren -> ambosshg.de/index.php?/categor

Auf einem dunklem Holzblock steht eine schwarze Uhr mit weißen Zeigern, um das Zifferblatt ist eine Spiralfeder gebogen und auf einen 180°-Rohrbogen geschweißt. Daneben ist noch ein Kerzenleuchter mit einer weißen Kerze aus verknotetem Kupferrohr und an der Wand dahinter noch ein Teil eines kakejiku (japanisches Rollbild) mit blauweißen Blütenmotiven zu sehen. A black clock with white hands stands on a dark wooden block; a spiral spring is bent around the clock face and welded onto a 180° pipe bend. Next to it is a candlestick with a white candle made of knotted copper tubing and, on the wall behind it, part of a kakejiku (Japanese scroll painting) with blue and white flower motifs.

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...

3D rendered macromolecule structure grown via Diffusion-limited aggregation simulation implemented in Houdini VEX, ~2018
A cropped detail of a larger 3D rendered text consisting of millions of particles forming letter structures reading "designing seeds". Diffusion-limited aggregation simulation, rendered in Sunflow, 2009
Grayscale 3D render (Sunflow) of particles grown along a 3D bezier spline using Diffusion-limited aggregation simulation. The curve direction controls the growth direction, creating a very organic aesthetic.
My first 3D particle cloud render ever (2006), showing 200,000 iterations of a single particle's random walk through space. Rendered in Sunflow.

🎨✨ 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.

The power armor frame from fallout 4, an exoskeleton with lots of holes. The model is visible on the left, a voxelized version in the middle and a raymarch version of the sdf on the right. The raymarch shows some ghosting near the hands and some aliasing at junctions, both overall the quality is pretty good with both visualizations almost indistinguishable at lower resolution.

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
