BCON24: Create your own Importers and Exporters

Gustaf Waldemarson — Tue, 22 Oct 2024 17:55:24 GMT

It's time for another Blender Conference in Amsterdam! This year, I am holding a talk about how to create custom importer and exporter extensions for Blender. Feel free to tune in after Wednesday the 23rd October at 16:00 on YouTube.

Additionally, you can find the slides, with notes, down below, or on my publications page:

Succinct Opacity Micromaps

Gustaf Waldemarson — Sun, 18 Aug 2024 10:58:18 GMT

Recently, I presented a bit of my work at the High-Performance graphics conference on compressing a relatively new kind of Vulkan® and DirectX® graphics object: the Opacity Micromap. This object is intended to be used as a relatively cheap memory hint to the hardware ray-tracing pipeline to attempt to cut down on the number of times the expensive AnyHit shader has to be called.

It may still be relatively big however; so in this work we introduce a way to interpret the micromap as a tree structure that in turn can be compressed in a very efficient way: Up to 110 times in some actual content.

You can find the presentation, the slides, and the paper itself among my publications.

BCON23: Custom Data in glTF Files

Gustaf Waldemarson — Sat, 20 Jan 2024 14:55:24 GMT

A while back now, I attended the Blender Conference in Amsterdam where I presented a bit of the work I had done related to Blender, glTF and Opacity Micromaps. Despite the 50-min presentation though, I still had a lot of content over that I had to cut out in the interest of time (and presentation coherency). I had hoped to include much of that in this write-up shortly after the conference, but I ended up swamped with work from both Arm and several looming paper deadlines, so I had to postpone it. But here it is now, so better late than never I guess!

Links to the presentation, as well as the slides I used can be found on my publications and presentations page.

Photon Mapping Superluminal Particles

Gustaf Waldemarson — Mon, 08 Jun 2020 09:19:58 GMT

After quite a bit of work, I'm happy to announce my first successfully accepted academic paper: Photon Mapping Superluminal Particles. In this paper we investigated how to render the light generated by particles travelling faster than light relative to the surrounding media, yielding some visually pleasing images.

If you're interested in knowing more, the full paper as well as the presentation at Eurographics 2020 are available via the link above.

This is hopefully the first of several publications to come during my PhD studies, but for now we'll just have to wait and see what the future holds.
