Just a quick post to celebrate that I’ve updated ooc_svo_builder, the Sparse Voxel Octree builder I’ve written for my paper in Computer Graphics Forum. The updated version has some bugfixes, and profits from some performance improvements in morton code encoding/decoding from the libmorton project. Also nice to see how at High …
For future research and publication, I’ve been updating my Out-Of-Core Sparse Voxel Octree Builder (or ooc_svo_builder, if you’re in a hurry) based on our HPG paper. It’s faster, cleaner and more fun! Source, Win64/Linux64 binaries and manual can be found in the github repository. It also builds on OSX. New …
UPDATE 2016: I’ve bundled and improved a lot of these methods in a library called libmorton. Read about it here. The code used in this post is outdated and might have bugs. Keeping this post online for reference, but I highly suggest using libmorton for actual implementations. In my research …
Since the source code of our Out Of Core SVO Builder pipeline was posted on Github last month, a lot of people have reported bugs and suggested fixes. It’s being actively integrated and used in several interesting projects, of which I hope to write more later. Thanks to all of you, …
I promised to get my source code for our HPG 2013 paper Out-of-Core Construction of Sparse Voxel Octrees out, so here it is! It’s unimaginatively titled ooc_svo_builder. It’s not always evident and/or easy to release code made in an academic context, but since the paper is pretty clear on algorithm details, we thought …
After giving my talk Out-of-Core Construction of Sparse Voxel Octrees at the High Performance Graphics conference in the Hilton, Anaheim, I’ve placed the slides (PDF) on the project page. I’m working to package some source code and cooking up some usable binaries for other people experimenting with out-of-core SVO construction. Since I’m …
So I guess it’s official now! Our paper on out-of-core construction of SVO’s was accepted for the High Performance Graphics 2013 conference. I’ll be presenting the paper in Anaheim, California, 19-21st of july. Here’s a link to the project page, which contains a pre-print and some additional material (more to be …
Hi there, time for some updates on my voxel rendering pipeline! Lot of work behind the scenes last month, and now taking some time to pause and reflect on where the interesting research opportunities are. The lowdown for people just joining in: I’m building a Sparse Voxel Octree raycaster, so …
A short video I made demonstrating the improvements in my voxelizer, a higher grid resolution (1024x1024x1024) and multiple light sources.
Just a quick piccie: thanks to optimizations in my out-of-core octree building algorithm, I can now render even bigger voxel fields (1024^3), which is about 107 million voxels. Reading in the data is the slowest part, the actual building of the octree is blazingly fast (< 500 ms), since the …
