Out of Core SVO Builder: 1.2 release

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 …

Out Of Core SVO Builder: 1.1 release

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, …

Out-Of-Core SVO Builder: Source and binaries available

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 …

HPG 2013: Out-Of-Core Construction of SVO’s: Slides available

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 …

Sparse Voxel Octree Raycasting: January Progress Report

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 …

Rendering bigger voxel sets

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 …

An accurate method for Voxelizing Polygon Meshes

Transforming a polygon mesh into a 3D grid / voxel data set is still the quickest way to play with some interesting data in any voxel-based application. You can do this interactively on the GPU, using Eisemann/Décoret’s method, described in Single-pass GPU solid voxelization for real-time applications (2008). When it comes to …
