OOC SVO CGF article

Out-Of-Core SVO article in CGF

Just a quick update: an updated version of our Out-of-Core SVO construction paper can be found in Computer Graphics Forum. Lots of improvements were made, performance is better and we show an example on how to sample other vertex attributes (like color). For more information, have a look at the project …

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 …

Sparse Voxel Octree Ray Casting: Texture update

After working on the Out Of Core SVO Builder for the last few months (Paper, Github), I did some hacking on my Voxel Raycaster and voxel pipeline so it now supports sampling voxel colors from textures, which allows for some nice rendering. The details: Simple C++ CPU implementation of Voxel Raycasting. …

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 …

Real-time Suggestive Contour Rendering

Realized I hadn’t posted this video yet: a couple of months ago, I took a break from the voxels and octrees to redo my Suggestive Contours GPU implementation. My shader-based approach combines the advantages of an object-space method in an image-based approach: It works for high-polycount models Real-time control over …

Out-Of-Core Sparse Voxel Octree Building: Skipping empty space

I’m currently rewriting my Sparse Voxel Octree builder (and the preceding voxelization pipeline) for a paper I’m writing and hoping to submit to the HPG (High Performance Graphics) conference. The goal is to have a total out-of-core pipeline to go from polygon mesh to an annotated SVO. Annotated, as in: …
