TriMesh2 Fork – A library for 3D mesh editing and I/O

During my first years in graphics development, I relied heavily on Szymon Rusinkiewicz’s C++ TriMesh2 library. It’s a nice set of tools for 3D mesh input/output, basic visualization and processing. I’ve come to use it in most of my projects. It imports .obj, .3ds and .ply files (amongst others), and puts …

CUDA Voxelizer v0.1

Time to release something that’s been gathering dust on my hard drive for a bit too long: I wrote a CUDA-accelerated voxelizer. It converts polygon meshes into annotated voxel grids. You can download source code and executables on Github. Written in C++ / CUDA Outputs data to .binvox file format …

Libmorton: A library for Morton order encoding / decoding

For my graphics research, I ended up having to encode/decode 3D coordinates into Morton order / Z-order a lot.  For a detailed explanation on how I use them and what they are, check this blog post, which sparked an interesting discussion on the implementation details, and turned out to be a popular …

Out-Of-Core SVO Builder v1.3

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 …

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 …
