cuda2GLCore: CUDA to OpenGL textures

I made a new implementation of the Cuda2GL sample provided in the CUDA Samples by Nvidia. The sample shows how to generate a texture in CUDA and use it in an OpenGL context without copying it to main memory. The original implementation uses Glut and OpenGL immediate mode (Compatibility profile) to draw the resulting texture. The sample …

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 …

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 …

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 …

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: …
