Volume Rendering : An Overview
I made a presentation which outlines the different methods for Volume Rendering, going into detail about Sparse Voxel Octrees ray casting. It gives a good overview on how to tackle the problem of...

Ray / Octree traversal
Since the basic work on my voxel raycaster is finished (Crunching voxels with 3D DDA – generalized Bresenham – in a 3D array), it’s time to start looking at hierarchical structures and the methods of...

Octree Data Structures
After some days of tweaking my SVO renderer’s performance, it became clear that I needed a more cache-coherent and space-efficient way of storing/accessing the octree data. I decided to start a...

Introducing Moctree and Binvox2Moctree
During my PhD work, I’ve ran into a lot of practical issues with constructing and traversing sparse voxel Octrees. I’m introducing a new file format to store them, based on the .binvox file format by...

Voxel Raycaster: Progress report
After a few weeks of optimizing and getting a lot of good C++ advice from Ares Lagae, I consider my CPU-based voxel raycaster as done. I now have a good framework to test some more interesting stuff...

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...

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...
View ArticleOut-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...

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...
