The Witness
Jon has recently started a development blog about The Witness, the game that we have been working on during the last few months. So far there are a few posts ab...

OpenNL 3.0
GPGPU.org takes note that OpenNL 3.0 has just been released and that this new version comes with support for CUDA. That’s certainly interesting, but for me the ...
Continuity Mapping for Multi-Chart Textures
Naty Hoffman references a paper from Siggraph Asia titled Continuity Mapping for Multi-Chart Textures. The paper provides a solution to a problem that I’ve talk...
Efficient Substitutes for Subdivision Surfaces
Our siggraph course has been accepted and is finally up on the siggraph website! Here’s the brief description of the course: An overview of the most recent theo...
NVTT quote
I love this quote from Ivan-Assen Ivanov about the NVIDIA Texture Tools: We switched to CUDA nvcompress in our pipeline and totally forgot about it. Until yeste...
NVIDIA Texture Tools 2.0.6
Yesterday I released another revision of the stable branch of the NVIDIA Texture Tools. I recommend everybody to upgrade, since it fixes some bugs and artifacts...
GPU DXT Decompression
Even thought the DXT compression format is widely adopted, most of the hardware implementations use a slightly different decompression algorithm. The problem is...
Optimal Grid Rendering
This is a trick that I learned from Matthias Wloka during my job interview at NVIDIA. I thought I had a good understanding of the behavior of the vertex post-tr...
ACMR
I think that the Average Cache Miss Ratio (ACMR) is not the best way of measuring the efficiency of the vertex cache under different mesh optimization algorithm...
Real-Time Creased Approximate Subdivision Surfaces
Denis finally put his I3D paper online! Denis was my intern a couple of summers ago. We worked together on the implementation of the an emulation framework to i...
