We present the first SNN simulator to scale to 8 GPUs, allowing you to simulate larger models and in less time than ever before. Features include:

• State of the art performance (incl. lightning fast setup)
• Ability to define custom models in native C++
• Modern, user-friendly API
• No 3rd-party dependencies (except CUDA)

“Spice” is a state of the art spiking neural network simulator written in C++ and CUDA. It

• is up to 3x faster than the competition,
• allows you to specify your own models through a modern and intuitive API (you simply inherit from a model base class and override callbacks),
• builds out of the box without any 3rd-party dependencies (apart from CUDA), and
• does not involve any proprietary compilation steps or domain-specific languages.

We estimate human poses by treating them as missing/incomplete rows in a “pose database” matrix and calculating missing entries via matrix completion.

KinectFusion is a well-known 3D scanner powered by Microsoft’s Kinect camera. It has recently found its way into the official Kinect for Windows SDK. While KinectFusion produces very high-quality scans in real-time, it is limited to relatively small spaces.

In this paper we extend KinectFusion with a sparse data structure and streaming, allowing us to scan areas of virtually infinite size while maintaining the quality and performance of the original algorithm.

Unpublished BSc thesis

Voxels date back 20 years. They have many advantages over polygon meshes. However, they always suffered form the lack of a hardware-accelerated rendering pipeline and the infeasiblity of animating them. I tackled this age-old computer graphics problem in my BSc thesis. The (GPU-accelerated) animation technique I developed enables:

• Skeletal animation of voxels models
• Rendering of mixed polygon- and voxel-based content.
