MIME (Mime Is Manual Expression) is a computationally efficient computer vision system for recognizing hand gestures. The system is intended to replace the mouse interface on a standard personal computer to control application software in a more intuitive manner. The system is implemented in C code with no hardware-acceleration and tracks hand motion at 30(More)
Accurate tracking of human movement has the potential to enable many kinds of human-computer interaction (HCI). Vision-based methods promise tracking without encumberance by body-mounted apparatus but constitute a significant research challenge. Its many applications both in HCI and other areas such as surveillance have made markerless human tracking a(More)
With appropriate hardware, Mac OS X provides a capable platform for realtime image processing (RTIP). This paper provides an overview of available video capture hardware and presents development strategies to achieve high performance, low latency image processing. As the requirements of real-time image processing differ significantly to those for video(More)
Volumetric effects have become a mainstay of the visual effects community over the past decade. With many third-party solutions available, what are the benefits and challenges of creating a proprietary system? We outline <i>Snap</i>, Animal Logic's grid-based simulation and volumetric rendering framework used in <i>Legend of the Guardians: The Owls of(More)
In <i>The LEGO Movie</i> everything on screen from characters and sets to oceans and explosions is realised with bricks. By building a brick library we were able to automatically assemble optimized models from XML files output by LEGO Digital Designer. A sophisticated shader and numerous texture variations for each brick were also created, allowing us to(More)
We created an efficient pipeline for automated, HDR light probes for the hybrid live-action / animated feature film <i>Peter Rabbit.</i> A specially developed "360&#176;" spherical camera allows on-set acquisition at more positions and in less time than traditional techniques. Reduced capture time, drastically simplified stitching and a custom(More)
The last few years have seen a decisive move of the movie making industry towards rendering using physically-based methods, mostly implemented in terms of path tracing. While path tracing reached most VFX houses and animation studios at a time when a physically-based approach to rendering and especially material modelling was already firmly established, the(More)
Building the digital sets for <i>Guardians of the Galaxy Vol. 2</i> presented a unique challenge for <i>Animal Logic's</i> asset and FX teams. The creative brief involved two separate alien environments made from complex mathematical shapes, with an unprecedented amount of detail. As an additional challenge the environments had to match the look and feel of(More)
