With appropriate hardware, Mac OS X provides a capable platform for real-time 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)
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)
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)
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)
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)
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)
Creating repetitive geometric features such as scales or cobblestones for computer graphics is difficult and tedious to perform manually, particularly for seamless 3D surfaces. However, procedural approaches rarely provide the fine-grained control required for motion picture production. Representation of shape detail does not fit easily into traditional(More)
<i>Legend of the Guardians: The Owls of Ga'Hoole (LotG)</i> features over sixty distinctive, art-directed, hyper-realistic feathered characters. We developed a procedural feathering pipeline, <i>Quill</i>, to efficiently realise more than fifteen unique bird species required by the story. This toolset allows a procedural representation of feathers to be(More)
