	Harmonic Coordinates for Character Articulation Pushkar Joshi, Mark Meyer, Tony DeRose, Brian Green, Tom Sanocki May 2007 In this paper we consider the problem of creating and controlling volume deformations used to articulate characters for use in high-end applications such as computer generated feature films. We introduce a method we call harmonic coordinates that significantly improves upon existing volume deformation techniques. Our deformations are controlled using a topologically flexible structure, called a cage, ...

	Key Point Subspace Acceleration and Soft Caching Mark Meyer, John Anderson May 2007 Many applications in Computer Graphics contain computationally expensive calculations. These calculations are often performed at many points to produce a full solution, even though the subspace of reasonable solutions may be of a relatively low dimension. The calculation of facial articulation and rendering of scenes with global illumination are two example applications that ...

	Statistical Acceleration for Animated Global Illumination Mark Meyer, John Anderson January 2006 Global illumination provides important visual cues to an animation, however its computational expense limits its use in practice. In this paper, we present an easy to implement technique for accelerating the computation of indirect illumination for an animated sequence using stochastic ray tracing. We begin by computing a quick but noisy solution using a ... [more] Additional materials: [ShotRender.mov] To appear in SIGGRAPH 2006 Available as Pixar Technical Memo #06-03
