For attendees interested in the CG Show of Yoichiro Kawaguchi, an established Japanese CG artist, and those who would like to reunite or socialize with other attendees.

This session may be interesting to those who are building grapics pipelines on Linux and encountering difficulties associated with products, QT versions, python versions, gcc, etc.

Imageworks' parent constraint spXformInterp optimally blends multiple transformations while correctly handling the shear induced when rotation is followed by non-uniform scale, and it can do so in an arbitrary space. This is particularly important with forward/inverse kinematics and motion capture, where several redundant skeletons and multiple constraints would otherwise be needed.

This technique renders texture-seam-free meshes without unwrapping the model into UV space at interactive frame rates.

An overview of the state of CG in Asia, including the evolution of SIGGRAPH Asia. The Chair of SIGGRAPH Asia 2011 summarizes the upcoming conference in December in Hong Kong.

Tracing Home participating artists casually explain and discuss their works, process, and ideas . These talks are followed by short Q & A sessions and an opportunity to meet and chat with the artists. All talks are presented in the Art Gallery.

A metric for predicting visible differences (discrimination) and image quality (MOS) in high-dynamic-range images. The metric is based on new contrast sensitivity measurements and calibrated against several datasets. The visibility predictions are shown to be improved compared to the original HDR-VDP and VDP metrics.

An optical architecture for HDR imaging that allows simultaneous capture of high-, medium-, and low-exposure images, and an HDR merging algorithm that avoids undesired artifacts. This paper explains implementation of a prototype HDR-video system and present sresults from the acquired HDR video.

A perceptually based algorithm for modeling the color shift that occurs for human viewers in low-light scenes. Known as the Purkinje effect, this color shift occurs as the eye transitions from photopic, cone-mediated vision in well-lit scenes to scotopic, rod-mediated vision in dark scenes.

Changing the color of an object is a basic image-editing operation, but a high-quality result must also preserve natural shading. This approach decomposes illumination into direct lighting and indirect illumination from individual materials to consistently modify material colors and their associated interreflections.
