This meeting is for studio instructors and industry advisors associated with the NSF CreativeIT research project, Collaborative Undergraduate Computing Studios Facilitating Decentralized Participation.

There are strong indications that the future of interactive graphics programming is a more flexible model than today’s OpenGL/Direct3D pipelines. Graphics developers need to have a basic understanding of how to combine emerging parallel programming techniques and more flexible graphics processors with the traditional interactive-rendering pipeline.

As the first in a series, this course introduces trends and directions in this emerging field: parallel graphics architectures, parallel programming models for graphics, and how game developers are investigating the use of these new capabilities in future rendering engines.

This talk presents a system for capturing and stitching gigapixel-scale time-lapse imagery, and for exploring the resulting gigapixel-scale video in four dimensions: 2D translation, zoom, and time. Topics include algorithms for synthesis of gigapixel-scale video, server and client architectures that allow scalable real-time exploration via the web, gigapixel-scale time-lapse videos, and a breadth of applications.

This XVJ session imagines the future of gesturally expressive video-jockeying. It goes beyond knobs and sliders to experiment with I-CubeX sensors, controllers, and input devices that capture more human movements to control audio-visual effects in real time, using Resolume and Live.

This paper presents:

• A novel spatio-temporal anti-aliasing algorithm with essentially noise-free results. Visibility is solved for along line samples in screen space and in time.
• A new method for ambient occlusion based on line samples/ The method can also handle motion-blurred ambient occlusion.

A new frequency analysis and sheared filter for computing shadows cast by complex occluders. The approach uses ray tracing to sparsely sample the scene and a sheared 4D filter to share shadow samples between neighboring pixels.

In this paper, a method for reconstructing high-quality images from sparse stochastic samples is applied to simultaneous motion blur, depth of field, and soft shadows.

This paper introduces a homogeneous transform that reduces the computation required to determine the set of points or primitives inside a tetrahedral volume. It describes how application of this transform can improve the efficiency of soft shadows and defocus blur computations.

A method to align locally detected RANSAC primitives using global relations, which are learned and conformed to using a combination of graph reduction and constrained optimization. The paper demonstrates applications on synthetic and scanned data, even under structured noise and anisotropic sampling.

The articulated global registration algorithm presented in this work aligns multiple range scans simultaneously to reconstruct a full poseable 3D model. Solving for surface motion using linear-blend skinning and automatically modeled joints allows users to interactively manipulate the resulting 3D model and create new animations.

In this lobe-based tree representation for modeling trees, the tree’s foliage is abstracted into compact canonical geometry structures, called lobe-textures. The method introduces techniques to encode a given tree as lobe-based representation and decode the representation and synthesize a fully detailed tree model.

With this ℓ1-sparse reconstruction of piecewise smooth objects, common objects can be characterized by a small number of features that introduce sparsity into the model. The reconstruction gives rise to shapes that consist mainly of smooth modes, with the objective function residual concentrated near sharp features.

This summary of all the 3D features in Photoshop CS5 Extended demonstrates key 3D workflows that are important for every designer. Topics include: how 3D works in Photoshop (lights, cameras, materials, extrusions) and cool effects like depth of field, animations, image-based lights, and more!

Ornament has been abolished by the avant-garde, and ornamentation has been replaced by material aesthetic. This talk argues that ornament is not a parergon, an unnecessary accessory, but that the parergon, the ornament, actually becomes the ergon, the main element.

Founded in the Netherlands in 1990, ISEA International Foundation (formerly Inter-Society for the Electronic Arts) is an international nonprofit organization fostering interdisciplinary academic discourse and exchange among culturally diverse organizations and individuals working with art, science, and technology. The main activity of ISEA International is the annual International Symposium on Electronic Art. Selection of ISEA symposia is made by the ISEA International Foundation Board.

This discussion includes information about the organization, the upcoming ISEA2012 Albuquerque: Machine Wilderness, a symposium and series of events exploring the discourse of global proportions on the subject of art, technology, and nature. It also previews ISEA2013, in Sydney, Australia. All interested members of the electronic arts community are invited to learn about the future symposia and share ideas for potential organizational collaborations.

Did you ever dream of having your fashion design on a body of your own creation walking the fashion runway? In this class, which uses the Digital Clothing Suite software, human character and pattern data are given to the attendees so that they can learn how to seam patterns, simulate draping of the garment on a walking model, apply and manipulate different images to generate their own textile design, and save the final result into an animation clip. Your clips will be shown in The Studio during the conference. Conference attendees will vote on their favorite designs and the best designer will be awarded a six month free trial of the Digital Clothing Suite at the end of the conference. Participants are welcome to bring images/graphics to use for their custom textile design and to save their work on a flash drive to take home with them.
