Automotive Color Design Interfaces
	Computer Aided Design for Color Appearance The BRDF Designer is a tool for manipulating a reflection model for car paint that is based on industry standards for measuring the appearance characteristics of the paint. These measurements include gloss for the clear coat and three or five aspecular measurements for the metallic base coat. The desired measurement of new paint can be input to a paint formulation system so that the paint can be manufactured. Clement Shimizu and Gary Meyer of the University of Minnesota Dave Allman and Allen Rodriguiez of Dupont Allen Eggly of Ford Motor Company
	Virtual Mood Board The virtual mood board is an electronic replacement of a real mood board used for material conception, selection, and communication. A stylist employs the virtual mood board to organize digital images that provide material inspiration, and they use the pictures on the board to seed the parameters of the new metallic reflection model as shown in the upper left image. The colors of the metallic green were selected from this dazzling ad campaign for Christian Dior.

	Sketch Based Material Design In this research we show how surface finish and paint formulations can be extracted from hand painted concept art. A concept artist traces a printout of the object to be styled. Next they use traditional marker and paint techniques to fill in the appearance of the color and surface finish treatment. Inverse rendering techniques are used by the computer graphic system to match the artist's concept color. A paint can be formulated from this match.

	Image Based Appearance Design A special rendering engine was designed to allow for real time material editing when using high dynamic range environment maps. In this image Ford's S Studio was photographically captured using hundreds of photos from various angles and exposures. This environment map is used for interactive design and realistic rendering of automotive paints.

	College for Creative Studies The industrial design department of the College for Creative Studies offers an automotive design course where students design a car from concept art to fully painted clay mockup. The students used the BRDF Design Suite to pick and design colors for their concept vehicles. The colors were formulated and sprayed onto clay models. Clement Shimizu and Gary Meyer of the University of Minnesota The students of the College for Creative Studies
	Adjusting color directly on a 3D object Color stylists often want to make minor modifications to material designs. They may realize that the color needs tweaking only after seeing it on a three dimensional surface like a car. For example, they may want the color on the hood to be a little brighter or the color on the doors to be a little less saturated. Since the object is painted a uniform color, their request must be interpreted as modifications to the spatial aspects of the surface finish reflectance that will affect the entire surface--for example adjusting the rate of iridescence in a metallic effect pigment. This research presents novel color design interfaces for tweaking the color and appearance directly on a 3D object in a simple and intuitive way.

Graphic & Architectural Material Interfaces
	Metallic Foil Logo Designer/Renderer Sarah Steil, a student from DHA, and I partnered to win first prize in a logo redesign contest for the University of Minnesota. Instead of creating a single static logo, we created a whole software workspace for rapid prototyping of metallic foil logo designs. By Clement Shimizu and Sarah Steil
	This is the Color When creating product packaging, the appearance of specialty color treatments, like foils and embossing, is unknown until the design is sent through the printing press. Mistakes are costly, if not impossible, to correct at this stage. A software prototype was created to explore the utility of an Adobe Illustrator plugin to show a realistic preview of specialty foil and gloss spot colors. Clement Shimizu, Sarah Steil, Nicole Steinhofer of the University of Minnesota
	Houminn Practice's Cloak Wall The prototype of the Cloak Wall was exhibited in the Goldstein Museum of Design. The key colors in the color scheme we selected directly from the photograph of the intended site using the BRDF Design Suite and interpolated mathematically. Marc Swackhamer of HouMinn Practice Seth Berrier, Clement Shimizu, and Gary Meyer of the University of Minnesota Allan Rodriguez and David Griffus of DuPont Performance Coatings
	The Wall of Inspiration The Wall of Inspiration was a joint project between the University of Minnesota and Benjamin Moore paints. Customers are often dissatisfied with how different a color looks on a large wall compared to a small color chip. The purpose of the project was to explore the question of electronic color on a large scale display device. By carefully utilizing gloss and BRDF measurements we were able to create a realistic shader that simulated the appearance of paint given the various gloss levels.

Video Art
	Susannah's Mouth Susannah's Mouth was produced for an art party called Dead Sexy 2 at Kingman Studios-known for its wild and hedonistic atmosphere. This video is part of a series of party videos and art installations that focus on a single body part to the point of fetish. By Clement Shimizu Mouth by Susannah Dodge Makeup by Kate Iverson
	Mnartists.org Mashup Hundreds of thousands of art images from tens of thousands of artists were spidered from the mnartists.org site to create a 3D video mashup. The original installation piece was powered by two high resolution projectors that were synchronized to create a high fidelity panoramic display of artwork. The Mnartists.org Mashup video was shown as part of the Festival Appropriation for the duration of the exhibit at the Soap Factory, as well as at the Bakken Museum and the Walker Art Center in the Fall of 2007.

Immersive Projection Systems
	Immersive Projection Systems Typical video projection systems display rectangular images on flat screens. Optical and perspective correction techniques must be employed to produce undistorted output on non-planar display surfaces. A two-pass algorithm, called projective perspective mapping, is implemented in the OmniMap API providing an extensible, reusable C++ interface for porting 3D engines to wide field-of-view, non-planar displays. This allows easy integration into a wide variety of 3D applications. Elumenati's Omnimap and Video Codec have been utilized by a number of organizations including SCISS, Chicago Field Museum, Bose, NASA, NOAA, Cirque du Soleil, Nvidia, and many more. Clement Shimizu and the Elumenati
	Handheld Flexible Display Device A projector with a special spherical lens is combined with a flexible, tracked rear projection screen that users hold in their hands. Unlike normal projectors, the spherical lens allows for a 180 degree field of view and nearly infinite depth of focus. This allows the user to move the screen around the environment and use it as a virtual "slice" to examine the interior of 3D volumes. This provides a concrete correspondence between the virtual representation of the 3D volume and how that volume would actually appear if its real counterpart was sliced open. Jonathan Konieczny, Clement Shimizu, Gary Meyer, and D'nardo Colucci of the University of Minnesota

	Michael Somoroff's Illumination: NYC Matrix Art Collective enlisted The Elumenati to complete the design and installation of a single-channel immersive panoramic installation for artist Michael Somoroff. Called Illumination, it features a downward-facing spherical projector. 270 degree panoramic frames were rendered at very high resolution by Matrix Art Collective. The artist provided a floor plan that included the size and geometry of the screen surface. A custom video player was created to perform a real-time warp of the Super HD video. Although screen-shots of the warp appears extremely distorted, when projected through the spherical lens on the cylindrical screen it appears perspectively correct. Clement Shimizu through Elumenati and Matrix Art Collective for Michael Somoroff
	Cave Art Interactive This interactive exhibit invites visitors to use Wii controllers inside of a dome to explore historians' theories on the origins of Cave Art. The Field Museum's Cave Art Interactive installation won the 2011 Silver MUSE Award, an honor from the Media and Technology arm of the American Association of Museums. The Elumenati produced Cave Art in collaboration with the team at the Field and animator Pat Bradley, as part of the Mammoths and Mastodons exhibit currently touring museums around the country. (Above video was produced by the Field Museum) Clement Shimizu through Elumenati Patrick Bradely Chicago Field Museum and The Elumenati
	Megalodon The Megalodon exhibit at NC Aquarium at Fort Fisher features a L shaped curved screen and interactive touch sensitive shark teeth. The display is powered by a single fisheye projector and the teeth were interfaced with the interactive software using an Arduino.
