Stereohaptics: a haptic interaction toolkit for tangible virtual experiences (2016)
Presentation / Conference Contribution
Israr, A., Zhao, S., McIntosh, K., Schwemler, Z., Fritz, A., Mars, J., Bedford, J., Frisson, C., Huerta, I., Kosek, M., Koniaris, B., & Mitchell, K. (2016, July). Stereohaptics: a haptic interaction toolkit for tangible virtual experiences. Presented at ACM SIGGRAPH 2016 Studio on - SIGGRAPH '16, Anaheim, CA, US

With a recent rise in the availability of affordable head mounted gear sets, various sensory stimulations (e.g., visual, auditory and haptics) are integrated to provide seamlessly embodied virtual experience in areas such as education, entertainment,...

User, metric, and computational evaluation of foveated rendering methods (2016)
Presentation / Conference Contribution
Swafford, N. T., Iglesias-Guitian, J. A., Koniaris, C., Moon, B., Cosker, D., & Mitchell, K. (2016, July). User, metric, and computational evaluation of foveated rendering methods. Presented at Proceedings of the ACM Symposium on Applied Perception - SAP '16

Perceptually lossless foveated rendering methods exploit human perception by selectively rendering at different quality levels based on eye gaze (at a lower computational cost) while still maintaining the user's perception of a full quality render. W... Read More about User, metric, and computational evaluation of foveated rendering methods.

Simulation and skinning of heterogeneous texture detail deformation (2016)
Patent
Koniaris, C., Mitchell, K., & Cosker, D. (2016). Simulation and skinning of heterogeneous texture detail deformation. US2016133040

A method is disclosed for reducing distortions introduced by deformation of a surface with an existing parameterization. In an exemplary embodiment, the method comprises receiving a rest pose mesh comprising a plurality of faces, a rigidity map corre...

Real-time variable rigidity texture mapping (2015)
Presentation / Conference Contribution
Koniaris, C., Mitchell, K., & Cosker, D. (2015, November). Real-time variable rigidity texture mapping. Presented at Proceedings of the 12th European Conference on Visual Media Production - CVMP '15

Parameterisation of models is typically generated for a single pose, the rest pose. When a model deforms, its parameterisation characteristics change, leading to distortions in the appearance of texture-mapped mesostructure. Such distortions are unde...

Guided ecological simulation for artistic editing of plant distributions in natural scenes (2015)
Journal Article
Bradbury, G. A., Subr, K., Koniaris, C., Mitchell, K., & Weyrich, T. (2015). Guided ecological simulation for artistic editing of plant distributions in natural scenes. The Journal of Computer Graphics Techniques, 4(4), 28-53

In this paper we present a novel approach to author vegetation cover of large natural scenes. Unlike stochastic scatter-instancing tools for plant placement (such as multi-class blue noise generators), we use a simulation based on ecological processe...

Content aware texture mapping on deformable surfaces (2014)
Patent
Koniaris, C., Cosker, D., Yang, X., Mitchell, K., & Matthews, I. (2014). Content aware texture mapping on deformable surfaces. US2014267306

A method is disclosed for reducing distortions introduced by deformation of a surface with an existing parameterization. In one embodiment, the distortions are reduced over a user-specified convex region in texture space ensuring optimization is loca...

Survey of texture mapping techniques for representing and rendering volumetric mesostructure (2014)
Journal Article
Koniaris, B., Cosker, D., Yang, X., & Mitchell, K. (2014). Survey of texture mapping techniques for representing and rendering volumetric mesostructure. The Journal of Computer Graphics Techniques, 3(2), 18-60

Representation and rendering of volumetric mesostructure using texture mapping can potentially allow the display of highly detailed, animated surfaces at a low performance cost. Given the need for consistently more detailed and dynamic worlds rendere... Read More about Survey of texture mapping techniques for representing and rendering volumetric mesostructure.
