Online view sampling for estimating depth from light fields (2015)
Presentation / Conference Contribution
Kim, C., Subr, K., Mitchell, K., Sorkine-Hornung, A., & Gross, M. (2015, September). Online view sampling for estimating depth from light fields. Presented at 2015 IEEE International Conference on Image Processing (ICIP)

Geometric information such as depth obtained from light fields
finds more applications recently. Where and how to sample
images to populate a light field is an important problem to
maximize the usability of information gathered for depth reconstru... Read More about Online view sampling for estimating depth from light fields.

Latency aware foveated rendering in unreal engine 4 (2015)
Presentation / Conference Contribution
Swafford, N. T., Cosker, D., & Mitchell, K. (2015, November). Latency aware foveated rendering in unreal engine 4. Presented at Proceedings of the 12th European Conference on Visual Media Production - CVMP '15

We contribute a foveated rendering implementation in Unreal Engine 4 (UE4) and a straight-forward metric to allow calculation of rendered foveal region sizes to compensate for overall system latency and maintain perceptual losslessness. Our system de... Read More about Latency aware foveated rendering in unreal engine 4.

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...

Carpet unrolling for character control on uneven terrain (2015)
Presentation / Conference Contribution
Miller, M., Holden, D., Al-Ashqar, R., Dubach, C., Mitchell, K., & Komura, T. (2015, November). Carpet unrolling for character control on uneven terrain. Presented at MIG '15 Proceedings of the 8th ACM SIGGRAPH Conference on Motion in Games

We propose a type of relationship descriptor based on carpet unrolling that computes the joint positions of a character based on the sum of relative vectors originating from a local coordinate system embedded on the surface of a carpet. Given a terra... Read More about Carpet unrolling for character control on uneven terrain.

Augmented creativity: bridging the real and virtual worlds to enhance creative play (2015)
Presentation / Conference Contribution
Zünd, F., Ryffel, M., Magnenat, S., Marra, A., Nitti, M., Kapadia, M., Noris, G., Mitchell, K., Gross, M., & Sumner, R. W. (2015, November). Augmented creativity: bridging the real and virtual worlds to enhance creative play. Presented at SIGGRAPH ASIA 2015 Mobile Graphics and Interactive Applications on - SA '15

Augmented Reality (AR) holds unique and promising potential to bridge between real-world activities and digital experiences, allowing users to engage their imagination and boost their creativity. We propose the concept of Augmented Creativity as empl... Read More about Augmented creativity: bridging the real and virtual worlds to enhance creative play.

Adaptive rendering with linear predictions (2015)
Journal Article
Moon, B., Iglesias-Guitian, J. A., Yoon, S.-E., & Mitchell, K. (2015). Adaptive rendering with linear predictions. ACM transactions on graphics, 34(4), 121:1-121:11. https://doi.org/10.1145/2766992

We propose a new adaptive rendering algorithm that enhances the
performance of Monte Carlo ray tracing by reducing the noise, i.e.,
variance, while preserving a variety of high-frequency edges in rendered
images through a novel prediction based re... Read More about Adaptive rendering with linear predictions.
