Poxels: polygonal voxel environment rendering (2014)
Presentation / Conference Contribution
Miller, M., Cumming, A., Chalmers, K., Kenwright, B., & Mitchell, K. (2014, November). Poxels: polygonal voxel environment rendering. Presented at Proceedings of the 20th ACM Symposium on Virtual Reality Software and Technology - VRST '14

We present efficient rendering of opaque, sparse, voxel environments with data amplified in local graphics memory with stream-out from a geomery shader to a cached vertex buffer pool. We show that our Poxel rendering primitive aligns with optimized r... Read More about Poxels: polygonal voxel environment rendering.

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...

Error analysis of estimators that use combinations of stochastic sampling strategies for direct illumination (2014)
Journal Article
Subr, K., Nowrouzezahrai, D., Jarosz, W., Kautz, J., & Mitchell, K. (2014). Error analysis of estimators that use combinations of stochastic sampling strategies for direct illumination. Computer Graphics Forum, 33(4), 93-102. https://doi.org/10.1111/cgf.12416

We present a theoretical analysis of error of combinations of Monte Carlo estimators used in image synthesis. Importance sampling and multiple importance sampling are popular variance-reduction strategies. Unfortunately, neither strategy improves the...

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.
