Deep Precomputed Radiance Transfer for Deformable Objects (2019)
Presentation / Conference Contribution
Li, Y., Wiedemann, P., & Mitchell, K. (2019, May). Deep Precomputed Radiance Transfer for Deformable Objects. Presented at ACM Symposium on Interactive 3D Graphics and Games, Montreal, Quebec, Canada

We propose, DeepPRT, a deep convolutional neural network to compactly encapsulate the radiance transfer of a freely deformable object for rasterization in real-time.
With pre-computation of radiance transfer (PRT) we can store complex light interac... Read More about Deep Precomputed Radiance Transfer for Deformable Objects.

GPU-accelerated depth codec for real-time, high-quality light field reconstruction (2018)
Journal Article
Koniaris, B., Kosek, M., Sinclair, D., & Mitchell, K. (2018). GPU-accelerated depth codec for real-time, high-quality light field reconstruction. Proceedings of the ACM on Computer Graphics and Interactive Techniques, 1(1), 1-15. https://doi.org/10.1145/3203193

Pre-calculated depth information is essential for efficient light field video rendering, due to the prohibitive cost of depth estimation from color when real-time performance is desired. Standard state-of-the-art video codecs fail to satisfy such per... Read More about GPU-accelerated depth codec for real-time, high-quality light field reconstruction.

Empowerment and embodiment for collaborative mixed reality systems: Empowerment and Embodiment (2018)
Journal Article
Pan, Y., Sinclair, D., & Mitchell, K. (2018). Empowerment and embodiment for collaborative mixed reality systems: Empowerment and Embodiment. Computer Animation and Virtual Worlds, 29(3-4), https://doi.org/10.1002/cav.1838

We present several mixed‐reality‐based remote collaboration settings by using consumer head‐mounted displays. We investigated how two people are able to work together in these settings. We found that the person in the AR system will be regarded as th... Read More about Empowerment and embodiment for collaborative mixed reality systems: Empowerment and Embodiment.

Compressed Animated Light Fields with Real-time View-dependent Reconstruction (2018)
Journal Article
Koniaris, C., Kosek, M., Sinclair, D., & Mitchell, K. (2019). Compressed Animated Light Fields with Real-time View-dependent Reconstruction. IEEE Transactions on Visualization and Computer Graphics, 25(4), 1666-1680. https://doi.org/10.1109/tvcg.2018.2818156

We propose an end-to-end solution for presenting movie quality animated graphics to the user while still allowing the sense of presence afforded by free viewpoint head motion. By transforming offline rendered movie content into a novel immersive repr... Read More about Compressed Animated Light Fields with Real-time View-dependent Reconstruction.

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.

Capture and analysis of racing gameplay metrics (2011)
Journal Article
Jimenez, E., Mitchell, K., & Seron, F. (2011). Capture and analysis of racing gameplay metrics. IEEE Software, 28, 46-52. https://doi.org/10.1109/MS.2011.71

This article presents a flexible, extendable system called Tracktivity that can capture gameplay metrics in any type of leaderboard-based video game. This system incorporates novel visualizations, including a dynamic competition balancing (DCB) measu... Read More about Capture and analysis of racing gameplay metrics.

The perspective tunnel: An inside view on smoothly integrating detail and context. (1997)
Presentation / Conference Contribution
Mitchell, K., & Kennedy, J. (1997, April). The perspective tunnel: An inside view on smoothly integrating detail and context. Presented at Proc. of Eurographics Workshop on Visualisation in Scientific Computing

The perspective tunnel, a general kind of information visualisation artefact, embodies a visual form which exploits natural human visual perception. Perspective tunnels map information on to the floor, ceiling and walls of a tunnel, so that both ever...

Using active constructs in user-interfaces to object-oriented databases. (1997)
Presentation / Conference Contribution
Mitchell, K., Kennedy, J., & Barclay, P. J. (1997). Using active constructs in user-interfaces to object-oriented databases. In Proceedings [of the First] International database engineering and applications symposium, (3-12)

This paper examines the use of active constructs in the definition of user-interfaces to object-oriented databases. A development environment for user-interfaces to databases is presented which features the interactive use of active features of an ob...

Describing and characterising visualisations. (1996)
Presentation / Conference Contribution
Kennedy, J. B., Mitchell, K. J., & Barclay, P. J. (1996). Describing and characterising visualisations. In 3rd FADIVA Workshop

A generic framework for describing and specifying interfaces to databases has been proposed [1]. Currently this
framework is being used as a model for the development of an environment for the construction of user interfaces to object oriented datab... Read More about Describing and characterising visualisations..

This paper describes a runtime user-interface development
environment (UIDE) for the novel capability of interactively using and specifying user-interfaces to object-oriented databases (IDSs). A framework provides the foundation for IDSs constructed... Read More about DRIVE: An environment for the organised construction of user interfaces to data..

Presentation / Conference Contribution
Mitchell, K., Kennedy, J., & Barclay, P. J. (1996, May). A framework for user-interfaces to databases. Presented at International Workshop on Advanced Visual Interfaces, AVI\'96

A framework for user-interfaces to databases (IDSs) is proposed which draws from existing research on human computer interaction (HCI) and database systems. The framework is described in terms of a classification of the characteristic components of a... Read More about A framework for user-interfaces to databases.

Using a conceptual data language to describe a database and its interface (1995)
Presentation / Conference Contribution
Mitchell, K., Kennedy, J., & Barclay, P. J. (1995, July). Using a conceptual data language to describe a database and its interface. Presented at 13th British National Conference on Database - BNCOD13, 1995, University of Manchester

We propose a conceptual approach to defining interfaces to databases which uses the features of a fully object oriented data language to specify interface objects combined with database objects. This achieves a uniform, natural way of describing data... Read More about Using a conceptual data language to describe a database and its interface.
