Our project Adaptive Image-Space Sampling for Gaze-Contingent Real-time Rendering won the “Best Paper Award” at the Eurographics Symposium on Rendering (EGSR) conference 2016 in Dublin, Ireland.

We presented an algorithm to reduce the shading costs in high-resolution, high-field of view setups, such as head mounted displays for virtual reality. The algorithm selects a subsample set of pixels to shade and efficiently interpolates the radiance information for the rest of the image.

Congratulations to Michael Stengel and all co-authors.

Our work “Adaptive Image-Space Sampling for Gaze-Contingent Real-time Rendering” has been accepted at EGSR 2016 and will be presented on Friday 24th of June.

Abstract:

With ever-increasing display resolution for wide field-of-view displays – such as head-mounted displays or 8k projectors – shading has become the major computational cost in rasterization. To reduce computational effort, we propose an algorithm that only shades visible features of the image while cost-effectively interpolating the remaining features without affecting perceived quality. In contrast to previous approaches we do not only simulate acuity falloff but also introduce a sampling scheme that incorporates multiple aspects of the human visual system: acuity, eye motion, contrast (stemming from geometry, material or lighting properties), and brightness adaptation. Our sampling scheme is incorporated into a deferred shading pipeline to shade the image’s perceptually relevant fragments while a pull-push algorithm interpolates the radiance for the rest of the image. Our approach does not impose any restrictions on the performed shading. We conduct a number of psycho-visual experiments to validate scene- and task-independence of our approach. The number of fragments that need to be shaded is reduced by 50 % to 80 %. Our algorithm scales favorably with increasing resolution and field-of-view, rendering it well-suited for head-mounted displays and wide-field-of-view projection.

I offer the following courses in the upcoming SS 2016, for more details click on “Teaching” or take a look at the HOPS system:

• Computergrafik und Animation 2 (WPF for bachelor students of MI and AI)

  • The course will investigate advanced CG algorithms and data structures
  • The course will be given as a block course from 29.03.-01.04.2016

• 3D Movie Production in Theory and Practice (WPF for MMI)

  • A look behind the scenes and algorithms of 3D movie production, you will also produce your own during the course

• Visualistik (mandatory for MMI)

  • Learn why visualizations can be so intriguing or why not and build your own to present your data to others

• Theoretische Informatik 2 (mandatory for MI and AI)

  • It seems we can do anything with our computers, but is this really true?

Our project Visibility sweeps for joint-hierarchical importance sampling of direct lighting for stochastic volume rendering won the “Best Student Paper Award” at the Graphics Interface conference 2015 in Halifax, Nova Scotia, Canada.

We presented a visibility estimation method in concert with an importance-sampling technique for efficient and unbiased stochastic volume rendering. Our solution relies on a joint strategy, which involves the environmental illumination and visibility inside of the volume.

Congratulations to Thomas Kroes and all co-authors.

Our project An Affordable Solution for Binocular Eye Tracking and Calibration in Head-mounted Displays won the “Best Student Paper Award” at the ACM Multimedia Conference 2015 in Brisbane, Australia.

We presented an integrated eye-tracking solution for a personalizable head-mounted display for virtual reality applications. The system is a low-cost solution without limiting the field-of-view. Freely adjustable lenses reduce motion sickness.

Congratulation to Michael Stengel and all co-authors.
