Intersection-free mesh decimation for high resolution cloth models

We present an approach to reduce high-resolution polygonal clothing meshes for Mixed Reality (VR/AR) scenarios. Due to hardware limitations, current mobile devices require 3D models with a strongly reduced triangle count to be displayed smoothly. A particular challenge for mesh reduction of clothing models is that these models usually consist of several fabric layers, which are spatially tightly together, touching in many places.

An Atlas-Packing Algorithm for Efficient Rendering of Arbitrarily Parametrized Decal Textures

When rendering large amounts of decals, huge overheads can considerably reduce performance, which is especially harmful for critical applications such as virtual reality. To reduce these overheads, we propose a novel algorithm packing arbitrarily parametrized decal textures into a sparse texture, which is realized via a reference atlas holding the necessary information to access tiles stored in a tile atlas.

Performance of Augmented Reality Remote Rendering via Mobile Network

In this paper, a remote rendering system for an AR app based on Unity is presented. The system was implemented for an edge server, which is located within the network of the mobile network operator.

Accelerated Stereo Rendering with Hybrid Reprojection-Based Rasterization and Adaptive Ray-Tracing

This paper presents a hybrid rendering system that combines classic rasterization and real-time ray-tracing to accelerate stereoscopic rendering. The system reprojects the pre-rendered left half of the stereo image pair into the right perspective using a forward grid warping technique and identifies resulting reprojection errors, which are then efficiently resolved by adaptive real-time ray-tracing.

The influence of different audio representations on linear visually induced self-motion

We investigate the influence of four different audio representations on visually induced self-motion (vection). Our study followed the hypothesis, that the feeling of visually induced vection can be increased by audio sources while lowering negative feelings such as visually induced motion sickness.
