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.
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.
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.
