A Rendering Method for V-DMC Encoded Content

The video-based dynamic mesh coding standard is built on the concepts of mesh decimation to form a base-mesh, subdivision surfaces, displacement data, and a lifting transform. The displacement data describes how higher level of detail geometry can be reconstructed from the subdivided base-mesh. It is hierarchically predicted through each subdivision iteration and then coded using traditional 2D video codecs or arithmetically.Because the base-mesh is smaller in size, it allows for faster decoding and transfer from CPU to GPU. Applications should therefore perform the V-DMC reconstruction process on the GPU to take advantage of this.Currently, the standard specifies a step-by-step iterative reconstruction process, but this is not optimized for real-time rendering. In this paper, we describe a rendering method for V-DMC compressed mesh sequences that enables tessellation-based reconstruction of the base-mesh.
