Data subsets represent major entities for distributed rendering and computing.
NVIDIA IndeX decomposes the scene into subregions. In particular the decomposition also subdivides those scene elements that represent large-scale datasets (see Distributed Datasets) into smaller-sized portions. These are called data subsets. Data subsets are contained inside subregions, i.e., each subregion that intersect part of the distributed dataset extent contains one data subset of the distributed dataset. This way, data subsets represent the major entities for data distribution to cluster hosts and
GPUs, for parallel and scalable distributed rendering on GPU clusters and for parallel and scalable distributed data processing.
For instance, the sparse volume dataset ISparse_volume_scene_element will be represented by many ISparse_volume_subset distributed to cluster nodes. Each of the volume's subsets are rendered independently for scalable volume data visualization and each of the subsets may be processed, analysed and manipulated in parallel for scalable and distributed computing.
Data subsets are distributed datatype specific and comprise tailored interfaces for efficient access of the internal type-specific data structures as well as efficient update of the internal data representation of a data subset contained in a subregion. For instance, the interface class ISparse_volume_subset exposes methods for writing new voxel values and thus updating the volume's data. Also, the interace class provides methods for querying the internal brick and level-of-detail structures and attribute descriptions.
