Computer graphics

The breakthrough of graphics processing hardware (GPU) has brought new development opportunities to many different research fields. Compared with traditional computing units (CPU), GPU has stronger computing power and is more suitable for computing-intensive applications. There are many problems in graphics and vision that are suitable for GPU acceleration. However, due to the GPU and CPU architectures are designed completely differently. Hence, many existing algorithms need to be redesigned to run efficiently on GPUs. Currently the problem faced by parallel geometric computation is to carefully conduct in-depth analysis of the related geometric problems and decompose the tasks into local sub-problems avoiding complex task scheduling and inter-thread communication, thereby achieving a viable solution for GPU parallel processing.
