Ray tracing method for stereo image synthesis using CUDA

This paper presents a realization of the approach to spatial 3D stereo of visualization of 3D images with use parallel Graphics processing unit (GPU). The experiments of realization of synthesis of images of a 3D stage by a method of trace of beams on GPU with Compute Unified Device Architecture (CUDA) have shown that 60 % of the time is spent for the decision of a computing problem approximately, the major part of time (40 %) is spent for transfer of data between the central processing unit and GPU for computations and the organization process of visualization. The study of the influence of increase in the size of the GPU network at the speed of computations showed importance of the correct task of structure of formation of the parallel computer network and general mechanism of parallelization. Keywords: Volumetric 3D visualization, stereo 3D visualization, ray tracing, parallel computing on GPU, CUDA

Generalized 3D Voxel Image Synthesis Architecture for Volumetric Spatial Visualization

A general concept of 3D volumetric visualization systems is described based on 3D discrete voxel scenes (worlds) representation. Definitions of 3D discrete voxel scene (world) basic elements and main steps of the image synthesis algorithm are formulated. An algorithm for solving the problem of the voxelized world 3D image synthesis, intended for the systems of volumetric spatial visualization, is proposed. A computer-based architecture for 3D volumetric visualization of 3D discrete voxel world is presented. On the basis of the proposed overall concept of discrete voxel representation, the proposed architecture successfully adapts the ray tracing technique for the synthesis of 3D volumetric images. Since it is algorithmically simple and effectively supports parallelism, it can efficiently be implemented. Key words:Volumetric spatial visualization, 3D volumetric imagesynthesis, discrete voxel world, ray tracing.
