Three-dimensional computer graphics architecture

Three-dimensional (3D) computer graphics hardware has emerged as an integral part of mainstream desktop PC systems. The aim of this paper is to describe the 3D graphics architecture at a level accessible to the general computational science community. We start with the generic 3D graphics rendering algorithm, the computational requirements of each of its steps, and the basic architectural featu...

An Image-based Approach to Three-dimensional Computer Graphics

A Portable 3-Dimensional Digitizer for Computer Graphics 3D Modeling

This project created a portable three-dimensional digitizer for computer graphics 3D modeling. It started from reviewing literature then constructed a digitizer, developed applications programs, created experiments and analyzed. The process of the machine started from reading pulse train of the arm rotation via Rotary Encoder at each joint. Next, it was processed by microcontroller and sent the...

Three-Dimensional Image Warping on Programmable Graphics Hardware

Many image-based rendering systems are based on three-dimensional image warping (3D Warping), which transforms pixels in reference image to destination view. However, the original 3D warping equation, proposed by McMillan and Bishop, is derived under one special coordinate system, making its inability of direct implementation on programmable graphics hardware. In this paper, we revisit the 3D w...

Two and Three-Dimensional Image Deconvolution on Graphics Hardware

The process of image formation in an optical microscope or similar imaging device results in a distortion of the true object image due to diffraction effects and out-of-focus blurring. This distortion can greatly limit the resolution of the imaging device, particularly in the case of 3D microscopy where the axial resolution is impeded by the contribution of out-of-focus signal from an extended ...
