Real-time 3D computed tomographic reconstruction using commodity graphics hardware

Physics in Medicine and Biology, 2007
The recent emergence of various types of flat-panel x-ray detectors and C-arm gantries now enables the construction of novel imaging platforms for a wide variety of clinical applications. Many of these applications require interactive 3D image generation, which cannot be satisfied with inexpensive PC-based solutions using the CPU. We present a solution

Van der Waals Surfaces in Molecular Modeling: Implementation with Real-Time Computer Graphics

Science, 1983
A method is described for generating van der Waals molecular surfaces with a real-time interactive calligraphic color display system. These surfaces maintain their proper representation during bond rotation and global transformations, and an interior atom removal method yields a comprehensible picture of the molecular surface for large molecules.

A shadow generation in real-time computer graphics

Proceedings of the 1996 IEEE IECON. 22nd International Conference on Industrial Electronics, Control, and Instrumentation, 2002
This paper proposes a new algorithm for real-time shadow generation of a large gaming area, such as for flight simulators. A shadow generation should be improved for the reality of imagery, but its real-time implementation demands the large amount of hardware and the shortage of precision of fixed point calculation is easy to cause false shadow. Shadow

Interactive-adaptive, large displacement analysis with real-time computer graphics

Computers & Structures, 1983
Abstract This paper presents an investigation of interactive-adaptive techniques for large displacement analysis of frames based on vector refresh graphic terminals and 32-bit, virtual-memory, minicomputers. The first aspect of this investigation is a review of interactive graphics techniques to monitor results and control the flow of the analysis ...

A Real-Time Stereoscopic Small-Computer Graphics Display System

IEEE Transactions on Systems, Man, and Cybernetics, 1975
A brief review of the principles of stereoscopy is given followed by a discussion of candidate methods for providing stereoscopic viewing of display data. An analog computer implementation of a stereoscopic graphics display system is described.

DYNAMIC FRACTURING OF 3D MODELS FOR REAL TIME COMPUTER GRAPHICS

2018 - 3DTV-Conference: The True Vision - Capture, Transmission and Display of 3D Video (3DTV-CON), 2018
This work proposes a method of fracturing one-sided 3D objects, in real time, using standard GPU shaders. Existing implementations include either pre-fracturing objects and replacing them at run-time, or precomputing the fracture patterns and using them to fracture the objects depending on user interaction. In this article we describe a novel method in
