Hidden contours on a frame-buffer
(The Eurographics Association, 1992)
To comply with drafting practices and because shaded images do not always reveal the internal or hiddenstructures of 3D models, designers need wireframe images with hidden lines dashed and nonconlour tesselation edges ...
Parallelization and Hardware Support for Ray Tracing
(The Eurographics Association, 1992)
Even on the latest workstations ray tracing is still a very time-consuming algorithm.This paper makes a thorough analysis of previous attempts to accelerate raytracing by means of parallelization with general purpose ...
An Efficient Massively Parallel Rasterization Scheme For a High Performance Graphics System
(The Eurographics Association, 1992)
We present in this paper the IMOGENE II system, a massively parallelMulti-SIMD graphics system. This architecture uses a new rasterization scheme combining Object Parallelism and Parallel Virtual Buffers. This scheme leads ...
M-Buffer: A Flexible MISD Architecture for AdvancedGraphics
(The Eurographics Association, 1992)
Contemporary graphics architectures are based on a hardware-supported geometric pipeline, a rasterizer, a z-buffer and two frame buffers. Additional pixel memory isused for alpha blending and for storing logical information. ...
A 2nd generation autostereoscopic 3-D display
(The Eurographics Association, 1992)
On the Design of a Real-Time Volume Rendering Engine
(The Eurographics Association, 1992)
An architecture for a Real-Time Volume Rendering Engine is given capable of computing750x750x512 samples from a 3D dataset at a rate of 25 images per second.The RT-VRE uses for this purpose 64 dedicated rendering chips, ...
An Extended Volume Visualization System for Arbitrary Parallel Projection
(The Eurographics Association, 1992)
We present a special architecture for arbitrary parallel projection for visualization ofvolumetric data. Using a ray-casting technique, parallel memory access, and pipelinedprocessing of rays in a composition tree, we can ...
Depth Complexity in Object-Parallel Graphics Architectures
(The Eurographics Association, 1992)
We consider a multiprocessor graphics architecture object-parallel if graphics primitivesare assigned to processors without regard to screen location, and if each processorcompletely renders the primitives it is assigned. ...
Hardware Challenges for Ray Tracing and Radiosity Algorithms
(The Eurographics Association, 1992)
Computer graphics algorithms and graphics hardware have mainly been developed along two lines: real-time display and realistic display. Real-time display has been achieved by developing dedicated hardware for projective, ...
Accelerating Polygon Clipping
(The Eurographics Association, 1992)
Polygon clipping is a central part of image generation and image visualization systems.In spite of its algorithmic simplicity it consumes a considerable amount of hardware or software resources. Polygon clipping performance ...
