VIZARD - Visualization Accelerator for Realtime Display
(The Eurographics Association, 1997)
Volume rendering has traditionally been an application for supercomputers, workstation networks or expensive special-purpose hardware. In contrast, this report shows how far we have reached using the other extreme: the ...
Memory Access Patterns of Occlusion-Compatible 3D Image Warping
(The Eurographics Association, 1997)
McMillan and Bishop s 3D image warp can be efficiently implemented by exploiting the coherency of its memory accesses. We analyze this coherency, and present algorithms that take advantage of it. These algorithms traverse ...
Codesign Of Graphics Hardware Accelerators
(The Eurographics Association, 1997)
The design of a hardware architecture for a computer graphics pipeline requires a thorough understanding of the algorithms involved at each stage, and the implications these algorithms have on the organisation of the ...
Architectural Implications of Hardware-Accelerated Bucket Rendering on the PC
(The Eurographics Association, 1997)
Bucket rendering is a technique whereby a scene is sorted into screen-space tiles and each tile is rendered independently in turn. We expect hardware-accelerated bucket rendering to become available on the PC, and in this ...
Towards Real-Time Photorealistic Rendering: Challenges and Solutions
(The Eurographics Association, 1997)
A growing number of real-time applications need graphics with photorealistic quality, especially in the field of training (virtual operation, driving and flightsimulation), but also in the areas of design or ergonomic ...
EM-Cube: An Architecture for Low-Cost Real-Time Volume Rendering
(The Eurographics Association, 1997)
EM-Cube is a VLSI architecture for low-cost, high quality volume rendering at full video frame rates. Derived from the Cube4 architecture developed at SUNY at Stony Brook, EM-Cube computes sample points and gradients ...
Realizing OpenGL: Two Implementations of One Architecture
(The Eurographics Association, 1997)
The OpenGL Graphics System provides a well-specified, widely accepted dataflow for 3D graphics and imaging. OpenGL is an architecture; an OpenGL-capable computer is a hardware manifestation or implementaion of that ...
PixelFlow: The Realization
(The Eurographics Association, 1997)
PixelFlow is an architecture for high-speed, highly realistic image generation, based on the techniques of object-parallelism and image composition. Its initial architecture was described in [MOLN92]. After development by ...
Triangle Scan Conversion using 2D Homogeneous Coordinates
(The Eurographics Association, 1997)
We present a new triangle scan conversion algorithm that works entirely in homogeneous coordinates. By using homogeneous coordinates, the algorithm avoids costly clipping tests which make pipelining or hardware implementations ...
