Boundary cell-based acceleration for volume ray casting

Computers & Graphics, 1998
Abstract Several effective acceleration techniques for volume rendering offer efficient means to skip over empty space, providing significant speedup without affecting image quality. The effectiveness of such an approach depends on its ability to accurately estimate the object boundary inside a volume with minimal computational overhead. We propose a

Rayfilling: A new method to accelerate ray casting

Computers & Graphics, 1994
Abstract This paper presents a new method for ray casting solid models described by CSG trees. This new approach accelerates image generation by a reduction of the number of rays analysed in search of an intersection with the objects of a scene.

Study and application on accelerated algorithm of ray-casting

SPIE Proceedings, 2007
Medical image 3D reconstruct is an important application filed for volume rendering, for it special using, it required fast interactive speed and high image quality. The ray casting algorithm (RCA) is a widely used basic volume rendering algorithm. It can get high quality image but the rendering speed is very slowly for powerful computing capacity ...

Accelerated Forming on the Sol-Silicate Binder in Precision Casting

Solid State Phenomena, 2018
As a result of the research, the technology of accelerated forming on the sol-silicate binder in precision casting has been developed. It is based on granular materials cladding by the gel-processing catalysts of the sol-silicate binder and on the use of the clad granular materials as the stucco of ceramic coating layers.
