Continuous shading of curved surfaces

TLDR
The surface is approximated by small polygons in order to solve easily the hidden-parts problem, but the shading of each polygon is computed so that discontinuities of shade are eliminated across the surface and a smooth appearance is obtained.Abstract:
A procedure for computing shaded pictures of curved surfaces is presented. The surface is approximated by small polygons in order to solve easily the hidden-parts problem, but the shading of each polygon is computed so that discontinuities of shade are eliminated across the surface and a smooth appearance is obtained. In order to achieve speed efficiency, the technique developed by Watkins is used which makes possible a hardware implementation of this algorithm.read more

A progressive refinement approach to fast radiosity image generation
TL;DR: A reformulated radiosity algorithm is presented that produces initial images in time linear to the number of patches, which brings the use of radiosity for interactive rendering within reach and has implications for the use and development of current and future graphics workstations.

The haptic display of complex graphical environments
TL;DR: This work has developed a haptic rendering system that allows for the efficient tactile display of graphical information and uses a common high-level framework to model contact constraints, surface shading, friction and tex ture.

ARTS: accelerated ray-tracing system
TL;DR: After investigating both simple spatial enumeration and a hybrid octree approach, 3DDDA is developed, a 3D line generator for efficient traversing of both structures and provides an order of magnitude improvement in processing speed compared to other known ray-tracing methods.
