Over the years, there have been two main branches of computer graphics image-synthesis
research; one focused on interactivity, the other on image quality. Procedural shading is a …

One of the main techniques used by software renderers to produce stunningly realistic
images is programmable shading—executing an arbitrarily complex program to compute the …

Programmable shading is a common technique for production animation, but interactive
programmable shading is not yet widely available. We support interactive programmable …

Real-time graphics hardware is becoming programmable, but this programmable hardware
is complex and difficult to use given current APIs. Higher-level abstractions would both …

This book covers real-time shading systems, their design and how they work. Procedural
shading, long valued for off-line rendering and production animation is now possible on …

Modern graphics accelerators have embedded programmable components in the form of
vertex and fragment shading units. Current APIs permit specification of the programs for …

Techniques usually consider non-interactive a few years ago are now possible in real-time
using the flexibility and speed of new programmable graphics hardware. An example of that …

Computer image generation systems often represent curved surfaces as a mesh of planar
polygons that are shaded to restore a smooth appearance. Phong shading is a well known …

A shading language provides a means to extend the shading and lighting formulae used by
a rendering system. This paper discusses the design of a new shading language based on …

Extensions to the texture-mapping support of the abstract graphics hardware pipeline and
the OpenGL API are proposed to better support programmable shading, with a unified …
