abstract = {This paper presents a new interactive rendering and display
technique for complex scenes with expensive shading, such as
global illumination. Our approach combines sparsely sampled
shading (points) and analytically computed discontinuities (edges)
to interactively generate high-quality images. The edge-and-point
image is a new compact representation that combines edges and
points such that fast, table-driven interpolation of pixel shading
from nearby point samples is possible, while respecting
discontinuities. The edge-and-point renderer is extensible,
permitting the use of arbitrary shaders to collect shading
samples. Shading discontinuities, such as silhouettes and shadow
edges, are found at interactive rates. Our software implementation
supports interactive navigation and object manipulation in scenes
that include expensive lighting effects (such as global
illumination) and geometrically complex objects. For interactive
rendering we show that high-quality images of these scenes can be
rendered at 8–14 frames per second on a desktop PC: a speedup of
20–60 over a ray tracer computing a single sample per pixel.},
