A comprehensive physical model for light reflection
TLDR
A new general reflectance model for computer graphics is presented and provides a smooth transition from diffuse-like to specular reflection as the wavelength and incidence angle are increased or the surface roughness is decreased.
Instant architecture
TLDR
A new method for the automatic modeling of architecture using split grammars, a new type of parametric set grammar based on the concept of shape, which offers the flexibility required to model buildings using a large variety of different styles and design ideas.
Radiosity and global illumination
TLDR
The authors reformulate some of the most recent and innovative research results into a consistent framework, allowing readers to quickly acquire a comprehensive view of the radiosity technique and its derivatives.
Fast calculation of soft shadow textures using convolution
TLDR
A hierarchical, error driven algorithm for fast shadow calculation in arbitrary configurations using a hierarchy of object clusters is derived and results are demonstrated, showing that soft shadows can be generated at interactive rates for dynamics environments.
A frequency analysis of light transport
TLDR
The frequency content of radiance and how it is altered by phenomena such as shading, occlusion, and transport is studied and predictions on the frequency content can then be used to control sampling rates for rendering.
Billboard clouds for extreme model simplification
TLDR
This work introduces billboard clouds -- a new approach for extreme simplification in the context of real-time rendering that combines the strengths of mesh decimation and image-based impostors.
Capture of hair geometry from multiple images
TLDR
An image-based approach to capture the geometry of hair by drawing information from the scattering properties of the hair that are normally considered a hindrance and paves the way for a new approach to digital hair generation.
Accurate detection of symmetries in 3D shapes
TLDR
Applications of this work range from coherent remeshing of geometry with respect to the symmetries of a shape to geometric compression, intelligent mesh editing, and automatic instantiation.

TLDR
It is shown that the accurate distribution of the energy emitted or received at the cluster level can produce even better results than isotropic clustering at a marginal cost.
Conservative volumetric visibility with occluder fusion
TLDR
This paper introduces a new approach to the computation of volume visibility, the detection of occluded portions of space as seen from a given region, and is the first one to use the property that occluders can also be extended into empty space provided this space is itself occluding from the viewing volume.
