The visual appearance of an object can be disguised by projecting virtual shading as if
overwriting the material. However, conventional projection-mapping methods depend on …

Temporal coherence has the potential to enable a huge reduction of shading costs in
rendering. Existing techniques focus either only on spatial shading reuse or cannot …

Recent research on the human visual system shows that our perception of object shape
relies in part on compression and stretching of the reflected lighting environment onto its …

About a year ago, we decided to invest some time in improving our shading model and
embrace a more physically based material workflow. This was driven partly by a desire to …

Recent progress in non-photorealistic rendering (NPR) has led to many stylized shading
techniques that efficiently convey visual information about the objects depicted. Another …

In this chapter, we present distance mapping, a technique for adding small-scale
displacement mapping to objects in a pixel shader. We treat displacement mapping as a ray …

We present AppGen, an interactive system for modeling materials from a single image.
Given a texture image of a nearly planar surface lit with directional lighting, our system …

While traditional graphics techniques provide for the realistic display of three-dimensional
objects, these methods often lack the flexibility to emulate expressive effects found in the …

Shape depiction in non-photorealistic rendering of 3D objects has mainly been concerned
with the extraction of contour lines, which are generally detected by tracking the …

We present an approach to example-based stylization of 3D renderings that better preserves
the rich expressiveness of hand-created artwork. Unlike previous techniques, which are …
