Jan Kautz "Interactive Editing and Modeling of
Bidirectional Texture Functions" Friday 14th March 2008, 2-3pm GMT
Room 1.10,
While measured Bidirectional Texture Functions (BTFs)
enable impressive realism in material appearance, they offer little control,
which limits their use for content creation. In this work, we interactively
manipulate BTFs and create new BTFs from flat textures. We present an
out-of-core approach to manage the size of BTFs and introduce new editing
operations that modify the appearance of a material. These tools achieve their
full potential when selectively applied to subsets of the BTF through the use of
new selection operators. We further analyze the use of our editing operators
for the modification of important visual characteristics such as highlights,
roughness, and fuzziness. Results compare favorably to the direct alteration of
micro-geometry and reflectances of ground-truth synthetic data.
