Description:
souhrn:
Continuously increasing computational power of graphics hardware enables to use fast and realistic rendering of virtual reality models. These models require, among others, natural looking textures covering faces of rendered scene. The textures can be represented by texture models, which should approximate the textures with photorealistic material appearance. It is useful for complex tasks as visual safety simulations or interior design in automotive/airspace industry or architecture.
One of promising ways of capturing material's attributes is using more complex representations of rough or 3D textures called Bidirectional Texture Functions (BTF). The BTF are six dimensional functions depending on view and illumination positions as well as on planar texture coordinates.
In this lecture, the methods recently used for BTF acquisition, compression, and synthesis, will be discussed. Furthermore, mapping of arbitrary surfaces and two different BTF modelling pipelines will be introduced.
