| Virtual
textures for virtual models
The MURALE
project develops novel tools for the recording and reconstruction of archaeological
finds. Central issues are the flexibility and user-friendliness of these
tools. Therefore, the type of operation required must not be more complex
than taking photographs, and the devices should be portable so that they
can be brought onto the site. The project has developed such tools for
the acquisition of 3D models, and this for objects of different sizes.
These models can then be used to produce virtual sites, that people can
visit from remote locations. 3D shapes are only part of the information
needed to build the models. At least as important for the creation of
a veridical impression are the textures that are mapped onto the surfaces.
The contribution presents recent MURALE work on the synthesis of textures
of building materials and landscape vegetations, with as only input that
is required example images of these textures. Based on the latter, texture
models are extracted, that allow for the synthesis of as much of similar
texture as needed. An important advantage of the stochastic teture approach
is that no verbatim copying takes place, thereby avoiding artificial repetitions
in the texture. |
