Every vowel has unique phoneme and unique viseme, therefore every vowel needs to have a specific representation. 5.1 Data import System uses VRML model representation. The data of model are described in a prototype based on the IndexedFaceSet node. This node contains all necessary information about polygonal mesh. The prototype contains a few arrays.
Next array determines control points of the model.
This array contains indices to the array of vertices. We used 130 vertices and 220 faces for description of our model. 5.2 Data structures We used mostly two-dimensional arrays for data representation. A real data are only in the arrays containing vertices and colours. A data in other arrays are indices to the another arrays.
