Research Results

We have achieved a combination of image-based texture mapping and projective space (pseudo-solid) texture. This image-based texture mapping is useful for objects defined from volume datasets. We have also presented an approach to texture mapping volume datasets based on multiple semantic constraints. The approach is based on continuous space mappings to ensure good image quality. It requires only one intervention by the user, to determine key points where the texture must match an intermediate image of the original data. This can also be used to avoid the problem of texture being smeared over too large an area.

Dr Peiyi Shen prepared his second PhD thesis, arising from this work. It was successfully examined in 2007.
