| Summary: | 碩士 === 國立交通大學 === 資訊科學學系 === 83 === We consider the problem of visualization of a set of 3D points
in this thesis. We classify the problem into two cases. The
first case is when the point set is dense and the other case is
the point set is sparse. In the visualization of dense point
set, we present a Grid Point Rendering Method. This method
would produce aliasing. We propose a Z-interpolation method to
eliminate such aliaing. The Grid Point Rendering Method can be
applied to render terrain data, which can be implemented by a
Sweeping Algorithm. We also present algorithm to map texture
maps onto terrain data. Finally, two methods to render the
sparse point set are discussed.
