I'm an MSEE student at the University of Texas at Arlington. I'm working on generating a hierarchically structured data base representation for terrain modeling. I'm working with: Matlab Wavelet Toolbox Digital Terrain Elevation Data
Our process involves using wavelets to generate a coarse approximation of the elevation posts and triangulate the posts to generate the root of the model (relatively few triangles, rough approximation). Then we use wavelet generated approximations to determine which triangles in the root need to be further refined. Our current triangulation scheme involves refining a triangle by connecting the midpoints of each edge (some added processing is done to ensure no wholes are generated in the model). We looking to implement a better triangulation approach. The output generated for a given model would be a file of points and a file of triangles (referencing into the points).
I'm interested in methods to display the triangulation results. I have seen a 2-D method in Nakamura's book on Numerical Analysis in Matlab. Does anyone have a 3-D method?
I'm also interested in any matlab triangulation method, like maybe Delaunay??
Also, is anyone working with elevation data and the Wavelet Toolbox or terrain modeling and Matlab?
