I've written something similar, however my program evaluates a point cloud of random data triplets, and computes a best-fit smooth height field from the data. The density of the grid is user-defined, and the size is set automatically to the bounds of the data. The surface is color-mapped by elevation. A lot of what you'll need is in the program, but it's mixed in with all the other functions. If you'd like to take a look at it, just let me know. -----Original Message----- From: H.........

Hello, Iīve got a question with implementing following problem: A 2-dimensional rectangular Matrix should be transformed into a 3-dimensional visualization of the matrix. The values at each position should represent the height of the actual point. (The program should work like the 'matrixplot' in Maple. ) There are two desired appearances of the 3-dimensional visualization which I want to implement. But at first number 1 is more important: (1) the output of the visualization consists of triangulars. The corners of the triangular are the values of the matrix. (2) The sharph edges (of the triangular) should be transformed into a smooth curve. But I donīt know how to implement this. Perhaps splines are a solution!? Are they implemented in Java3D? How can I find information about it? Other Constraints: A coordinate-system should also be added, with the x-axe (rows of the matrix), y-axe (colums) and the z-axe (the value of the matrix). Light effects and interactive views (clicking with the mous or with the arrow-key should change the point of view) should also be part of the implementation. Every point and the near area around should be in a height-dependent color. Has anybody suggestions about implementing this problem? Which would be the best algorithm? Has anybody already written some code with a similar problem or knows where I can find code? Do you know some urls where I can find special information, hints, tips about the implementation? For all suggestions and answers thanks a lot! With best regards, B.
