On item 2, currently there is no support for splines in Java 3D. This may
happen in version 1.4 but sun has not committed to it at this time.

Subject: [JAVA3D] 2-dimensional matrix -> 3D-visualization, splines,
coordinates, light-effects, interactive views,...
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. Hofmann
