We are working with Range Images and would like to visualize them using
OpenInventor 2.1, on a Indigo2, 128MB, R4400, Irix 5.3.
We have 3D points information and we want to make a landscape rendering.
Finally, we will have about 640x480 points.
We tested the SoTriangleStripSet and obtained the following results:
15 sec for calculation and visualization.
Only half of the surface had a hights variation. The rougher the surface
is, the slower gets the function (normal).
18 sec for calculation and visualization.
The more Triangle to calculate (rougher) the slower it gets, sometimes
the machine finishs the calculation and terminate the program with a
core dump without visualizing.
Next we did was introducing algorithms to cut down the number of
triangles which didn't show big differences.
Has someone already tried similar things and coulnd give us some ideas
about landscape rendering and visualisation of big data sets using
Thanks in advance.
