Question about creating faces

OpenGL OpenGL: Advanced Coding
1

Hello guys,

I’m with a big problem, and I’m trying to find the best solution for this problem, I will try to explain :

I have a model (that is digitized in slices / sections), now I would like to render it, it means that I have to make the faces and I also want to export it in some formats, but not in slices, in faces, the question is : How to create the faces (QUADS or triangles) based in my slices model ?

Any help will be apreciated

Thank you for the moment.

Happy 2002 for everybody.

Kurt

BTW : is there any brazilian guy here ?

hi,

conceptually, what is slices ? how do you get a display with slices ?

5

Slices are sections / curves , in fact what I have is a cloud of points, with this cloud of points I can create sections, based in this sections, I would like now to create the faces.

Lets imagine a rectangle :

------------- These
|----------| are
|----------| my sections / slices

----------

Hope I’m clear now.
Thank you
Best regards
Kurt

You could also generate surfaces directly from your point clouds for better results.

Here is a starting point:

I’m not sure if you can find what you want from http://www.kitware.com, to download VTK(The Visualization Toolkit) there.

Don’t forget to http://www.cmake.org/CMake/HTML/Download.html to download CMake to compile the source.(the VTK document talk about it, but it didn’t in the VTK package)

VTK is really a powerful tool.It includes a lot of methods to visualize various data sets(eg. scalar field¡¢vector field…).You will like it.
