[vtkusers] Fwd: VTK is completely Slow

[Thiago Macedo]

Hi,

I'm developing a CAD based software. At some point, the
app converts the 2D drawing into a 3D huge scene.
The main problem is: It's very slow!
I'm not using any complex algorithm neither complex structure. The
'translation' between 2D and 3D is very fast, and creates basic
geometries. E.g..:
A hydraulic tube is converted into a cylinder (vtkCylinderSource), the
connection between 2 hydraulic tubes is a sphere (vtkSphereSource);
A 2D line is converted into a 3D line (vtkLine)
All of 3D entities has a mapper and an actor.
I'm working with a lot of (closer than million) 2D entities, and the
3D scene is totally slow.
I've tried to use all tips wrote in the wiki (
http://www.vtk.org/Wiki/VTK/FAQ - How to handle large data sets in VTK
) and I have just a little improvement.
I searched into the books (v5) and was not able to find anything to
help me. I think it should be faster if I use simple structures like
cylinders and lines like I'm doing.
Is there a way to make it faster?

Thank you in Advance
Best Regards
