[vtkusers] curved surfaces.

[Antonio Matta]

Hello,

Can anybody please tell me how can I create a curved surface using vtk?
So far I have tried with:

        vtkQuad
        vtkQuadraticEdge
        vtkQuadraticHexahedron
        vtkQuadraticPyramid
        vtkQuadraticQuad
        vtkQuadraticTetra

and I can not get a rounded vertice.

Many thanks for your help.

Antonio.

Subject: a little problem with threads.
 
Hi,

I am using a thread to control a rendering loop that simulates the motion of an articulated
system. Everything is implemented in Python.

#starting the thread for solid rendering
thread.start_new_thread(self.rendering_loop,(ren,VTKwindow,))

def rendering_loop(self,ren,VTKwindow):		
 #simulation loop
   for i in range( (self.pt-30)/30 ):
      self.genericHMTcompute( self.X[0, i*30], self.X[1,i*30] )
      self.Link1assembly.SetUserTransform( self.Link1.Trans )
      self.Link2assembly.SetUserTransform( self.Link2.Trans )
      VTKwindow.Render()

This is done in order to rotate or translate the camera or to select a button
from my graphical user interface while the simulutation is still active.

My problem is that if I rotate or translate the camera the simulation works fine, but
if I do not choose an event the simulation stops.

Can anybode tell what is going wrong?

Thanks,

Antonio Matta.
