<DIV>hi everybody,</DIV>
<DIV> </DIV>
<DIV>i am new to vtk and i am trying to build a 2D unstructured grid that represents a beam made of 8 triangles and 10 points.</DIV>
<DIV>i have already built a 3D unstructured grid using hexahedrons and things worked quite fine. On the other hands i always get an errror saying " nameofmyfile.exe has encountered a problem and needs to close". i am almost sure that nothing is wrong with the code which goes as follows:</DIV>
<DIV>// points coordinates</DIV>
<DIV> static float coord[10][3]=<BR> { <BR> {0,0,0},<BR> {1,0,0},<BR> {2,0,0},<BR> {3,0,0},<BR> {4,0,0},<BR> {0,1,0},<BR> {1,1,0},<BR> {2,1,0},<BR> {3,1,0},<BR> {4,1,0}};</DIV>
<DIV> </DIV>
<DIV>// Cells connectivity<BR>vtkIdType indices[8][3]=<BR> {<BR> {1,2,7},<BR> {1,7,6},<BR> {2,3,8},<BR> {2,8,7},<BR> {3,4,9},<BR> {3,9,8},<BR> {4,5,10},<BR> {4,10,9}};<BR> </DIV>
<DIV> </DIV>
<DIV> vtkPoints *pts=vtkPoints::New();<BR>for (int i=0;i<10;i++) </DIV>
<DIV> pts->InsertPoint(i,coord[i]);<BR> </DIV>
<DIV>vtkUnstructuredGrid *grid=vtkUnstructuredGrid::New();<BR><BR>for ( i=0;i<8;i++) grid->InsertNextCell(VTK_TRIANGLE,10,indices[i]);</DIV>
<DIV>grid->SetPoints(pts);</DIV>
<DIV> </DIV>
<DIV>vtkDataSetMapper *gridmap =vtkDataSetMapper::New();<BR>gridmap->SetInput(grid);</DIV>
<DIV> </DIV>
<DIV>vtkActor *gridact=vtkActor::New();<BR>gridact->SetMapper(gridmap);</DIV>
<DIV> </DIV>
<DIV>vtkRenderer *ren1=vtkRenderer::New();<BR>ren1->AddActor(gridact);<BR></DIV>
<DIV>vtkRenderWindow *renwin=vtkRenderWindow::New();<BR>renwin->AddRenderer(ren1);<BR></DIV>
<DIV>vtkRenderWindowInteractor *renwinint=vtkRenderWindowInteractor::New();</DIV>
<DIV>renwinint->SetRenderWindow(renwin);<BR></DIV>
<DIV>renwin->Render();<BR>renwinint->Start();</DIV>
<DIV> </DIV>
<DIV>the same code worked for the hexahedron. it's kind of strange that is not working for the triangles.</DIV>
<DIV>please help.</DIV>
<DIV>thx.</DIV>

The imagedata has point data only. This works relatively<BR>well, except at the edges of my domain. I sometimes get some values<BR>that are arbitrarily set to zero there. I have
attached an image<BR>(isosurfaceproblem.png) that shows that problem -- I know for a fact<BR>that the values at the bottom edge should NOT be zero (and should be<BR>smoother than what is shown). The result is very inconsistent -- i.e.<BR>if I change the input isosurface slightly, the location of problem<BR>points on the bottom edge will change. I also sometimes see this<BR>problem appear on other edges.<BR><BR>I have also included an image (slicenoproblem.png) that shows the same<BR>edge, but colored on a vtkImageGeometryDataFilter (i.e. just a<BR>'slice') of the domain. The lookup table for the value displayed is<BR>the same for both. This shows that there is no problem for the bottom<BR>edge...<BR><BR>Anyone have any idea what is going on? Is it possible that<BR>vtkProbeFilter sometimes 'misses' the source data and therefore<BR>outputs 0 at a location? Is there possibly a problem with my input (or<BR>source) data? I am using VTK4.4 on a Windows machine. Source code<BR>built using
VS.Net 2003.<BR><BR>Thank you in advance for all ideas/suggestions...<BR><BR>Charles Boivin<BR>-------------- next part --------------<BR>A non-text attachment was scrubbed...<BR>Name: isosurfaceproblem.png<BR>Type: image/png<BR>Size: 36960 bytes<BR>Desc: not available<BR>Url : http://public.kitware.com/pipermail/vtkusers/attachments/20050720/a27956a1/isosurfaceproblem.png<BR>-------------- next part --------------<BR>A non-text attachment was scrubbed...<BR>Name: slicenoproblem.png<BR>Type: image/png<BR>Size: 22639 bytes<BR>Desc: not available<BR>Url : http://public.kitware.com/pipermail/vtkusers/attachments/20050720/a27956a1/slicenoproblem.png<BR><BR>------------------------------<BR><BR>_______________________________________________<BR>vtkusers mailing list<BR>vtkusers@vtk.org<BR>http://www.vtk.org/mailman/listinfo/vtkusers<BR><BR><BR>End of vtkusers Digest, Vol 15, Issue 53<BR>****************************************<BR></BLOCKQUOTE><p>
