Can ParaView render an isosurface = 1 from the UNSTRUCTURED_GRID attached? “Points Gaussian” represents it correctly (screen shot 1). But “Contour” filter fails.
Many thanks.
STEPS TO REPRODUCE ISSUE:
-
Download UG_sample.vtk (44.2 KB)
-
Open UG_sample.vtk in “Legacy VTK Reader”
-
Select:
Representation = Point Gaussian, Coloring = sphere_markers, Gaussian Radius = 0.04.
Result: All works as expected:
Correctly renders data points for 8 spheres (see screen shot).
Scalar values:0 = Blue = center of 8 spheres. 1 = Yellow = points on surface of such spheres. 2 = Red = points in the space between spheres.
UG_sample.vtk → Information:
Number of cells 24 Number of points 1192 Data range: sphere_marker float [0,2]
- Add filter: “Contour”.
Result:
Expected:
- Renders isosurfaces ( = 1, for 8 spheres).
- “Contour → Information” same as as “UG_sample.vtk > Information”.
Observed:
- Renders no surfaces.
- Contour “Information”:
Number of cells 0
Number of points 0
Data range: Not available
Output Messages:
- None.
- Optional additional attempts:
Repeat steps above for:
- UG_minimal-VTK_VERTEX_only.vtk (5.9 KB) ,
- UG_minimal-VTK_HEXAHEDRON_and_VTK_VERTEX.vtk (615 Bytes) , or
- UG_minimal-VTK_POLY_VERTEX_and_VTK_VERTEX.vtk (614 Bytes)
Result:
Same as above (issue persists).
