Hi!
I´d like to set a vtkDoubleArray with 3 Components, it should be a vector
array, the code looks like this:
vtkDoubleArray* momentum = vtkDoubleArray::New();
momentum - SetNumberOfTuples(numOfTuples);
momentum - SetNumberOfComponents(3);
for(vtkIdType i = 0; i numOfTuples; i++)
try calling SetNumberOfComponents first, the memory is allocated in the
call to SetNumberOfTuples

Also, if you SetNumberOfComponents, and SetNumberOfTuples, you want to
use SetTuple(i,Tuple) not InsertNextTuple, because that will add them at
the end.

What kind of dataset is this and which variable are you contouring by?
Before you can contour a dataset, you have to create cells (triangles,
quads, tetrahedras etc.) so that VTK has a way of interpolating values
over the area/volume. You can do this by using one of the Delaunay
filters but the
Berk,
I am trying to construct a 24 (hour) by 365 (days) plot of energy
values generated from a simulation and stored in SQLite.
The query that constructs a data table with the the three columns for
plotting is:
select [hour],(([Month]-1)*31+ [day]) as y, variablevalue
from reportmeterdata rmd
Mike,
This is a known problem with ParaView 3.4.0. The next version of ParaView
should have much more robust volume rendering.
Volume rendering is (mostly) clean in the trunk. You can build a version of
your own (see the ParaView web site wiki -
http://www.paraview.org/Wiki/ParaView, then
Make a new source code pull. This was broken the middle of last week, but was
fixed by Thursday or Friday. If you still have troubles after a new source
pull and clean cmake and build, let us know.
