<br>
I'm looking for an example that does this or a few examples that show the proper way to do this.<br>
<br>
I'm not sure how to understand vtkProbeFilter from <a href="http://www.vtk.org/doc/nightly/html/classvtkProbeFilter.html" target="_blank">http://www.vtk.org/doc/<u></u>nightly/html/<u></u>classvtkProbeFilter.html</a> and what part of it will do the work I need.<br>
<br>
vtkProbeFilter->Probe requires three vtkDataSet but how do I get my points into a dataset?<br>
<br>
Thanks for your help,<br>

Hi,<br>
<br>
I am interested in creating the following simple example in order to expand off of at a later time:<br>
- Create a cube (8 points) with scalar values all set to 1<br>
- Create a line (5 points) that intersects with cube<br>
- Get scalar interpolations for the line from the cube<br>
<br>
Cube pts:<br>
float pts[8][3] = { {-1.0, -1.0, -1.0}, {-1.0, 1.0, -1.0},<br>
{-1.0, 1.0, 1.0}, {-1.0, -1.0, 1.0},<br>
{1.0, -1.0, -1.0}, {1.0, 1.0, -1.0},<br>
{1.0, 1.0, 1.0}, {1.0, -1.0, 1.0} };<br>
Line pts:<br>
float line[5][3] = { {-2.0, 2.0, -2.0}, {-1.0, 1.0, -1.0},<br>
{0.0, 0.0, 0.0}, {1.0, -1.0, 1.0}, {2.0, -2.0, 2.0} };<br>
<br>
I could not find a simple example to do this, and I'm not exactly sure if probefilter is the right way to go about this. What the best (and easiest) way to approach this problem?<br>
<br>
Thanks,<br>
~Brian<br>
