[vtkusers] animation of scalar values

[Peter Wallin]

Hi there!


I have an application where I animate deformation on a mesh by changing the scalefactor in vtkWarpVector filter for the vectors. Now I also want to include  stresses(scalar values) into the animation that also are to be animated. The scalars are mapped with the vtkBandContourFilter.

basiclly what I want to do for each timestep is to go through all the scalar vaules and multiply them with a current scalefactor. The scalarvalues that I read in are for the maximum stresses so by multipling them with a different scalefactor for each timestep I get a linear animation. Where the scalfactor range between 0-1.

some pseudocode:

GetPointData()

for (all the timesteps) {
		updatedScaleFactor=factor*i;
       for( all the points i ){
    i=i*updatedScaleFactor; }

Update Render;
}

Is there a method doing this that is  accessible for my scalarvalues or do I have to implement it myself. My main concern in that case is how to modify the point data.How to get it.

Any help would be grateful!
