Hey guys,<br>
<br>
here is a 2D example of what I wanted to do. I think data
transformation would not be the correct way of doing this.<br>

is it possible to change the tick of the axes? Right know using
the transform filter is equivalent to the second image.
Unfortunately that is not what I would like to have. I think the
best way to do this is to change to tick of the Z-Dimension.<br>
<br>
The image has the dimensions 520x520x47. So the tick for x and y
is 1, for z it should be 47/520. I don't want to change the data.<br>

and I would like to "stretch" the Z-axis to get more like
a cube visualization.<br>
<br>
I used vtkTransform to transform the axes, but I would
change the data if I do this. I hope you understand what I
want to do, e.g. is there a possibility to change /
stretch the ticks of a specific axis.<br>
<br>
The vtkTransform plot stretches to much:<br>

The data is deformed<br>
<br>
I use the vtkTransform like this:<br>
vtkSmartPointer<vtkTransform> axis =
vtkSmartPointer<vtkTransform>::New();<br>
axis->Scale(1,1,10);<br>
<br>
dataActor->SetUserTransform(axis);<br>
outlineActor->SetUserTransform(axis);<br>
<br>
I tried using the camera with the vtkTransform, but the
only thing I got from there, was an empty image or I had
to zoom out greatly.<br>
<br>
For matlab reference, something like this:<br>
<a moz-do-not-send="true"

Hey guys<br>
<br>
i'd like to ask you if there's a equivalent method
for vtkRenderWindow for equalizing the axis, just
like MATLABs axis equal. Could vtkAxesActor be
helpful?<br>
<br>
I hope you can help<br>
<br>
Thanks<br>
