A beginner needs help:
I want to map a texture on a sphere but encountered the following problems:
Please see http://www.cs.rpi.edu/~cana/Problems.htm
1) The ascept ratio is lost, although I am using the same scale factor for each dimension
xform->SetScale(1.3, 1.3, 1.3);
2) There is a leak in the texture.... Please see the above web site.
3) I couldn't find any documentation about what the units are for the command
xform->SetPosition(float, float, float);
What are the units of these floats; rad, degree, pixel?
More importantly, if you can direct me to web adresses that I can find such information that would be great.
I used the following classes.
sphere = vtkSphereSource::New();
tmapper = vtkTextureMapToSphere::New();
