Angel, I think the labels look pretty good.
There must be some way of defining the VRML view -- look for a
definition of a 4x4 transformation matrix (includes zoom and
centering) or a 3x3 rotation matrix. Those are available via Viewer
methods. We sidestepped this in POV-Ray by using the screen xyz
coordinates, which already take into account perspective. But the
method is there:
public Matrix4f getMatrixtransform() {
return transformManager.getMatrixtransform();
}
Then you can do what you want with that. Alternatively, if you need
something else, you could get the axis and angle and do something with
that.
void getAxisAngle(AxisAngle4f axisAngle) {
transformManager.getAxisAngle(axisAngle);
}
The distortion is due to the perspective having the camera too close
to the model. I think you just have to get close, not a perfect
rendition the way we have done in POV-Ray -- there the idea was to get
a perfect rendition of the specific view. Here we are after a more
adaptable representation.
