<DIV><FONT face=Arial size=2>Hello vtk users,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I am creating a scene with an object in the centre.
I'd like to</FONT></DIV>
<DIV><FONT face=Arial size=2>create another object located on the surface
of a sphere,</FONT></DIV>
<DIV><FONT face=Arial size=2>in orbit if you will, around my central object. I'd
like to know</FONT></DIV>
<DIV><FONT face=Arial size=2> the best way of going about it.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've looked at vtkSphereWidget, but I'd like to
create </FONT></DIV>
<DIV><FONT face=Arial size=2>something a little more simpler than this. I don't
need the</FONT></DIV>
<DIV><FONT face=Arial size=2>orbital object to be placed anywhere on the surface
of the</FONT></DIV>
<DIV><FONT face=Arial size=2>sphere. I only require it to be placed on each
Theta and Phi </FONT></DIV>
<DIV><FONT face=Arial size=2>step, i.e. where the latitude and longitude lines
cross on</FONT></DIV>
<DIV><FONT face=Arial size=2>a wireframe, LatLongTessellationOn() set
sphereSource.</FONT></DIV>
<DIV><FONT face=Arial size=2>Moreover, I'd like the entire scene to be enabled
with a </FONT></DIV>
<DIV><FONT face=Arial size=2>mouse interactive camera, so that also rules out
the </FONT></DIV>
<DIV><FONT face=Arial size=2>sphereWidget as the examples that I've seen doesn't
let</FONT></DIV>
<DIV><FONT face=Arial size=2>you move the camera when the widget is
active.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I've created a wireframe LatLongTessellationOn
sphere,</FONT></DIV>
<DIV><FONT face=Arial size=2>of which I have set the Theta and Phi resolutions.
I was </FONT></DIV>
<DIV><FONT face=Arial size=2>wondering if there is a simple and efficient way to
get the</FONT></DIV>
<DIV><FONT face=Arial size=2>points of where the wire lines cross in this
sphere. I'd like </FONT></DIV>
<DIV><FONT face=Arial size=2>to reference these points as well in respect to the
Theta </FONT></DIV>
<DIV><FONT face=Arial size=2>and Phi resolutions, i.e. with resolutions of 10
each, Phi's </FONT></DIV>
<DIV><FONT face=Arial size=2>first point is at the bottom and starts
at 1 and steps up to</FONT></DIV>
<DIV><FONT face=Arial size=2>the top at 10. And similar for Theta.
Please could someone</FONT></DIV>
<DIV><FONT face=Arial size=2>point me in the right direction.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If anyone has done something similar to this and
think that</FONT></DIV>
<DIV><FONT face=Arial size=2>my approach is more complicated than it needs to be
please</FONT></DIV>
<DIV><FONT face=Arial size=2>let me know. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Kind regards,</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
