<p>Hi Everyone,<br>
<br>
I have a problem understanding how to interpret the size of the rendered image.<br>
<br>
I render an actor with ParallelProjection. <br>
<font face="Courier New">camera->ParallelProjectionOn();</font><br>
I define the clipping planes using <br>
<font face="Courier New"> </font><font color="#0000FF" face="Courier New">this</font><font face="Courier New">->ren->ComputeVisiblePropBounds( allBounds ); </font><br>
<font face="Courier New"> </font><font color="#0000FF" face="Courier New">this</font><font face="Courier New">->ren->ResetCameraClippingRange( allBounds );</font><br>
and the scale by:<br>
<font face="Courier New"> camera->SetParallelScale(zoom);</font><br>
<br>
<br>
<font face="Courier New">How can I know the size of the rendered image in the viewport in real world coordinates, from these (or other) parameters?</font><br>
<br>
<font face="Courier New">Thanks,</font><br>
