<div>Dear VTK Users;</div><div><br></div><div>I have worked on a project that requires a Polygonal Object ( or at least a simple Line ) to be moved on the fly on a volume rendered scene built on top of a vtkVolumeRayCastMapper abstraction. </div>
<div><br></div><div>This goal was successfully reached but we have faced a drastic performance degradation when moving the polygonal object into/across the volume scene. We have assumed this is a consequence of the VTK's pipeline processing model. If anyone confirm that, we would like to ask any help in the sense of pointing any strategy for achieving any (minimal) performance improvement.</div>
<div><br></div><div>Perhaps, getting the OpenGL Context and rendering our polygonal object using OpenGL commands; thus skipping the VTK's pipeline processing. Is this feasible?</div><div><br></div><div>Thanks in advance for any help.</div>
<div><br></div><div>Regards,</div><div><br></div><div>Fauze</div>
