Hello all,
now I am doing volume rendering with vtkVolumeRayCastMapper and I'm wondering how to do to know the progress of the rendering.
I've seen that in vtkCommand.h there are some EvnetsId (VolumeMapperRenderProgressEvent, VolumeMapperComputeGradientsEndEvent, VolumeMapperComputeGradientsProgressEvent, VolumeMapperComputeGradientsStartEvent) that could be uses for this purpose.
How , I don't know !!!!
could someone help me to recover such information. The rendering of a high number of mediacl images takes a lot of times ( depending of the quality LOD, Shade..) and I want to put a progressbar to indicate the progression of the rendering to not make the user think that it's an endless loop.

thank you.
