[vtkusers] QVTKWidget and Depth Peeling Revisited

[Matt Sutton]

Folks,
   Sorry for the noise.  It looks like you actually have to have an actor that *is* transparent included in the renderer for depth peeling to be used, even if you've requested it to be activated.  Looks like I was bumping up against an somewhat obvious optimization.  Once I included an actor that was not fully opaque the rendering code reported that depth peeling was activated.
Regards,

Miro,
  Yes, I have seen that example.  It is what I've used as a reference implementation.  The only thing different, that I can tell, with my implementation and this is that I am using the QVTKWidget inside a Qt application.   I found this post:

Which is virtually identical to my situation, but I don't see a resolution anywhere.  Thanks for the suggestion, though!
Matt

Matt,

have you seen this example?

Subject: [vtkusers] QVTKWidget and Depth Peeling Revisited


Hello,

   I'm trying to use depth peeling within a QVTKWidget based application.  Currently, my renderer always returns 0 for GetLastRenderingUsedDepthPeeling().  I'm using VTK 6.3 with a NVIDIA K6000 GPU and the latest NVIDIA driver.  I've configured VTK to use the OpenGL2 rendering backend during the CMAKE configure step.  I've searched online and found a few messages from 2013 regarding a similar issue, but I can't seem to find the solution?  Any help or insight would be appreciated.

Regards,

Matt
