<p class="MsoNormal"><span lang="PT-BR">Hello all!<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="PT-BR"><o:p> </o:p></span></p>
<p class="MsoNormal">I have succeeded in building VTK with vtkOpenVR remote module and running a simple Cone example in my OSVR HMD.
<o:p></o:p></p>
<p class="MsoNormal">But when I’ve attempted to run the volume rendering example "GPURenderDemo", I got a black screen and a lot of repetitive errors:<o:p></o:p></p>
<p class="MsoNormal"><i>ERROR: In<o:p></o:p></i></p>
<p class="MsoNormal"><i>C:\VTK-master\Rendering\OpenGL2\vtkTextureObject.cxx,<o:p></o:p></i></p>
<p class="MsoNormal"><i>line 2035<o:p></o:p></i></p>
<p class="MsoNormal"><i>vtkTextureObject (0000000BE6462060): failed at glCopyTexImage2D 6402 1 OpenGL errors detected<o:p></o:p></i></p>
<p class="MsoNormal"><i> 0 : (1282) Invalid operation<o:p></o:p></i></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also, I have tried to run the CPU-based volume rendering example “FixedPointVolumeRayCastMapperCT”.<o:p></o:p></p>
<p class="MsoNormal">Although the performance is poor, it works, since the texture successfully appears in the HMD and its tracking is integrated with the WindowInteractor.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My colleague has made an investigation about this issue comparing both examples, he concluded that the problem is related with the “SmartVolumeMapper” class.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So I would like to ask a few questions:<o:p></o:p></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><![if !supportLists]><span style="mso-list:Ignore">1)<span style="font:7.0pt "Times New Roman"">
</span></span><![endif]>Does the remote module vtkOpenVR has support for volume rendering?
<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:18.0pt">2a) If it does, what I'm doing wrong? Is there any problem with SmartVolumeMapper implementation for running vtkOpenVr applications?<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:18.0pt">2b) If it don’t, how I can add volume rendering support for vtkOpenVR? (I and my team are willing to do this)<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you very much!<o:p></o:p></p>
