<div dir="ltr">Hi Chao,<div><br></div><div>As far I now, vtkGPUVolumeRayCastMapper try to see if your system meet the requirements ( a compatible graphics card with proper drivers, for example ) and will do the best to start the volume rendering. If you not sure about your system, try starting using <span style="font-weight:bold;color:rgb(84,84,84);font-family:arial,sans-serif;line-height:20.22222328186035px">vtkSmartVolumeMapper</span><span style="color:rgb(84,84,84);font-family:arial,sans-serif;line-height:20.22222328186035px"> </span>instead, since this mapper will do the choices for you, and instantiate a proper mapper ( only will instantiate vtkGPUVolumeRayCastMapper if your system are compatible ).</div>
<div><br></div><div>If you really wants to instantiate vtkGPUVolumeRayCastMapper directly, please provide more information about your system ( operating system version, graphic card, etc ) and if possible provide your code too.</div>
<div><br></div><div>In next mails, please copy the list. You have more people to answer your questions and the answers will be available to future searches.</div><div><br></div><div>Regards,</div><div><br></div><div>Wagner </div>
