Summary | 0003951: VTK OpenGL2 Backend: GPU VR - Slower than CPU VR | ||||
Description | From Ron: the speed is not there yet at all. This is slower than CPU rendering on my machine Slicer binaries with OpenGL backend available here: http://download.slicer.org Tested on MacOSX using Slicer version based of VTK d733280 provided by installer from 2015-02-09: Slicer-4.4.0-2015-02-09-macosx-amd64.dmg - http://slicer.kitware.com/midas3/item/176422 Slicer-4.4.0-2015-02-09-win-amd64.exe - http://slicer.kitware.com/midas3/item/176423 | ||||

@Ron: Could you provide the FPS for the following cases: (1) Regular Slicer binary GPU VR FPS can be displayed clicking on the "..." in the 3D view controller panel. Could you also provide info about the GPU card installer on your workstation ? |

GPU card: NVIDIA GeForce GT 750M 2048 MB VTKOpenGL2 backend (based of VTK d733280):

|
I used one of the slicer sample data sets (chest, see under welcome module, sample data sets), one of the presets (chest-contrast-enhanced) and ROI clipping. I slightly modulated the preset using the shift transfer function in the VR module panel. This should be perfectly reproducible to the vkt team and allow them to measure any additional metrics that they need. I do not have access to the regular Slicer with the same SVN number and I already provided |
|
VTK rendering experts are looking at profiling OpenGL code to see where the GPU mapper can be improved. |
|
revisit this with OpenGL2 backend |
|
@kikinis Since the nightly build of Slicer now include the newer VTK OpenGL2 backend, is this still an issue ? |
|
Following last exchange with @kikinis , the GPU rendering is now behaving much better. |
