VTK hardware picker is slower than software picker
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Hi,
I compared software vs hardware method for selection : vtkRenderedAreaPicker (hardware) vs vtkAreaPicker (software) vtkPropPicker (hardware) vs vtkPicker (software)
I did tests on CPU i5-3450 CPU @ 3.10GHz :
- with integrated GPU
- with Nvidia Titan GPU
- with AMD Firepro W9000
My tests reveal that selection on models with 3e5 cells is way faster (>x5 speedup) using software than hardware methods. What's wrong there? On bigger models (3e6 cells), the selection speed is equivalent using the high end cards.
