Hey guys, i took a test about variable instancing efficiency between vtk8.2 and vtk9.0 on different class.
Here was what i got:
testing times: 10000
Statistical method: average instancing time
the method instancing: vtkSmartPointer《class》 variable = vtkSmartPointer《class》::New();
VTK 9.0.3:
vtkGenericCell: 1.5002 us
vtkSphere: 0.0703 us
vtkSTLReader: 4.3552 us
====================================
VTK 8.2:
vtkGenericCell: 8.6075 us
vtkSphere: 0.2852 us
vtkSTLReader: 34.239 us
There are two questions for me.
FIRST, on the different version vtk, the same classes have significant instancing time that approximately is 10 times, and is there any optimizations?
SECOND, on the same version vtk, the different classes also have significant instancing time. what causes the difference?
Thanks for your reading!
