vtk.js controlling antialiasing


Is there any way to control anti aliasing quality in vtk.js? I couldn’t find any options like renWin->SetMultiSamples(x) that’s available in “normal” vtk.

At the moment I think the anti aliasing quality is somewhat automatic? I noticed that it’s much worse for elements with an opacity < 1, e.g. in the examples the CellPicker example has much smoother lines than the PointPicker example.

AFAIK, the only antialiasing vtk has is the browser’s automatic aliasing
A parameter of getContext on the canvas can ask for antialiasing
If the browser is able to perform AA and you didn’t explicitly disable it, it will be performed
