I am having an issue using vtkScalarBarActor in WebAssembly. The code works correctly in C++ desktop VTK, but I get the following error when running it in WebAssembly in a browser: WebGL: INVALID_ENUM: texParameter: invalid texture target Here is the code: vtkSmartPointer<vtkLookupTable> looku…

I solved my immediate issue by modifying the vtkScalarBarActor code by setting point scalars instead of cell scalars on the scalar bar polydata object. This works in this instance, but anytime you use a vtkPolyDataActor2D with cell scalars it will fail when using WebAssembly. Hope this helps someone…
