I am developing a C++ and OCCT based simple application on Mac OS Big Sur and trying to get visualization of the created STEP models (TopoDS_Shape) using VTK Integration Services (VIS) of OCCT. I installed OCCT on Mac using homebrew and I have the latest release of OCCT, 7.5.0.
The problem I am facing is that I am unable to find any of the "TKIVTK" libraries on my machine. I couldn't find any IVtkOCC_ShapeMesher classes as well. On top of that, when I search for the "IVtkOCC_ShapeMesher" class reference, just for an example, in the OCCT reference manual, its not mentioned in the 7.5.0 manual but only in 7.0.0 release's manual. Is VIS discontinued in 7.5.0? Do I need to manually build and install the OCCT with some custom options for VIS to work? Please suggest.
Thanks

OCCT formula in homebrew doesn't enable VIS component (there is no USE_VTK=ON option passed to CMake). So either you need building OCCT on your own or modify homebrew formula.
I hope that TKIVtk is perfectly buildable on macOS as it doesn't involve platform-specific code, but TKIVtkDraw (Draw Harness plugin for testing TKIVtk) is actually known to be not yet ported to macOS - see related bug #29187. This shouldn't be something blocking to use TKIVtk on macOS, though.
