Highlight on hover and select on click

[DKGH]

Is there a way I can highlight an TopoDS shape object by hovering over it and then select it by clicking on it.

Looking for a functionality similar to what AIS interactive context provides.

Currently, you would have to implement that yourself, using a JS 3D engine like ThreeJS.

In the future, I want to make it possible to use OpenCascade's / OCCT's visualization and GUI API's, which could make a use case like you're describing much simpler. I have made some experiments and a demo for a STEP file viewer, where you can see that in action: https://occt-viewer.web.app/ However, the approach I used in that application is extremely hacky and has severe pitfalls. Doing this properly would make it necessary to handle multi-threading in an improved way, which is something I want to address in an upcoming version.
