ImageActor should be opaque for the HardwareSelector to work #598

Closed cvandijck closed 3 years ago

cvandijck commented 5 years ago

The PropPicker (HardwareSelector) does not work for the automatically generate noise image. Adding imageActor->ForceOpaqueOn() solves the issue.

@cvandijck There have been changes to the original code for this example, so please check it out again.

It would be better to do this:

  if (argc != 2)
  {
    // Image should be opaque for the HardwareSelector to work
    imageActor->ForceOpaqueOn();
  }

Since the picking already works Ok if the image ColorCells.tif is used.
