Hide the icon of a PlaceNode

[marcoma9023]

As per the title,

after having created a custom widget similar to the PlaceNode, I would like to understand during the decluttering phase, i.e. when I have two overlapping PlaceNodes, how I can hide the icon behind it.

Currently the icon behind it is minimized, while the text is hidden.

I would like to have the same behavior for the icon too.

Ideas?

If you run the example osgearth_tracks you will see some options for controlling the decluttering behavior. These options are contained in the structure ScreenSpaceLayoutOptions and you can apply them by calling ScreenSpaceLayout::setOptions.

(Please note that in the master branch, you will need to enable the CMake flag OSGEARTH_BUILD_LEGACY_CONTROLS_API for the osgearth_tracks example to build. We have not (yet) ported the demo to use ImGui.)

Yes Glen, exactly what I was looking for.

osgEarth::Annotation::ScreenSpaceLayout::activate(_geodeStateSet.get());
osgEarth::ScreenSpaceLayout::setDeclutteringEnabled(true);
osgEarth::ScreenSpaceLayoutOptions options;
options.minAnimationAlpha() = 0.0;
options.minAnimationScale() = 0.0;
osgEarth::ScreenSpaceLayout::setOptions(options);

Thanks for the valuable reply.
