PointPlacemark AlwaysOnTop

[SamCarter]

I noticed that PointPlacemark doesn't have an "AlwaysOnTop" attribute like some other renderables.

Currently, I am having ordering problems when using PointPlacemarks and Path renderables. I have a pointplacemark with an altitudemode set to ClampToGround and a path renderable with an altitudemode set to ClampToGround.

I would like the pointplacemarks to always appear on top of the paths, but have not found a way to do so. I noticed that switching to UserFacingIcon instead of PointPlacemark might work (since it has an AlwaysOnTop option), but didn't want to switch until absolutely necessary.

Anyone know of a way to accomplish this?

I tried changing the altitude mode of the pointplacemark to see if i could trick the ordering. I changed it to relativetoground and then gave it an altitude of 100, that way the point placemark is physically above the line.

It seems to work zoomed in, but as I zoom out, the path renderable again takes over and appears on top.

I switched from using Path to Polyline.

The same problem exists with the ordering. The Polyline appears on top of the pointplacemark, even if it is drawn on a separate layer that is below the layer containing the placemark.

Another update.

I have noticed that lines (Path or Polyline) also affect GlobeAnnotations, even though they are set to AlwaysOnTop. Zoomed in (closer than 10km) lines bleed through the annotations and appear above them.

I am beginning to think that I need to somehow alter the render methods of the Path/Polyline so that they don't always appear on top, or something along those lines. These are with Paths with an altitudemode of ClampToGround and Polylines with followterrain set to true.

However, if I tilt the globe, so that the pitch is not 0, the annotations once again take priority and appear on top.

I Tried setting getDistanceFromEye to 0 on the pointplacemark so that it gets drawn on top in the orderedrenderable queue. Paths and Polylines still get drawn on top.

Starting to run out of ideas.

This problem was around awhile ago:

I am not sure if it was ever solved

[SamCarter]

I managed to get it working somewhat.

Instead of clamping the Path to the ground, I set it to be 1 meter above the ground, which for my intents and purposes accomplishes the same thing.

After this is set, the point placemarks now appear above the path...that is until you zoom in really really close (below 1km) , but that is acceptable because the path is floating in the air as opposed to clamped to the ground.

To make the point placemark physically above the line, I set its altitude to 100 and converted it to relativetoground. tree service
