Hi, I want to use OSG to create an overlay where I have different symbols marking certain points in my scene. I want these symbols to remain a constant size in screen coordinates until crossing certain thresholds (for example, they are size A when at a distance < X from the camera, then change to size B once distance > X). It’s a little different than a HUD because I want the symbols to move as I pan the camera, so that they stay at the same world coordinates. I am using an orthographic projection where the camera is directly overhead in the Z direction, and it will only pan in the X-Y plane.
I took a look at the OverlayNode class, but the description didn’t sound like what I wanted. The LOD class sounded more like what I need, so I could switch between multiple sized children based on the camera distance, but I’m still not quite sure how to make each child have a constant size within its camera distance range. Does anyone have any suggestions for me? Thank you!
