Hi All,

I need to implement a dynamic 'drawing' overlay that is rendered onto a
model created using vpb. Has anyone tackled this so far?

My first thought is to use the osgSim Overlay as I have used this to do
the same thing on a flat world. Should this work for a geocentric model?


My first attempts at using it failed, but I am now pretty sure this was
due to the MultitextureControl turning off my texture unit, so I will
try again. Any thoughts on whether the osgSim Overlay is the best
approach / if it will work?

I will also need to select objects on this layer. My plan is to
intersect with the 3D model, get the lat lons, then convert this into
the reference frame used to render the overlay, and do a second
intersect operation from there. I think this will be fine but seems a
little complex. Does anyone have a suggestion for a better approach?

Cheers,

Brad

Hi Brad,

osgSim::OverlayNode does work for whole earth databases. Have a look
at the osgsimulation example for an example of this in action.
