Taking things into his own hands, so to speak, guil from the WorldWind forums has been working on an updated version of the Virtual Earth plug-in and has posted his results for testing. You can download the new plug-in from here.
Fixes/Updates:
- Corrected some bugs concerning column and row wrap-around (tiles from south pole appearing in north pole, tiles with negative row or column indexes)
- Removed the need for proj 4, by encoding directly the Mercator projection and simplified some code managing the projection. It should improve slightly the performances
- Also added a transparent border/road/name layer
- Main modifications concern the optimisation of the mesh creation algorithm. I worked in radian instead of degrees to reduce angle conversions. I also changed the way it reprojects. The overhead due to Mercator reprojection is now linear in Meshpointcount instead of quadratic previously. This could significantly improve performances when using large Meshpointcount
- Fixed bug that causes crashes when downloading large numbers of tiles
