I also look forward to checking out your updated site, I have recently discovered the joys of flash 4 and will be setting up my own site within the next 2 months (time permitting)

Also FYI, I am writing a modified Terrain Engine for work that should be able to load DTM files, and display using an adaptive realtime LOD algorithm. (A modified version of the ROAM algo) This should take quite a while, but no reason I cant post it to you when complete. (They want to be able to show detail down to 1m x 1m squares, encompassing data grids up to 1024x1024 & beyond)

If future hardware supports it, then PR will be able to use bump-mapping on it.

Good to hear that PR3 would be ready in form.
Have a nice Holiday!
