Martin Schweiger's Orbiter simulator: Archives -- December 2002
Re: space elevator
i completely agree with you, but he hasnt replied my last email i sent him
regarding this matter, so ill send him another and wait a few weeks before i
make any decisions, thanks for your feedback!
what about point number 5? u didnt comment on that, the idea of using mesh
objects to act as chunks of 3d landscapes for individual sections of the
planet sphere. Surely colision detection could be done for those objects?
given that their smaller than the planet themselves.
Regarding the space elevator, im not sure where youre coming from with your
pesimism, are you saying it's not practical to SIMULATE it in orbiter? or
are you saying it's not practical do implement it in real life?
There has been extensive research done on the space elevator, and all the
experts to my knowlege has agreed it's possible and withing man's reach.
Only thing in dispute is the time frame to build it.
here are a few links to help convince you :
