I've been breaking my head on the very realistic looking pictures and animations which are in the free trial simulator here :
http://universesandbox.com/
Especially in one of the files one can see Earth rotating from space without flickering , and even the dark and light sides go smooth into each other . It's also possible to hoover over the poles and look from every direction without loss of realism over even the slightest flicker .
I know the program is writen in Visualbasic and I was wondering PowerBasic can also do such marvelous animations .
Anybody has any idea how this might have been done ?
Reason I ask this is that I've writen a gravity simulator myself ( in PowerBasic) wich also displays rendering of planet surfaces. But contrary to the example above the surfaces are still now static by lack of know how.
