[osg-users] Shadows in large Urban area

2010-12-28 Thread Linda Lee 
Dear all,

I am new to OSG and is thinking of implementing shadows in a large urban area 
with lots of buildings.  Could anyone tell me if this is feasible and what 
shadow tecnique should I used?  Or should I try to implement a customized 
shadow algorithm?  Would computation performance be an issue?

Any suggestions and advices would be most welcome.  

Thank you!

Cheers,
Linda

Hi Linda,

For such cases we have 2 reasonable shadow tecs:
- Light Space Shadow Maps
- Parallel Splited Shadow Maps

did you tried out this both with osgShadow.exe -pssm  or with
osgShadow -lispsm ...
