[Openal-devel] AL_EXT_source_distance_model revisit

[Bob Aron]

• What happens when some of the sources are set to something other  
than the default and then the application calls alDistanceModel()?

Do all the sources then switch to the new default? including those  
that had been explicitly set to some 'non-default' distance model  
already. If not, then the source object will have to maintain state  
not only for which distance model it should be using, but also whether  
it was explicitly set.

• What is the purpose of having different distance models for each  
source?
