volume rendering in IDLgrVolume [message #32132]

Hi all,

I have some questions about the volume rendering algorithm used for
IDLgrVolume:
- Is it true that the volume rendering algorithm used for IDLgrVolume is
encapsulated in this class?
- Where can I find more information than in the idl reference manual on
the algorithm used? What I am especially interested in is:
-- How are multiple volume rendered (just stand-alone and than blended
together or something more sophisticated)?
-- Can I manipulate single viewing rays? Like setting different
start/termination depths and getting a map of all termination
depths?
- Can I somehow tell the IDLgrVolume to use another rendering algorithm?
Would it be enough to derive a subclass from IDLgrVolume and override
some function (if, which function, draw would be much work?)
- Is the code for IDLgrVolume and its renderer available (might save a lot
of work to simply change it somewhat)

Thanks a lot in advance & best regards from sunny spain,

Sebastian
