I am considering options to copy or clone a terrain database to have
one on the top of the other. The purpose of this is to attach two
different textures to the two separate but geometrically equal terrains.
Its nice to be able to pfClone the whole group and/or dcs of the terrain
and move it a few meters up or down. Once I've cloned it can I change
the terrain texture of one without changing the texture on the other? Can I
get at the gset and gstate to do this?
How about the option of using pfCopy? I can copy the Geode and the
group but again how can I get the gstate to change the texture? Granted
that this is possible, if I change the texture of the copy will it change
the texture of the original?
Last one. I noticed that in the Performer 1.2 manual there is a brief
reference to the the pfCopyGSet (pg 243) which it says that it can "Make a
copy" of the GSet. However, online man pages does not have any
reference to it. I suspect that this was omitted from the library but
not the hardcopy manual pages. It sure would be nice to be able to copy
the geometry sets so as to be able to create a new geode with a new
gstate and thus a new texture. I tried to pfCopy the geometries but got
a core dump.
If anyone read this much, I would appreciate any suggestions very much.
