Hi,

I'm trying to use fluxed pfGeoSets for some dynamic geometry. I want the
number of primitives to vary which is why AFAIK complete pfGeoSets can
be pfFlux'ed as opposed to just the attribute arrays.

My question is when I create a pfFlux'ed geoset with

pfFlux *fluxed_geo = pfNewFluxInitFunc(initFunc,
PFFLUX_DEFAULT_NUM_BUFFERS, arena);

how can I get any arguments to my initFunc?

The manual says the callback is of type:
typedef int (*pfFluxInitFuncType)(pfFluxMemory *_fmem);

Compare this to function pfFluxCallDataFunc() to manipulate the data
which *does* allow user data to be passed to the callback function. I
would expect something like this.

All the examples just create geosets with fixed numbers of vertices etc.
so they can't help.

Any suggestions?

Regards, Simon
