There is one file containing all the time samples so I need to be
able to at least query our API to see if the geometry has changed on
each frame.
Is this because the file is dynamically changing its contents without changing its file name?
Forcing it to re-read on a frame change is a pretty wasteful way to do it - include the modification time of the file in the hash instead:
struct stat st;
if (stat(filename(), &st)==0)
geo_hash[Group_Primitives].append(&st.st_mtime, sizeof(time_t));

> Is there a way to force ReadGeo to update reading frames for a single file (no single file per frame)? I wrote a custom GeoReader node that is working but not updating. I creating a derived class from ReadGeo overriding the append function as suggested in a previous post and also tried animating parameters in the ReadGeo node. Is there another way to force ReadGeo to execute the GeoReader geometry_engine call?
