POP extra inputs

[Guest xionmark]

Hello,

This has got to be an easy one. I need to read the particles coming into the 2nd and 3rd inputs of a POP but I've come up empty. There doesn't seem to be a method to read the data from a specified input like in SOPs.

POP_ContextData offers:
void 	getInputGeo (UT_String &path, int index) const
void 	setInputGeo (const UT_String &path, int index)

But that's for the SOP geo coming into the POP Network OP.

POP_Node has:
GU_Detail * getGeo (const char *overridegeopath, const POP_ContextData *data, float t, int addextrainput, int ignorexform, GU_Detail *copygdp, OP_Node **prevsop, int *retdoxform, UT_DMatrix4 *retxform, int *retneedsreset)

Which I use successfully to read geo from anywhere in SOPs, but it doesn't seem to have a form to read the particles from another POP node connected to a specified input to a POP. I've tried supplying the input path to getGeo() but Houdini complains.

So before calling POP_ContextData::getDetail(), how does one set the input for the data to be sourced from?

There's no inputGeo(), duplicateSource(), duplicateChangedSource(), useInputSource(), etc. in a POP_Node class. Surely there's a way to import particles as a separate GU_Detail than the "main gdp" in the POP_ContextData ? Is it right under my nose and it's too obvious? :-)
