GU_Detail* POP_Node::getGeo	(	const char *	overridegeopath,
		const POP_ContextData *	data,

		GU_Detail *	copygdp,
		OP_Node **	prevsop,
		int *	retdoxform,
		UT_DMatrix4 *	retxform,
		int *	retneedsreset
	)

This function provides a whole bunch of slightly different functionality to each of a bunch of different POPs (thus the complex signature). Any POP which accesses a piece of SOP geometry should use this function to get the geometry. It supports DOP geometry paths as well. The first parameter is the path to get the gometry from. If NULL, the data and t parameters are used to evaluate parameters on the POP to get the path. addextrainput tells it whether to add an extra input to the POP for when the SOP changes. ignorexform tells this function to ignore any transform on the object containing the SOP (or DOP). copygdp provides a place to stores a transformed version of the geometry if required. This and all subsequent parameter can be NULL if the information isn't required (such as when the geometry is being accessed just to get a list of available group names). The prevsop parameter can point to the SOP that was last retrieved. It's value is updated by this function, after doing a comparison to see if the value has changed. retdoxform and retxform return whether a transform is required on the geometry, and what that transform is. Finally, retneedsreset helps POPs keep track of whether anything has changed since the last call to this function. This takes into account changes to the prevsop, whether or not the geometry has to be xformed, and the value passed in through retneedsreset.

pseudocook() is used to traverse all nodes and perform some method one each node in the cook chain.

static void POP_Node::reapParticles ( OP_Context & context ) [static]

reapParticles() removes dead particles from the system.

virtual void POP_Node::timestep ( OP_Context & context ) [virtual]

timestep() is used to perform timestepping. (i.e. move particles, update state, etc). This function can be overridden to perform a custom integration step. The default implementation calls the static timestepStatic function. Note that this function is only called on the cook POP, not every POP in the network.

static void POP_Node::timestepStatic ( OP_Context & context ) [static]

Standard particle timestep function.

void POP_Node::traverse	(	POP_TraverseFunc	traverse,
		void *	userdata = `0`
	)

traverse() is used to traverse all nodes and perform some method one each node.

void POP_Node::traverseNode	(	POP_TraverseFunc	traverse,

GU_DetailHandle POP_Node::myGuideHandle [protected]

The guide handle owns the guide detail and permits indirect (external) references to the POP_Guide. Within the context of this node, we can safely use myGuide as a convenient way to avoid casting.

Warning:: Preserve requests are ignored.
