Member Function Documentation

get_synthetic_group()

EggGroupNode * FltToEggLevelState::get_synthetic_group	(	const std::string &	name,
		const FltBead *	transform_bead,
		FltGeometry::BillboardType	type = FltGeometry::BT_none
	)

Sometimes it is necessary to synthesize a group within a particular EggGroup, for instance to insert a transform or billboard flag.

This function will synthesize a group as needed, or return an existing group (if the group need not be synthesized, or if a matching group was previously synthesized).

This collects together polygons that share the same billboard axis and/or transform space into the same group, rather than wastefully creating a group per polygon.

set_transform()

void FltToEggLevelState::set_transform	(	const FltBead *	flt_bead,
		EggGroup *	egg_group
	)

Sets up the group to reflect the transform indicated by the given record, if any.
