void DD::Image::ParticleOp::appendSimulationCurve

(

DD::Image::Hash &

hash

)

const

get the curve-hash that affects the particle system's simulation

void DD::Image::ParticleOp::appendSimulationInput	(	int	nodeInput,
		DD::Image::Hash &	hash
	)			const [protected, virtual]

get the curve-hash for the particle nodeInput. Subclasses can override this to not do anything or to only hash in particular data if the general curve-hash would not affect the simulation state.

void DD::Image::ParticleOp::add_input_handle	(	int	i,
		ViewerContext *	ctx
	)			[virtual]

we should ignore geo inputs for this purpose, as we shouldn't draw them if their panels are not open, and we don't want to suppress drawing them having lowered the state to CONNECTED from SHOW_OBJECT (see GeoOp::build_handles)

Reimplemented from DD::Image::Op.
