Function Documentation

◆ DEG_disable_visibility_optimization()

void DEG_disable_visibility_optimization ( Depsgraph * depsgraph )

Disable the visibility optimization making it so IDs which affect hidden objects or disabled modifiers are still evaluated.

For example, this ensures that an object which is needed by a modifier is ignoring checks about whether the object is hidden or the modifier is disabled.

◆ DEG_graph_new()

Depsgraph * DEG_graph_new	(	Main *	bmain,

		eEvaluationMode	mode )

Create new Depsgraph instance.

TODO: what arguments are needed here? What's the building-graph entry point?

◆ DEG_graph_replace_owners()

void DEG_graph_replace_owners	(	Depsgraph *	depsgraph,
		Main *	bmain,
		Scene *	scene,
		ViewLayer *	view_layer )

Replace the "owner" pointers (currently Main/Scene/ViewLayer) of this depsgraph. Used for:

Undo steps when we do want to re-use the old depsgraph data as much as possible.
Rendering where we want to re-use objects between different view layers.
