Function Documentation

BKE_subsurf_modifier_can_do_gpu_subdiv()

bool BKE_subsurf_modifier_can_do_gpu_subdiv	(	const Scene *	scene,
		const Object *	ob,
		const Mesh *	mesh,
		const SubsurfModifierData *	smd,
		int	required_mode )

Parameters

skip_check_is_last

When true, we assume that the modifier passed is the last enabled modifier in the stack.

BKE_subsurf_modifier_eval_required_mode()

int BKE_subsurf_modifier_eval_required_mode	(	bool	is_final_render,
		bool	is_edit_mode )

Return the ModifierMode required for the evaluation of the subsurf modifier, which should be used to check if the modifier is enabled.

BKE_subsurf_modifier_force_disable_gpu_evaluation_for_mesh()

bool BKE_subsurf_modifier_force_disable_gpu_evaluation_for_mesh	(	const SubsurfModifierData *	smd,
		const Mesh *	mesh )

Return true if GPU subdivision evaluation is disabled by force due to incompatible mesh or modifier settings. This will only return true if GPU subdivision is enabled in the preferences and supported by the GPU. It is mainly useful for showing UI messages.
