Macro Definition Documentation

◆ MAX_GPU_SUBDIV_SSBOS

#define MAX_GPU_SUBDIV_SSBOS 12

Hard-coded for until GPU shaders are automatically generated, then we will have a more programmatic way of detecting this.

Function Documentation

◆ BKE_subsurf_modifier_can_do_gpu_subdiv()

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

Return true if GPU subdivision can be used for this modifier. It does not check if the modifier is in the right place in the modifier stack, only if the settings and GPU are compatible.

◆ 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.

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.
