Member Function Documentation

◆ attributes()

std::optional< AttributeAccessor > blender::bke::MeshComponent::attributes ( ) const

finalvirtual

Get access to the attributes in this geometry component. May return none if the geometry does not support the attribute system.

Reimplemented from blender::bke::GeometryComponent.

Referenced by attributes_for_write().

◆ clear()

void blender::bke::MeshComponent::clear ( )

overridevirtual

Remove referenced data from the geometry component.

Implements blender::bke::GeometryComponent.

Definition at line 42 of file geometry_component_mesh.cc.

References BKE_id_free(), BLI_assert, blender::ImplicitSharingInfo::is_expired(), blender::ImplicitSharingInfo::is_mutable(), and blender::bke::Owned.

Referenced by replace(), and ~MeshComponent().

◆ copy()

GeometryComponentPtr blender::bke::MeshComponent::copy ( ) const

overridevirtual

Copies the component. The returned component only has a single user and is therefor mutable.

Implements blender::bke::GeometryComponent.

Definition at line 32 of file geometry_component_mesh.cc.

References BKE_mesh_copy_for_eval(), MeshComponent(), and blender::bke::Owned.

◆ count_memory()

void blender::bke::MeshComponent::count_memory ( MemoryCounter & memory ) const

overridevirtual

Reimplemented from blender::bke::GeometryComponent.

Definition at line 110 of file geometry_component_mesh.cc.

◆ ensure_owns_direct_data()

void blender::bke::MeshComponent::ensure_owns_direct_data ( )

overridevirtual

Implements blender::bke::GeometryComponent.

Definition at line 99 of file geometry_component_mesh.cc.

References BKE_mesh_copy_for_eval(), BLI_assert, blender::ImplicitSharingInfo::is_mutable(), and blender::bke::Owned.

Referenced by blender::bke::modifier_modify_mesh_and_geometry_set(), and blender::modify_mesh().

◆ get()

const Mesh * blender::bke::MeshComponent::get ( ) const

Get the mesh from this component. This method can be used by multiple threads at the same time. Therefore, the returned mesh should not be modified. No ownership is transferred.

◆ get_for_write()

Mesh * blender::bke::MeshComponent::get_for_write ( )

Get the mesh from this component. This method can only be used when the component is mutable, i.e. it is not shared. The returned mesh can be modified. No ownership is transferred.
