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.

Definition at line 1188 of file geometry_component_mesh.cc.

References blender::bke::get_mesh_accessor_functions_ref().

◆ attributes_for_write()

std::optional< MutableAttributeAccessor > blender::bke::MeshComponent::attributes_for_write ( )

finalvirtual

Reimplemented from blender::bke::GeometryComponent.

Definition at line 1193 of file geometry_component_mesh.cc.

References blender::bke::get_mesh_accessor_functions_ref().

◆ clear()

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

overridevirtual

Remove referenced data from the geometry component.

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 41 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 119 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 108 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().

◆ 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.
