Detailed Description

A geometry component that stores a group of curves, corresponding the Curves data-block and the CurvesGeometry type. Attributes are stored on the control point domain and the curve domain.

Member Function Documentation

◆ attributes()

std::optional< AttributeAccessor > blender::bke::CurveComponent::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 313 of file geometry_component_curves.cc.

◆ attributes_for_write()

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

finalvirtual

Reimplemented from blender::bke::GeometryComponent.

Definition at line 319 of file geometry_component_curves.cc.

◆ clear()

void blender::bke::CurveComponent::clear ( )

overridevirtual

Remove referenced data from the geometry component.

Implements blender::bke::GeometryComponent.

Definition at line 45 of file geometry_component_curves.cc.

◆ copy()

GeometryComponentPtr blender::bke::CurveComponent::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 35 of file geometry_component_curves.cc.

◆ count_memory()

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

overridevirtual

Reimplemented from blender::bke::GeometryComponent.

Definition at line 120 of file geometry_component_curves.cc.

◆ ensure_owns_direct_data()

void blender::bke::CurveComponent::ensure_owns_direct_data ( )

overridevirtual

Implements blender::bke::GeometryComponent.

Definition at line 109 of file geometry_component_curves.cc.

◆ get()

const Curves * blender::bke::CurveComponent::get ( ) const

Definition at line 84 of file geometry_component_curves.cc.

◆ get_curve_for_render()

const Curve * blender::bke::CurveComponent::get_curve_for_render ( ) const

Create empty curve data used for rendering the spline's wire edges.

Note: See comment on #curve_for_render_ for further explanation.

Definition at line 127 of file geometry_component_curves.cc.

◆ get_for_write()

Curves * blender::bke::CurveComponent::get_for_write ( )

Definition at line 89 of file geometry_component_curves.cc.

◆ has_curves()

bool blender::bke::CurveComponent::has_curves ( ) const

Definition at line 63 of file geometry_component_curves.cc.

◆ is_empty()

bool blender::bke::CurveComponent::is_empty ( ) const

finalvirtual

Reimplemented from blender::bke::GeometryComponent.

Definition at line 99 of file geometry_component_curves.cc.

◆ owns_direct_data()

bool blender::bke::CurveComponent::owns_direct_data ( ) const

overridevirtual

Implements blender::bke::GeometryComponent.

Definition at line 104 of file geometry_component_curves.cc.

◆ release()

Curves * blender::bke::CurveComponent::release ( )

Definition at line 76 of file geometry_component_curves.cc.

◆ replace()

void blender::bke::CurveComponent::replace	(	Curves *	curve,
		GeometryOwnershipType	ownership = GeometryOwnershipType::Owned )

Clear the component and replace it with the new curve.
