Detailed Description

When the original data is in some edit mode, we want to propagate some additional information through object evaluation. This information can be used by edit modes to support working on evaluated data.

This component is added at the beginning of modifier evaluation.

Member Function Documentation

clear()

void blender::bke::GeometryComponentEditData::clear ( )

overridevirtual

Remove referenced data from the geometry component.

Implements blender::bke::GeometryComponent.

Definition at line 40 of file geometry_component_edit_data.cc.

copy()

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

finalvirtual

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

Implements blender::bke::GeometryComponent.

ensure_owns_direct_data()

void blender::bke::GeometryComponentEditData::ensure_owns_direct_data ( )

finalvirtual

Implements blender::bke::GeometryComponent.

Definition at line 35 of file geometry_component_edit_data.cc.

owns_direct_data()

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

finalvirtual

Implements blender::bke::GeometryComponent.

remember_deformed_positions_if_necessary()

void blender::bke::GeometryComponentEditData::remember_deformed_positions_if_necessary ( GeometrySet & geometry )

static

The first node that does topology changing operations on curves should store the curve point positions it retrieved as input. Without this, information about the deformed positions is lost, which would make curves sculpt mode fall back to using original curve positions instead of deformed ones.

Member Data Documentation

curves_edit_hints_

std::unique_ptr<CurvesEditHints> blender::bke::GeometryComponentEditData::curves_edit_hints_

Information about how original curves are manipulated during evaluation. This data is used so that curve sculpt tools can work on evaluated data. It is not stored in CurveComponent because the data remains valid even when there is no actual curves geometry anymore, for example, when the curves have been converted to a mesh.

Definition at line 738 of file BKE_geometry_set.hh.

gizmo_edit_hints_

std::unique_ptr<GizmoEditHints> blender::bke::GeometryComponentEditData::gizmo_edit_hints_

Propagated information for how gizmos should be transformed along with the geometry.

Definition at line 746 of file BKE_geometry_set.hh.

grease_pencil_edit_hints_

std::unique_ptr<GreasePencilEditHints> blender::bke::GeometryComponentEditData::grease_pencil_edit_hints_

Information about how drawings on the grease pencil layers are manipulated during evaluation.

Definition at line 742 of file BKE_geometry_set.hh.
