◆ is_valid()

bool blender::bke::CurvesEditHints::is_valid ( ) const

The edit hints have to correspond to the original curves, i.e. the number of deformed points is the same as the number of original points.

Member Data Documentation

◆ curves_id_orig

const Curves& blender::bke::CurvesEditHints::curves_id_orig

Original data that the edit hints below are meant to be used for.

Definition at line 529 of file BKE_curves.hh.

Referenced by CurvesEditHints(), blender::bke::crazyspace::get_evaluated_curves_deformation(), is_valid(), blender::nodes::node_geo_deform_curves_on_surface_cc::node_geo_exec(), positions(), positions_for_write(), and blender::bke::remember_deformed_curve_positions_if_necessary().

◆ deform_mats

std::optional<Array<float3x3> > blender::bke::CurvesEditHints::deform_mats

Matrices which transform point movement vectors from original data to corresponding movements of evaluated data.

◆ positions_data

ImplicitSharingPtrAndData blender::bke::CurvesEditHints::positions_data

Evaluated positions for the points in #curves_orig. If this is empty, the positions from the evaluated Curves should be used if possible.
