Detailed Description

Contains derived data, caches, and other information not saved in files.

Member Data Documentation

bake_materials

std::unique_ptr<bake::BakeMaterialsList> blender::bke::CurvesGeometryRuntime::bake_materials

Stores weak references to material data blocks.

Definition at line 119 of file BKE_curves.hh.

bounds_cache

SharedCache<Bounds<float3> > blender::bke::CurvesGeometryRuntime::bounds_cache

mutable

A cache of bounds shared between data-blocks with unchanged positions. When data changes affect the bounds, the cache is "un-shared" with other geometries. See #SharedCache comments.

check_type_counts

bool blender::bke::CurvesGeometryRuntime::check_type_counts = true

Type counts have to be set eagerly after each operation. It's checked with asserts that the type counts are correct when accessed. However, this check is expensive and shouldn't be done all the time because it makes debug builds unusable in some situations that would be fine otherwise.

curve_offsets_sharing_info

const ImplicitSharingInfo* blender::bke::CurvesGeometryRuntime::curve_offsets_sharing_info = nullptr

Implicit sharing user count for CurvesGeometry::curve_offsets.

evaluated_length_cache

SharedCache<Vector<float> > blender::bke::CurvesGeometryRuntime::evaluated_length_cache

mutable

Cache of lengths along each evaluated curve for each evaluated point. If a curve is cyclic, it needs one more length value to correspond to the last segment, so in order to make slicing this array for a curve fast, an extra float is stored for every curve.

Definition at line 110 of file BKE_curves.hh.

evaluated_normal_cache

SharedCache<Vector<float3> > blender::bke::CurvesGeometryRuntime::evaluated_normal_cache

mutable

Normal direction vectors for each evaluated point.

evaluated_offsets_cache

SharedCache<EvaluatedOffsets> blender::bke::CurvesGeometryRuntime::evaluated_offsets_cache

mutable

evaluated_position_cache

SharedCache<Vector<float3> > blender::bke::CurvesGeometryRuntime::evaluated_position_cache

mutable

Cache of evaluated positions for all curves. The positions span will be used directly rather than the cache when all curves are poly type.

Definition at line 96 of file BKE_curves.hh.

Referenced by blender::bke::CurvesGeometry::evaluated_positions(), and blender::bke::CurvesGeometry::tag_positions_changed().

evaluated_tangent_cache

SharedCache<Vector<float3> > blender::bke::CurvesGeometryRuntime::evaluated_tangent_cache

mutable

Direction of the curve at each evaluated point.

nurbs_basis_cache

SharedCache<Vector<curves::nurbs::BasisCache> > blender::bke::CurvesGeometryRuntime::nurbs_basis_cache

mutable

type_counts

std::array<int, CURVE_TYPES_NUM> blender::bke::CurvesGeometryRuntime::type_counts

The cached number of curves with each type. Unlike other caches here, this is not computed lazily, since it is needed so often and types are not adjusted much anyway.
