#include <DNA_curves_types.h>
Inherited by blender::bke::CurvesGeometry.
A reusable data structure for geometry consisting of many curves. All control point data is stored contiguously for better efficiency when there are many curves. Multiple curve types are supported, as described in CurveType. Data for each curve is accessed by slicing the main point_data arrays.
The data structure is meant to separate geometry data storage and processing from Blender focused ID data-block handling. The struct can also be embedded to allow reusing it.

| int* CurvesGeometry::curve_offsets |
The start index of each curve in the point data. The size of each curve can be calculated by subtracting the offset from the next offset. That is valid even for the last curve because this array is allocated with a length one larger than the number of curves. This is allowed to be null when there are no curves.
Every curve offset must be at least one larger than the previous. In other words, every curve must have at least one point. The first value is 0 and the last value is point_num.
This array is shared based on the bke::CurvesGeometryRuntime::curve_offsets_sharing_info. Avoid accessing directly when possible.
