Detailed Description

Versioned create-info struct for B-spline surface construction.

Poles are stored row-major: index = u * v_pole_count + v. U and V knot sequences are each in compact form (distinct + multiplicities).

Member Data Documentation

◆ is_u_periodic

int32_t occtl_surface_bspline_create_info::is_u_periodic

0/1.

◆ is_v_periodic

int32_t occtl_surface_bspline_create_info::is_v_periodic

0/1.

◆ p_next

const void* occtl_surface_bspline_create_info::p_next

Reserved; must be NULL.

◆ poles

const occtl_point3_t* occtl_surface_bspline_create_info::poles

[in] Borrows it; row-major: index = u*v_pole_count + v.

◆ struct_version

uint32_t occtl_surface_bspline_create_info::struct_version

Must be OCCTL_SURFACE_BSPLINE_CREATE_INFO_VERSION_1.

◆ u_knots

const double* occtl_surface_bspline_create_info::u_knots

[in] Borrows it; distinct U knot values.

◆ u_multiplicities

const int32_t* occtl_surface_bspline_create_info::u_multiplicities

[in] Borrows it; count = u_knot_count.

◆ u_pole_count

size_t occtl_surface_bspline_create_info::u_pole_count

Number of poles in the U direction.

◆ v_knots

const double* occtl_surface_bspline_create_info::v_knots

[in] Borrows it; distinct V knot values.

◆ v_multiplicities

const int32_t* occtl_surface_bspline_create_info::v_multiplicities

[in] Borrows it; count = v_knot_count.

◆ v_pole_count

size_t occtl_surface_bspline_create_info::v_pole_count

Number of poles in the V direction.

◆ weights

const double* occtl_surface_bspline_create_info::weights

[in] Borrows it; NULL = non-rational; same layout as poles.
