Syntax

public struct ufbx.ufbx_nurbs_basis

Fields

is_2d

true if this axis is two-dimensional.

Declaration

public bool is_2d

Field Value

Type	Description
bool

knot_vector

Subdivision of the parameter range to control points.

Declaration

public ufbx.ufbx_real_list knot_vector

Field Value

Type	Description
ufbx.ufbx_real_list

num_wrap_control_points

Number of control points that need to be copied to the end. This is just for convenience as it could be derived from topology and order. If for example num_wrap_control_points == 3 you should repeat the first 3 control points after the end. HINT: You don't need to worry about this if you use ufbx functions like ufbx_evaluate_nurbs_curve() as they handle this internally.

Declaration

public ulong num_wrap_control_points

Field Value

Type	Description
ulong

order

Number of control points influencing a point on the curve/surface. Equal to the degree plus one.

Declaration

public uint order

Field Value

Type	Description
uint

spans

Parameter values of control points.

Declaration

public ufbx.ufbx_real_list spans

Field Value

Type	Description
ufbx.ufbx_real_list

t_max

Declaration

public float t_max

Field Value

Type	Description
float

t_min

Range for the parameter value.

Declaration

public float t_min

Field Value

Type	Description
float

topology

Topology (periodicity) of the dimension.

Declaration

public ufbx.ufbx_nurbs_topology topology

Field Value

Type	Description
ufbx.ufbx_nurbs_topology

valid

true if the parametrization is well defined.

Declaration

public bool valid

Field Value

Type	Description
bool
