Detailed Description

This class is an abstraction for evaluating NURBS curves.

It accepts an array of vertices, each of which may be in a different coordinate space (as defined by a NodePath), as well as an optional knot vector.

This is not related to NurbsCurve, ClassicNurbsCurve, CubicCurveseg or any of the ParametricCurve-derived objects in this module. It is a completely parallel implementation of NURBS curves, and will probably eventually replace the whole ParametricCurve class hierarchy.

void NurbsCurveEvaluator::recompute_basis (   )  [private]

Recomputes the basis matrices according to the knot vector. Definition at line 273 of file nurbsCurveEvaluator.cxx.

void NurbsCurveEvaluator::recompute_knots (   )  [private]

Creates a default knot vector. Definition at line 236 of file nurbsCurveEvaluator.cxx. Referenced by get_vertex_space().

int ReferenceCount::ref (   )  const [inline, inherited]

Explicitly increments the reference count. User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it. The return value is the new reference count. Definition at line 225 of file referenceCount.I. Referenced by ClientDevice::ClientDevice(), EggGroupNode::find_textures(), EggGroupNode::r_apply_texmats(), EggGroupNode::r_flatten_transforms(), and EggGroupNode::reverse_vertex_ordering().

void NurbsCurveEvaluator::reset (  int  num_vertices  )

Resets all the vertices and knots to their default values, and sets the curve up with the indicated number of vertices. You must then call set_vertex() repeatedly to fill in all of the vertex values appropriately. Definition at line 66 of file nurbsCurveEvaluator.cxx. References _vertices, and nassertr.

void NurbsCurveEvaluator::set_knot (  int  i, float  knot )

Sets the value of the nth knot. Each knot value should be greater than or equal to the preceding value. If no knot values are set, a default knot vector is supplied. Definition at line 111 of file nurbsCurveEvaluator.cxx. References get_vertices().

void NurbsCurveEvaluator::set_order (  int  order  )  [inline]

Sets the order of the curve. This resets the knot vector to the default knot vector for the number of vertices. The order must be 1, 2, 3, or 4, and the value is one more than the degree of the curve. Definition at line 42 of file nurbsCurveEvaluator.I. References _order, and INLINE.

void NurbsCurveEvaluator::set_vertex (  int  i, const LVecBase3f &  vertex, float  weight = 1.0 )  [inline]

Sets the nth control vertex of the curve. Definition at line 103 of file nurbsCurveEvaluator.I. References _vertices, INLINE, and nassertv.

void NurbsCurveEvaluator::set_vertex (  int  i, const LVecBase4f &  vertex )  [inline]

Sets the nth control vertex of the curve. Definition at line 89 of file nurbsCurveEvaluator.I. References _vertices, nassertr, and zero.

void NurbsCurveEvaluator::set_vertex_space (  int  i, const string &  space )  [inline]

Sets the coordinate space of the nth control vertex. If this is not specified, or is set to an empty string, the nth control vertex is deemed to be in the coordinate space passed to evaluate(). This specifies the space as a string, which describes the path to find the node relative to the rel_to NodePath when the curve is evaluated. Definition at line 177 of file nurbsCurveEvaluator.I.

void NurbsCurveEvaluator::set_vertex_space (  int  i, const NodePath &  space )  [inline]

Sets the coordinate space of the nth control vertex. If this is not specified, or is set to an empty NodePath, the nth control vertex is deemed to be in the coordinate space passed to evaluate(). This specifies the space as a fixed NodePath, which is always the same NodePath. Also see setting the space as a path string, which can specify a different NodePath for different instances of the curve. Definition at line 149 of file nurbsCurveEvaluator.I.

void ReferenceCount::test_ref_count_integrity (   )  const [inline, inherited]

Does some easy checks to make sure that the reference count isn't completely bogus. Definition at line 328 of file referenceCount.I. References INLINE. Referenced by EggNode::determine_bin(), and ReferenceCount::~ReferenceCount().

int ReferenceCount::unref (   )  const [inline, inherited]

Explicitly decrements the reference count. Note that the object will not be implicitly deleted by unref() simply because the reference count drops to zero. (Having a member function delete itself is problematic; plus, we don't have a virtual destructor anyway.) However, see the helper function unref_delete(). User code should avoid using ref() and unref() directly, which can result in missed reference counts. Instead, let a PointerTo object manage the reference counting automatically. This function is const, even though it changes the object, because generally fiddling with an object's reference count isn't considered part of fiddling with the object. An object might be const in other ways, but we still need to accurately count the number of references to it. The return value is the new reference count.
