所作近似弧长参数化曲线在插值节点处，近似弧长是精确的，并且具有与精确弧长参数曲线同方向的单位切矢。

At any knots, the nearly arc length are precise for the resulting nearly arc length parametric curve, and it has the unit tangent same as that of the real arc length parametric curve.

重心插值公式具有计算量小、数值计算稳定性好和增加新的插值节点不需重新计算原有插值节点基函数的优点。

The advantages of barycentric interpolation formulations in computation are small number of floating point operations (flops) and good numerical stability.

But a real key in looking at these plots is where we, in fact, did go through zero and have this zero probability density.

是我们经历这些零值,而且有这些零概率密度,我们把它叫做节点。

So that means this node 1 will have an index of 1.

所以这意味着,这个节点索引值将会为。

For an angular node, we're just talking about what the l value is, so whatever l is equal to is equal to the number of angular nodes you have.

对于角向节点，我们其实就是在讨论l，的值是多少，因此不管，l，的值等于几,它就等于你所有的角向节点的数目。
