RBF Nodes for Blender v1.3.0

RBF Nodes 是一款基于节点的 RBF 求解器，适用于 Blender。它允许使用多个驱动值来驱动多个属性。

RBF 代表径向基函数（Radial Basis Function），用于在任意定义的采样点上逼近或插值给定的值集。RBF 具有广泛的应用，在常规驱动值方式在 3D 动画中失效时非常有用。它基本上允许用户基于一组采样值或由艺术家预先定义的姿势来插值多个值。对于标准驱动器来说，这种多值插值不容易实现，甚至是不可能的。例如，Blender 中的驱动器可以有多个输入值，但只有一个输出目标。RBF 可以基于多个输入值求解多个输出值。

RBF Nodes 拥有自己的节点树，使其独立于任何模式和面板。尽管 RBF 通常用于绑定以驱动某些变形效果，但仅将其限制在骨骼上是一种浪费。因此，您可以将其与物体、骨骼、着色器和几何节点结合使用，这使其非常通用。

RBF Nodes is a node‑based RBF solver for Blender. It allows you to drive multiple properties with multiple driver values.

RBF stands for Radial Basis Function and is used to approximate or interpolate a given set of values at any defined sample point. RBFs have a wide range of applications and can be very helpful when regular ways of driving values fail in 3D animation. It basically allows the user to interpolate multiple values based on a set of sample values, or poses, which are defined by the artist in advance. For standard drivers, such multi‑value interpolation is not easily, or even impossible, to achieve. For example, a driver in Blender can have multiple input values but only one output target. RBFs can solve multiple output values based on multiple input values.

RBF Nodes has its own node tree to make it independent from any modes and panels. Even though RBFs are commonly used for rigging to drive certain deformation effects, it would be a waste to limit it only to armatures. Therefore, you can use it with objects, armatures, shaders, and geometry nodes, which makes it very versatile.
