Pulga Springs Force#
Functionality#
This node creates a force to be applied with the [Pulga Physics->Pulga Physics Solver] node.
The springs are defined as edges indices.
The force direction the direction of the edge.
The force magnitude will be: (Spring Length - Spring Rest Length) * Stiffness
Input#
Springs: Edges Indices referring to the particle system vertices.
Stiffness: Stiffness of the springs, if multiple values are given the will be use as stiffness per spring.
Rest Length: Springs rest length, if set to 0 the rest length will be calculated from the initial position.
Clamp: Constrain maximum difference each iteration. If set to 0 no clap will be applied
