Class JiggleBoneSolver

Namespace: ValveResourceFormat.Renderer
Assembly: Renderer.dll

Simulates the jiggle bones of a model as springs in world space after the animation has posed it. A bone points along its local X axis, with yaw about its Z axis and pitch about its Y axis. A bone lags behind its animated pose, and its descendants follow it.

Inheritance

Methods

Create(Model)

Builds the simulation of the jiggle bones in the soft body of a model. Nodes that are not bones of its skeleton are skipped.

public static JiggleBoneSolver? Create(Model model)

Parameters

model Model

The model whose jiggle bones are simulated.

Returns

JiggleBoneSolver?

The simulation, or null when the model has no jiggle bones.

Evaluate(Matrix4x4[], Matrix4x4, float)

Moves the jiggle bones and their descendants in a pose that holds the animated transforms.

public void Evaluate(Matrix4x4[] pose, Matrix4x4 modelToWorld, float timeStep)

Parameters

pose Matrix4x4[]

Model space transforms of the bones.

modelToWorld Matrix4x4

The transform of the model, which gives gravity its direction and the model's own movement its effect.

timeStep float

Seconds since the last evaluation, above zero.
