Methods

`Static`applyDisplacement

applyDisplacement(obj: Object3D, deltaP: Vector3D): void
Applies positional displacement to the target Object3D.
Parameters
- obj: Object3D
  Target Object3D.
- deltaP: Vector3D
  Displacement vector.
Returns void
- Defined in physix/solvers/EulerIntegrator.ts:62

`Static`integrateAngular

integrateAngular(obj: Object3D, fluidAngularDrag: number, dt: number): void
Integrates torque, angular acceleration, angular velocity, and updates object rotation.
Parameters
- obj: Object3D
  Target Object3D.
- fluidAngularDrag: number
  Damping multiplier from fluid submersion (1.0 = no fluid).
- dt: number
  Substep delta time in seconds.
Returns void
- Defined in physix/solvers/EulerIntegrator.ts:74

`Static`integrateVelocity

integrateVelocity(
    obj: Object3D,
    gravity: Vector3D,
    fluidLinearDrag: number,
    dt: number,
    outDeltaP: Vector3D,
): void
Integrates linear forces, acceleration, and velocity, returning the computed positional displacement.
Parameters
- obj: Object3D
  Target Object3D.
- gravity: Vector3D
  Global gravity vector.
- fluidLinearDrag: number
  Damping multiplier from fluid submersion (1.0 = no fluid).
- dt: number
  Substep delta time in seconds.
- outDeltaP: Vector3D
  Output vector receiving the computed position displacement (v * dt).
Returns void

interpolateTransform(
    obj: Object3D,
    alpha: number,
    truePos: Vector3D,
    trueRot: Vector3D,
    blendPos: Vector3D,
    blendRot: Vector3D,
): void
