Enum JointAnchor

pub enum JointAnchor {
    Local(Vector),
    FromGlobal(Vector),
}

The translation of a JointFrame, defining the anchor point where the bodies are attached to each other.

Each joint anchor is stored in local space relative to the transform of the body it is attached to. This way, the initial configuration of the joint is preserved even when the body is moved.

The initial anchor can also be specified in world space using JointAnchor::FromGlobal, but it is automatically converted to JointAnchor::Local during the next simulation step.

By default, a local anchor of zero is used, and the anchor aligns with the body transform.

Variants

Local(Vector)

The anchor point is specified in local coordinates relative to the body transform.

FromGlobal(Vector)

The anchor point is specified in global coordinates.

Implementations

impl JointAnchor

pub const ZERO: Self

The anchor point at the local origin.

This represents an anchor that aligns with the body transform.

pub fn compute_local( anchor1: Self, anchor2: Self, pos1: Vector, pos2: Vector, rot1: &Rotation, rot2: &Rotation, ) -> [Self; 2]

Computes JointAnchor::Locals for the given JointAnchors corresponding to the transforms of two bodies constrained by a joint.
