4×4 matrices.

Members ​

Member Kind Summary
identity method The identity matrix.
compose method The matrix of a pose; omitted fields are identity.
decompose method The pose of a matrix, with one rotation (a quaternion); a mirroring matrix puts its −1 on scale.x, and a sheared one decomposes approximately, as Pose.scale says.
multiply method a × b: b applies first.
invert method The inverse, or null when m can't be inverted.

Declaration ​

ts
export const mat4: {
  identity(): Mat4;
  compose(pose: PoseInput): Mat4;
  decompose(m: Mat4): {
    position: Point3;
    quaternion: Quat;
    scale: Point3;
  };
  multiply(a: Mat4, b: Mat4): Mat4;
  invert(m: Mat4): Mat4 | null;
};

Rule Result
1. Neutral name pass: mat4 names no product
2. A precedent not recorded: no ledger row (coverage.json) names this member or its owner
3. Two apps, or labs not recorded: no ledger row names this member or its owner
4. The cheaper fix first not recorded per member (Appendix B decides it per need)
