示例1: updateMatrix

  public updateMatrix(camera: Camera | PerspectiveCamera | OrthographicCamera) {
    mat4.identity(this.modelViewMatrix);

    if (this.matrixAutoUpdate) {
      // Reset
      mat4.identity(this.localMatrix);
      mat4.identity(this.modelMatrix);
      quat.identity(this.quaternion);

      // If Object3D has a parent, copy the computed modelMatrix into localMatrix
      if (this.parent) {
        mat4.copy(this.localMatrix, this.parent.modelMatrix);
        mat4.multiply(this.modelMatrix, this.modelMatrix, this.localMatrix);
      }

      // Use lookAt quat as base
      // Note: this.rotation isn't updated if lookAt's used
      quat.copy(this.quaternion, this.quaternionLookAt);

      // Apply local transitions to modelMatrix
      mat4.translate(this.modelMatrix, this.modelMatrix, this.position.v);
      quat.rotateX(this.quaternion, this.quaternion, this.rotation.x);
      quat.rotateY(this.quaternion, this.quaternion, this.rotation.y);
      quat.rotateZ(this.quaternion, this.quaternion, this.rotation.z);
      axisAngle = quat.getAxisAngle(quaternionAxisAngle, this.quaternion);
      mat4.rotate(
        this.modelMatrix,
        this.modelMatrix,
        axisAngle,
        quaternionAxisAngle
      );
      mat4.scale(this.modelMatrix, this.modelMatrix, this.scale.v);
    }

    // Model View Matrix
    if (camera) {
      mat4.multiply(
        this.modelViewMatrix,
        camera.worldInverseMatrix,
        this.modelMatrix
      );

示例2:

outStr = mat4.str(mat4A);
outVal = mat4.frob(mat4A);
outMat4 = mat4.add(outMat4, mat4A, mat4B);
outMat4 = mat4.subtract(outMat4, mat4A, mat4B);
outMat4 = mat4.sub(outMat4, mat4A, mat4B);
outMat4 = mat4.multiplyScalar (outMat4, mat4A, 2);
outMat4 = mat4.multiplyScalarAndAdd (outMat4, mat4A, mat4B, 2);
outBool = mat4.exactEquals(mat4A, mat4B);
outBool = mat4.equals(mat4A, mat4B);

// quat
var deg90 = Math.PI / 2;
outQuat = quat.create();
outQuat = quat.clone(quatA);
outQuat = quat.fromValues(1, 2, 3, 4);
outQuat = quat.copy(outQuat, quatA);
outQuat = quat.set(outQuat, 1, 2, 3, 4);
outQuat = quat.identity(outQuat);
outQuat = quat.rotationTo(outQuat, vec3A, vec3B);
outQuat = quat.setAxes(outQuat, vec3A, vec3B, vec3A);
outQuat = quat.setAxisAngle(outQuat, vec3A, Math.PI * 0.5);
outVal = quat.getAxisAngle (outVec3, quatA);
outQuat = quat.add(outQuat, quatA, quatB);
outQuat = quat.multiply(outQuat, quatA, quatB);
outQuat = quat.mul(outQuat, quatA, quatB);
outQuat = quat.scale(outQuat, quatA, 2);
outVal = quat.length(quatA);
outVal = quat.len(quatA);
outVal = quat.squaredLength(quatA);
