rotate method
dynamic
rotate(
- dynamic axis,
- dynamic angle
- Rotate the camera around an axis passing by trackball's center
- @param {Vector3} axis Rotation axis
- @param {number} angle Angle in radians
- @returns {Object} Object with 'camera' field containing transformation matrix resulting from the operation to be applied to the camera
- @param {Vector3} axis Rotation axis
Implementation
rotate(axis, angle) {
var point = this._gizmos.position; //rotation center
this._translationMatrix.makeTranslation(-point.x, -point.y, -point.z);
this._rotationMatrix.makeRotationAxis(axis, -angle);
//rotate camera
this._m4_1.makeTranslation(point.x, point.y, point.z);
this._m4_1.multiply(this._rotationMatrix);
this._m4_1.multiply(this._translationMatrix);
this.setTransformationMatrices(this._m4_1);
return _transformation;
