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
Implementation
rotate(axis, angle) {
var point = _gizmos.position; //rotation center
_translationMatrix.makeTranslation(-point.x, -point.y, -point.z);
_rotationMatrix.makeRotationAxis(axis, -angle);
//rotate camera
_m4_1.makeTranslation(point.x, point.y, point.z);
_m4_1.multiply(_rotationMatrix);
_m4_1.multiply(_translationMatrix);
setTransformationMatrices(_m4_1);
return _transformation;
