> Hii, i am new to three.js and i am currently doing move,rotate,and scale on a cube. if i want to move a cube then i use to assign this values i.e cube.position.x and cube.position.y, and the cube move from its position.But i want to move that cube from a particular point like in c# there are methods like RotateAt, ScaleAt which gives us the provision from which point you want to transform your [object.Is](http://object.Is) there are methods like this in three.js beacuse i didn’t find any of this. Thanks & regard…
