Today we are going to go back to the practical lessons for html5. I think we have already done a good break in our lessons. In this tutorial I will show you how to create a pane for drawing which is spinning on its axis (on html5 canvas object). Each of your drawn shape will be spinning in pseudo 3D mode. Two objects (prototypes) are defined here: Point and Shape (each shape consists of multiple points). The main idea – to project and be rotated points of figures, as well as to draw a curved line between these points.
