Animation has changed and grown drastically over the years. While it has evolved in terms of drawing, technology does have a large part to play in it. Old characters were required to be hand-drawn frame by frame, a larger version of the flipbook if you must. These days there are computers and animation software to help you not only create the characters but also animate them.
With the different programs, you can now create 2D and even 3D characters with a few clicks. So, if you don’t have any background in drawing or sketching, that’s okay too. Simply create your characters with different polygons and shape them as you see fit.
