How does Bitmoji work? : <p>does anyone have an idea, how bitmoji or other similar services work? I have an idea for an app, which should have custom Avatars. </p>

<p>There are multiple libraries for 3D-Games, which are based on Morphing. Easy. All the 2D-Characters however are seamingly made with sprites. But if you consider how many options bitmoji has, do you think, they basically have drawn all the possible sprites? Or am I to stupid to find the "yellow brick road"?</p>

<p>Thanks for any advice.</p>
