+StereoscopicEffects for three.js
+================================
+
+This module provides effects to display a 3D scene created with threeJS in **stereoscopy** (multiple methods)
+
+What does it mean?
+------------------
+
+Displaying 3D scenes with threeJS is very nice, but displaying them so that the users can view them with depth is even better.
+As humans, we have a strong depth perception based on the slight differences of parallax perceived by our eyes.
+In threeJS, the StereoCamera allows to mimic the perception of each eye independantly, but the rest of the work is up to the develpper.
+
+Furthermore, there exist tens of methods to display stereoscopic content.
+Each one has its pro and cons, and displaying one or another depends on which apparatus the user uses or prefers.
+The best is thus to let the users choose their display mode.
+
+This module allows to display in a lot of methods easily.
+
+Which methods are supported?
