i cannot comment (not enough rep), post answer.

you took example original js fiddle: http://jsfiddle.net/eskel/g593q/5/ , removed composer. composer ads few operations in rendering process. 

composer.addpass normal composer.addpass mask composer.addpass outline composer.addpass clearmask composer.addpass copypass
  • first renders object scene, outline scene , mask scene.
  • then makes mask onto renders outline, , clears mask. part creates outline , important step make. why? because if take code , add object, see outline obscured both objects. happens regardles if second object in front or in of scene, sure don't want happen. example: http://jsfiddle.net/adrian_moisa/84470k4n/1/
  • lastly copies outline over rendered scene.

my advice fork original example , keep composer intact. in case don't work, remember include following scripts original example. if of these go missing in action have broken composer, means page won't render.

  • shaderpass.js
  • renderpass.js
  • maskpass.js
  • effectcomposer.js
  • copyshader.js
  • additiveblendshader.js
