anaglyph Filter`


Is it possible to use anaglyph filter in unity for games?


yes it is possible and someone already did it. try this script:

See this question.

The short answer is that the most effective ways to do it require Unity pro and would be applied as a full-screen image effect or would use RenderTextures or if you want to leverage an external library would be done as a plug-in(Pro/Mobile only). It can probably be faked in Unity free with a smartly written shader which creates the cyan and magenta offsets based on the depth in the scene.
