Sim Daltonism for Mac and iOS
Sim Daltonism is a color blindness simulator for iOS and Mac. It takes a live video feed from the camera on iOS and filters it in real time using a color blindness simulation algorithm.
The Mac version has a filter window that shows the content underneath the window filtered.
The application is almost a clone of Red Stripe where the filter
algorithm has been replaced with an OpenGL adaptation of the
live filtering code is taken in part from the RosyWriter sample code
provided by Apple.
This application shares a lot with my other app Red Stripe. Note that contribution accepted in Sim Daltonism will often land into Red Stripe too, which is closed source.

A note about that license
The copyright for the original color blindness simulation algorithm is shared by Matthew Wickline and the Human-Computer Interaction Resource Network. It seems the HCIRN is not reachable anymore, and it probably no longer exists. Because of this, Matthew Wickline decided to to change the license to something he believed would reflect the original intent of the HCIRN. But it is possible that someone still owns the HCIRN copyright, which would make that license change legally contestable.
So I am relying solely on the older non-commercial clause for distributing this app.
If you distribute a derived work that does not include the color blindness
simulation algorithm derived from
color_blind_sim, then you only have to
follow the terms of the Apache License 2.0.
