Download Retinal Rivalry Blend File Here.

I read up on all this stuff for retinal rivalry when looking at things through Anaglyph (Red-Blue) 3D Glasses. Retinal Rivalry is when colours look dark in one eye and bright in the other, leading to eye strain and maybe even swine flu.

In any case I found this article on a Dubois algorithm that they use on YouTube for 3d content. This basically turns you colour spectrum to a bunch of greys, yellows and purples - the only colours that don’t clash when wearing anaglyph glasses.

Here’s a picture of a standard set of colours and its Dubois counterpart.

I’ll put up more details on how I got these colours soon. I actually used Blender to seperate the colours and reconfigure them this way.

Check this out:

Method One

Pixels in a standard image are made out of a mixture Red, Green and Blue elements. The easiest way to deal with how to remix the colours for 3d colour safe is to disregard the Red channel altogether and replace it with a mixture of its Green and Blue elements put together and fed back into its Red component.

The problem is it doesn’t actually deal with the colour Red and pure Red can appear Black.

See? No?

So here’s the solution, and of course it’s more complicated.

Solution

Basically the full colour image has its Red, Green and Blue information multiplied and combined 3 times.

Here’s the blend file for the Retinal Rivalry thing available here.

Getting it to work is a simple process.

shows you how to do it. Go through the steps slowly and carefully one at a time and you’ll get there. Once I had it going my iPhone and Mac were talking just fine.

Got back into making stuff for the iPhone. The Macbook’s hard drive packed it in on me so I’ve had to start all over again, but this is what I’ve learned so far…

iPhone is not being seen by either iTunes or Xcode

Error E8000001

Just try and reset your iPhone, that’s what worked for me. Resetting your computer will help too.

Next step, getting the certificate stuff to work.

This makes the texture renders normals on the map input with sphere mapping, this gives the impression of multiple directional brush strokes.

I also used a toon shader to create more definition within colours. This works well with the normals streaks.
