Full screen curve/strech effect for driving simulator

Hello,

Quick question! We are hoping to use Unity to create a driving simulator, which will be projected onto a large curved screen using three projectors. We want to curve the image on the projected screen, otherwise the perspective will be off. Does anyone know if this effect could be achieved using OnRenderImage and post-processing?

The ideal effect is three curves, achieved by stretching the screen image. I've attached a screen shot to illustrate.

I've also found this plugin: https://www.assetstore.unity3d.com/en/#!/content/26165 , but I believe it can only achieve one curve per scene. We would like to curve one way, and then back the other.

Thank you!

 

Hello,

As a progress report, we did figure out how to do something similar with a post-processing effect. Image attached. Probably still needs some changes. We'll see how it looks on the screen. ​
