Projecting a simple game I made onto a dome for neuroscience experiments

Hi all,

I made a simple game where you can move down a corridor as the first person perspective. It is all good when showing on a PC screen but I want to project what I can see now onto a semispherical dome (see pic attached). The projector is below the dome and a mirror reflects the image hence projects it onto the dome. I have a mesh map with the corresponding angular coordinates to the x,y coordinates (an excel sheet). I am quite new to Unity and not sure how the projection can be done.

Any help is much appreciated.

Anyi

Perhaps this article by Paul Bourke may help.

Hi JoeStrout,

Thanks a lot for the recommendation! Although I think this might be an overkill: ideally I only need a mesh map that covert all the points in unity space to the angular coordinates on the dome. Because the subject will maintain a fixed distance to any given point on the dome and one camera should be enough. We have a mesh map already that tells you what x and y (on image or video that will be displayed) are corresponding to what azimuth and elevation inside the dome. And finally the ‘first person perspective game’ should move along as the mouse scroll down (or have some other metric input such as how far a wheel has run).

I was thinking just put a mesh map in between the game that is saved as a scene, and the final output to a projector. I am pretty new to unity and have not made myself very clear, apologies!
