Sphere Projection Proof of concept
Disclaimer: I don't take credit for the original idea of science on a sphere produced by NOAA. I am using this original idea to learn how to implement it in unreal engine for educational purposes. You can find out more about Science on a Sphere here: https://sos.noaa.gov/
This last Friday I finally saw the science on a sphere room in the building I teach in.
It currently doesn't work for some reason...
I thought the setup was cool with 4 projectors around a center sphere to project onto. I set out over the last day to get a proof of basic functionality.
what is happening:
A video is played on a texture which is applied to a material on a sphere. Then I have 4 scene capture component 2D around the sphere to get what needs to be projected onto the sphere.
in the level blueprint I have a custom blueprint node that gets the size of each monitor and adds the width of each together to make the viewport span across all displays.
Lastly, I made a Widget Blueprint which is anchored to the edges of the viewport. on the far left is a menu on the main display to adjust the rotation, location, focal length, ext. to get the displays calibrated. To the right of that the cameras are evenly dispersed across the rest of the projectors.
