Experiment: zooming waaay out #179

Open pkgw opened 2 years ago

pkgw commented 2 years ago

@astrodavid10 is curious about ways to zoom out farther than the current FOV limit of 60°. The distortions are going to get really gnarly, but I'd be curious to see what happens if you just hard-code a FOV bigger than that limit with the current engine. CC @Carifio24.

Thanks for trying! See #24 for additional discussion.

The trig breaks down completely at some point for the projection matrix and you just can't increase the FOV without breaking. To get super wide views you have to use multiple rendering passes and then use a warp projection to get them all in the same screen, like the single full dome mode.
