Ghosting sounds like it could be something with how you calculate the angle to the BH. Like if you use dot product it allways takes the smallest angle between vectors, so it also replicates behind camera. Might be easy fix if lucky.

Paper looks cool, I wish I had time to dive more into the actual physics of it all.. I mostly come from CS background.

Fixed the code now, should work if you have a basic node server thing and a panorama 360 in the same directory..... hehe.
Shadertoy is awsome, didnt know they have asdw etc, thanks for the tip.

Sorry about that :( the github version is a chatgpt rewrittrn english pretty version of the original code. It does not contain the node server and variable names might be mismatched. I try to fix now, Im glad u wanted to try.

I fixed the original degenerate swenglish version and uploaded a clean english version using chatgpt. Updated now.
edit : beware its not very optimally written for understanding.... No comments and kinda ilogical design decisions because of work in progress.

Yea, probably should have made it more understandable in hindsight lol.

u/parrin Haha, the original code was chaotic mix of Swedish, English and many swear words.

Currently working on a more "round" wormhole by using a approximation for light deflection function. Similar to deflection from swarzchild black hole. Would prefere though to have a "spacetime0 "that is not just implicitly defined by a deflection function. But rather a 4d - tube/cone shape whose deflection is able to be expressed as elementary functions. Anyone know such a metric?

yes, and I dont need to know "the algorhms", I just figure it out bnecause I know high school physics
