Wow, this is sick!! Clearly you understand the maths better than I did. :) Mad kudos. Would love to collab sometime.
Sure! Im trying to build out systems for a game, and my spaghetti stuck to the wall eventually for the nebulae. But thanks for the compliment!
ive been working on adding in reflection nebula (regular scatter in distant rather than lots of ionization, often blue in photos), herbig-haro up close, protoplanetary and postplanetary material rings, and active black hole with occluding clouds.
