I challenge anyone to not like the Innerspace movie!
There’s a lot of new (to me) lighting effects in this shader. The headlights of the ‘pod’ are light cones with analytically solved ray start/end points, used to calculate the amount of ‘glow’ to apply.
I also make heavy use of domain repetition (where you use math to ‘duplicate’ regions of space) to make a whole stream of blood cells using only three modelled originals.
This is one of my longer shaders, running in at just under a minute.
The GLSL shader source can be found here.
