Higher order function producing a function to perform a raymarch using the provided scene function and options to configure the raymarch process itself.
Returns an AST function which takes 2 args: ray origin, normalized ray direction and returning a 2D vector of:
x = the signed distance to the scene defined SDF surface
y = user data provided by scene (e.g. material ID)
The scene function itself takes a 3D point as input and returns a vec2 with the same component meaning as above.
