Cone trace analytic solution
Spherical cap cone analytic solution is a 1d problem, since the cone cap sphere slides along the ray. The intersection point to empty space sphere is always on the ray.
S : radius of cone cap sphere at t=1
r(d) : cone cap sphere radius at distance d
r(d) = d*S
p = distance of current SDF sample
SDF(p) = sdf function result at location p
x = distance after conservative step
