You'd need a *hell* of a lot of RAM to store a mesh of anything 
approaching the necessary resolution - and you'd waste time and space 
computing high-resolution data for parts of the model that are occluded 
or very distant.

Plain ordinary sphere tracing avoids both of these problems. But that's 
designed to work for isosurfaces of arbitrary functions. I'm wondering 
if there's some way we can use the specific characteristics of this 
function to make the process faster. (E.g., it's iterative, it's a known 
polynomial, etc.)
