DESCRIPTION 
Monolith is a voxel-based modeling editor. It focusses on the development of new digital representations and design workflows that inhabit the space between traditional computer aided design (CAD) and three dimensional voxel based image processing with the aim of allowing a very fine level of control over volumetric material distributions, especially in light of new multi-material 3D printing technologies.  

PROCEDURE 

1.Set a box as the voxel field; adjust the resolution for a finer result  
2.Define a math function to for the shape of the model 
3.Define a math function for the material distribution  
4.Add the voxel field, shape, and material together  
5.Extract the shape and material channel  
6.Form an iso-mesh of the from shape channel  
7.Preview the mesh with material channel  
8.Preview the voxel field in grasshopper
