Marching.js is a JavaScript library that compiles GLSL ray marchers.

module.exports = `march(
  Repeat(
    StairsDifference(
      Sphere(2),
      Repeat( Sphere( .1 ), .25 ),
      .25,
      10
    ),
    6
  ).translate( 0,-1.5 ),
  Plane().texture( 'cellular', { strength:-.5, scale:10 })
)
.fog( .1, Vec3(0,0,.25) )
.background( Vec3(0,0,.25) )
.render()

select code and hit ctrl+enter to  
execute. alt+enter (option+enter on 
a mac) executes a block of code.   
ctrl+shift+g toggles hiding         
the gui/code. try the other demos  
using the menu in the upper right 
corner. when you're ready to start 
coding go through the tutorials     
found in the same menu. Click on   
the help link for a reference.       
                                   
For a nice intro on ray marching and
signed distance functions,which are
the techniques used by marching.js,
