It is done with distance fields (distance from a point to a primitive), constant-steps (typically used with volume rendering), and root-finders (a math approach). Normally, creating a scene like this requires tools for geometry (Maya, Blender, 3DsMax), tools for textures (Photoshop, Gimp, MSPaint). easy frappe
