It calculates the scattering based on real-space description of a particle.\n\nBasically, define your SLD as a function of either cartesian or polar coordinates and click scatter\n\n  def sld(x,y,z)\n  def sld(r,theta,phi)\n\nThe display on the right shows your particle, both as a total projected density (top) and as a slice (bottom).\n\nThis is a minimal working system. Currently magnetism doesn\'t work, neither do extra parameters for your functions,\nnor structure factors, nor fitting, nor 2D plots.\n\nHere\'s a simple example: """\n\ndef sld_cube(x,y,z):\n    """ A cube with 100Ang side length"""\n\n    return rect(0.02*x)*rect(0.02*y)*rect(0.02*z)\n\n\ndef sld_sphere(r, theta, phi):\n    """ Sphere r=50Ang"""\n\n    return rect(0.02*r)\n\nsld = sld_sphere\n\n'
