sphere3d

Arguments:

  • radius,_nb_recursions!=0    or
  • radius,_nb_phi>=3,_nb_theta>=3

Description:

Input 3D sphere at (0,0,0), with specified geometry.
If 2 arguments are specified:
If nb_recursions>0, the sphere is generated using recursive subdivisions of an icosahedron.
If nb_recursions<0, the sphere is generated using recursive subdividions of a cube.
If 3 arguments are specified, the sphere is generated using spherical coordinates discretization.

Default values:

nb_recursions=3.

Example of use:

sphere3d 100 +primitives3d 1 color3d[-2] ${-rgb}

Command: sphere3d 100 +primitives3d 1 color3d[-2] ${-rgb}
Command: sphere3d 100 +primitives3d 1 color3d[-2] ${-rgb}
