You can also doing this using the built-in cube in the polyhedra module. Polyhedra can be rescaled and translated; this does something close to what it looked like you were trying:
sage: c = polytopes.n_cube(3) sage: c2 = c*2 sage: p = point((2/3,2/3,0),color='green',size=10) sage: c3 = (1/3)*c + vector([2/3,2/3,0]) sage: combo = p + c2.render_solid(opacity=0.1, rgbcolor='red') sage: combo += c3.render_solid(opacity=0.8, rgbcolor='blue') sage: show(combo) -Marshall Hampton On Jan 29, 11:47 am, Loïc <xl...@free.fr> wrote: > Hello list, > > I was making some tries with 3D. > I don't succeed to make cube correctly: > Here is my code: > > c=cube((0,0,0),size=2,opacity=0.1,color='red') > c+=point((2/3,2/3,0),color='green',size=10) > c+=cube(center=(2/3,2/3,0),size=1/3,opacity=0.8) > show(c) > > I draw a point with coord (2/3,2/3,0) > Then I draw a cube centered on this point with size 1/3 > > When I display with JMol, the point is outside the cube... > > Is it a bug ?
