New Plotting Examples

Try running examples/plotting.py in an interactive shell:



Other updates:

• New experimental option 'use_lambda', which speeds up calculation by an order of magnitude (used in most of the examples, but doesn't work in every case yet).
  


• Custom coloring can be applied in real-time:
  >>> p[1].color = 0.3,0.3,0.9 # any solid color
  >>> p[1].color = 'z,y,x' # lambda-based (fast)
  >>> p[1].color = x,y,z # sympy expr of x,y,z
  >>> p[1].color = u,v,u*v, (u,v) # or of parameters
  


• Style property:
  >>> p[1].style = 'wireframe'
  >>> p[1].style = 'solid'
  >>> p[1].style = 'both'
  


• Natural right-click translation in the plane of the screen.
• Middle-click drag zoom.
• Progress percentage displayed in window caption for long calculations.
• z,c and numpad 1,3 rotate about the z axis regardless of camera angle.
• x and numpad 5 reset view.
