示例1: Scene

# 或者: from Camera.Camera import set_autocamera [as 别名]
class Scene():
def __init__(self, Particles, Camera=None):
"""
Scene class takes a sphviewer.Particles class and computes the
coordinates of the particles as seen from a Camera. It is to say,
for a given particle, whose coordinates are x,y and z, Scene
computes a new set of coordinates x' and y', which are the aparent
coordinates of the particles as seen from a camera.
By default, Camera=None means that Scene have to use an autocamera. It
will try to define a Camera whose parameters have some sence according
to your data set. In case you want to prevent Scene from using an autocamera,
you should provide a valid Camera Class.
As Particles class, Scene has its own getting and setting methods.
setting methods:
----------------
- set_autocamera
- update_camera
getting methods:
----------------
- get_scene
- get_extent
other methods are:
- plot

uses a density criterion for getting the point of view. If this is
not a good option for your problem, you can choose among:

an array that contains the extreme values of the scene.
