Does near and far paramaeter affect?

[013292]

in blender.py the near and far parameters are defined as:

# bounds, common for all scenes
        self.near = 2.0
        self.far = 6.0

What does this affect?

If I'm training on my own synthetic dataset, in what circumstances do I need to modify these two factors? Thank you :-)
