The easiest way to do that is using the viewer tool:

  viewer.py my_scene.3ds

This will load the file and visualize it using OpenGL.

from cgkit.all import *
load("my_model.3ds")
model = worldObject("model_name")
model.geom.intersectRay((1,2,3), (0,1,0))

You can find out the name of your geometry by calling listWorld() after 
loading the model which will dump the names of the objects in the 
current scene.
If you do all that from within a script that is invoked using the viewer 
tool you could omit the first two lines (i.e. the import and load()) and 
pass the file name on the command line.

The load(), worldObject() and listWorld() functions are mentioned here:
