# modeling-solid-model-1: Solid Model : the cutted cube

# Solid models are similar to simple models, but when they are cut by the camera front,
# plane the section is drawn, so as they appear as "solid / plain" and not "empty".

# Solid models are slower than simple model, thus you should use them only
# when the model is often cut by the camera. They are usefull for light effect, e.g.
# light cones,...


# Imports and inits Soya (see lesson basic-1.py).

# Creates a normal cube world

# Creates a cube world that will yield a solid model
# (solid models can only be used on models, NOT with faces)

# Creates a body using the normal cube
