Asset Examples

-- Model Distance
-- Creates a screen space window into which 3D model of the Eiffel tower is rendered. As
-- the objects are rendered in meter scale, and the Eiffel tower is about 300m tall, we
-- place the camera at a great distance to be able to see the entire Eiffel tower at the
-- same time.

-- Download the model file for the Eiffel tower
