The computer-based creation of realistic images often requires
to generate large amount of similar objects - a mass scene.
Common modelling and rendering tools offer only the support
to copy or clone a specific object. This paper suggests an
alternative approach. By providing a parametric description
of the models, it is possible to generate many different objects
(instances) automatically. The second step is to put these objects
into the virtual scene. Different techniques for automatic object
positioning (layout) are proposed. The results are tested on the
Persistence of Vision Ray Tracer (POV-Ray) platform. To fulfil
the desired tasks, additional commands for the POV-Ray scene
description language are created.
