      This paper describes the design of GeoPrO: a distributed
      programming environment for geometric visualization.  We present
      an overview of its classes that allow for easy extensibility and
      portability.  Due to a client-server architecture, comprised of
      a kernel, with multiple contexts, applications and visualizers,
      GeoPrO supports distributed execution over a heterogeneous
      network.  Visualizers are currently available for the planar and
      the spheric models of the oriented projective geometry, running
      on SGI workstations, while another is being implemented in Java
      for multi-platform support.
