form Z Renderzone

form·Z RenderZone Plus is the version of form·Z that,
in addition to all the modeling/drafting/animation tools found
in the basic package (described here), includes photorealistic
rendering based on the LightWorks® rendering engine. It offers  three levels of rendering: simple, z-buffer, and raytrace.
A user can start developing the image of a 3D model at the
simple level and gradually turn on features and render it at
the most photorealistic level.

form•Z RenderZone Plus also includes the ability to produce images
based on global illumination techniques, which create renderings with
the most realism, as the illumination of a scene takes into account the
accurate distribution of light in the environment. In RenderZone Plus,
global illumination includes final gather, ambient occlusion,
and radiosity techniques, which can be applied separately or can be combined.

One or more lights can be used, which can be distant (sun), cone, point,
projector, area, custom, line, environment, and atmospheric lights.
Any of these lights may appear to glow in images and they are in
addition to the globally available ambient light. The environment
and atmospheric lights, which may be considered advanced light types,
are especially optimized for global illumination.
