| form·Z RenderZone is the version of
form·Z that includes photorealistic rendering based on
the LightWorks® rendering engine.
It offers seven levels of rendering: flat, Gouraud, Phong,
preview z-buffer, full z-buffer, preview raytrace, and full
raytrace.
One or more lights can be used, which can be distant (sun),
cone, point, or projector lights. Any of these lights may
appear to glow in images, and they are in addition to the
globally available ambient light.
Both soft (bit-mapped) and hard (raytraced) shadows are produced
by all the levels above Phong.
Both procedural and pre-captured textures are offered and
can be mapped onto the surfaces of objects using five different
mapping methods: flat, cubic, cylindrical, spherical, or parametric,
which applies to NURBS surfaces. A preview environment offers
easy methods for both positioning and viewing textures as
they are mapped onto objects.
Cubic and spherical environment mapping, bumps, backgrounds
that include alpha channel support, and depth effects can
be applied starting with the preview z-buffer level. Blur
is an example of a depth effect that simulates focusing your
camera to a particular area of your modeling scene. Sky backgrounds
that are procedurally generated come close to real skies that
you may have captured with your camera.
Transparencies, reflections, and refractions can be applied
at the full z-buffer and the full raytrace levels. The reflections
and refractions are always correctly raytraced, even when
they are produced by the z-buffer rendering. This is achieved
by applying a mixed rendering method, where surfaces with
no reflections are rendered using z-buffer, and the rendering
effects of reflective surfaces are produced using raytracing.
State of the art shaders are used to render surfaces and
other effects. A surface style is defined by up to four layers
of shaders, which produce color, reflections, transparency,
and bump effects. They can be applied independently or can
be correlated. For example, the same procedural or precaptured
texture can be used for the color, and then also as a transparency
filter or bump mask. Surface styles can be assigned to complete
objects, or to groups of faces called texture groups.
Decals can be attached on top of other surface styles to
produce a variety of rendering effects, such as labels on
objects, graffiti on walls, partially reflective surfaces,
masked transparencies, and more. Up to thirty-two decals can
be applied to a single object, and because these decals may
freely overlap, the rendering effects can be combined in virtually
unlimited ways.
Mixed wire frame and shaded renderings can be produced in
the same image, in both form•Z and RenderZone. The wire
frames can even cast shadows.
Natural looking trees, which have been precaptured, can be
included in renderings with particular ease.
Libraries with predefined materials are included and can
be easily extended and customized by users.
Images can be rendered and saved in a variety of user controlled
sizes and resolutions, to a maximum of 16,000 x 16,000 pixels.
Partially rendered images can also be produced and saved.
The Imager, a utility which is incorporated in the program
and is also available independently, can be used to batch
render sequences of images whose viewing and rendering parameters
are previously set and saved.
