What
is in version 3.6?
Most notably, v. 3.6 makes the
Illustrator type of splines more "Illustrator-like", in both the
way they are imported/exported and in the way they are edited in formZ;
it updates the support of SAT/ACIS import/export to version 6, which has
also improved its handling in IGES imports; it adds to OpenGL and QuickDraw
3D the ability to display open lines and to work with the extended cursor,
axis marks, snap highlights, and cross marks; it includes a number of improvements
to the Imager, ranging from general interface refinements to the ability
to generate QuickTime VR files, to directly access drafting options, such
as for the removal of duplicate lines, and to autosave images for Surface
Render, Hidden Line, Shaded Render, and RenderZone. Version 3.6 is a significant
rendering upgrade, much of which derives from LightWorks version 5.5 that
is now incorporated. Among the many rendering enhancements that v. 3.6 offers
for both RenderZone and RadioZity, the following are the most
significant:
Multiprocessor support on Windows, for Preview and Full Raytrace
modes, leading to major gains in speed. We anticipate supporting multiprocessing
on additional platforms, as they become available.
Rendering effects,
such as Exposure Correction, Depth Blur, and Background, have been enhanced,
their interface has been restructured, and are now applied through postprocessing,
which allows them to be computed independently from the main rendering
of an image. A new postprocessed effect, Lens Flares, has also
been introduced.
A variety of previously
existing shaders have been improved and new ones have been introduced.
These are Textured Brick, Wood Boards, and Solid Wood
for all types of shaders; 2D/3D Cells for Bump shaders; Woven
and Multilayer Paint for Reflection shaders.
Other quality improvements to the shaders include optiona Summation
Table Sampling that applies to all the image based shaders, and Analytic
Area Sampling for most surface (wrapped) shaders.
A new type of light,
the Line light, has been introduced. Additional overall improvements
to the lights support the ability to set transparent shadows and intensity
separately, per individual light, and improved control of the Accurate
Glow parameter for all light types.
