based on the current draw order. The graphical artifacts are less noticeable
due to the opaque objects being drawn prior to the transparent objects.
■ High quality improves on medium quality by sorting transparent objects
to decrease the appearance of graphical artifacts. However, the sorting does
not completely eliminate all graphical artifacts.
Rendering
■ Low quality disables the use of transparency for all materials, and the
materials are rendered as opaque instead.
■ Medium quality enables transparency for materials, but the actual material
opacity used is the square root of the specified material opacity.
■ High quality enables transparency and the opacity assigned to a material
is mapped directly to Mental Ray rendering engine.
Drawing Settings
Sets performance values on a drawing level.
Dynamic Tessellation
Sets the options that determine the smoothness of the objects in a drawing.
Objects are drawn using many short lines (or triangles when drawing spheres).
These lines are called tessellation lines. Objects in your drawing appear smoother
when you use more tessellation lines.
Surfaces
Determines the amount of detail for surfaces in your drawing. The low end
of the slider provides fewer tessellation lines and uses less memory.
Curves
Determines the amount of detail for curves in your drawing. The low end of
the slider provides fewer tessellation lines and uses less memory.
Number of Tessellations to Cache
Configures your system according to memory and performance requirements.
The 3D cache always stores at least one tessellation. When this option is set
to 1, the tessellation for all viewports is the same; some objects in the drawing
may be regenerated as you zoom in and out. Setting this option to 2 or more
is useful when you have more than one viewport with different views.
Increasing the number requires more memory.
