This is useful when using objects that were imported through 3DSIN, or when
using PFACE objects. When you select this option, all objects in the drawing
are made smooth. If you don’t want all objects to be smooth, recreate the
model using a different object type.
Transparency Quality
Adjusts the transparency quality used when viewing or rendering a model.
The transparency quality used is dependent on if software or hardware
acceleration are used, or if a model is being rendered. The default quality is
Medium.
Software acceleration
■ Low quality produces a screen-door effect to achieve transparency without
sacrificing speed.
■ Medium quality uses a combination of the screen-door effect and alpha
blending.
■ High quality uses simple alpha blending, which can cause graphical artifacts
to appear based on the current draw order.
Hardware acceleration
■ Low quality uses simple alpha blending, which can cause graphical artifacts
to appear based on the current draw order.
■ Medium quality uses a two-pass algorithm to draw all opaque objects,
followed by all transparent objects. The transparent objects are drawn
using simple alpha blending, which can cause graphical artifacts to appear
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.
