A Body Object is defined
procedurally, and so must be converted to a mesh object for displaying
in the viewport. These controls determine how the software performs
this conversion. You can specify a different conversion method for
rendering or use the Viewport Display settings.
- Display Options
Choose how the Body Object
displays in the viewports:
only the isoparametric curves in both shaded and wireframe viewports.
only the polygons for both shaded and wireframe viewports.
the mesh in shaded viewports and edges and isoparametric curves
in wireframe viewports. If you activate the Edged Faces option in
a shaded viewport you can also see the curves in this mode.
Four different display
modes in shaded viewport:
1. Mesh (or Both) display
with Edged Faces off
2. Curves display
3. Mesh display with
Edged Faces on (Coarse mesh quality preset)
4. Both display with
Edged Faces on
- Mesh Quality Presets
Choose an overall setting that
automatically determines the remainder of the Viewport Display settings. The
default choice, Coarse, provides adequate viewport rendering quality
with maximum speed of interaction.
mesh generation; generates the fewest polygons.
mesh generation; generates the largest number of polygons.
Mesh Display group
The Mesh Display settings
control how the Body Object is displayed in the viewport. These
settings are also used when converting to editable mesh/poly format
to control how the polygons are created.
Smoothes out polygons, removing
tiny edges and polygons.
This option welds vertices
and uses smoothing groups instead of the natural surface normals.
This is useful primarily when preparing the viewport mesh for conversion
to an editable mesh where welding is needed. If you don't use this
option, duplicate vertices will result between some of the faces
of the output mesh corresponding to the edge boundaries between
faces of the body object.
- Face Approx Angle
The maximum angle for each
pair of polygon faces. Faces with an angle greater than this value
between them are subdivided into multiple polygons. Decreasing this
value increases the mesh resolution.
- Edge Approx Angle
Similar to Face Approx Angle,
but defines the maximum angle for a polygon edge. The default value
of 0.0 disables this setting.
- Face Distance %
The maximum allowable absolute
error between the mesh and the actual precise (solid) geometry.
The percentage is based on the size of the object. Adjusting this
value is the preferable way to increase the mesh quality without
getting too many polygons.
- Edge Distance %
Similar to Face Distance %,
but defines the maximum allowable error for polygon edges. The default
value of 0.0 disables this setting.
- Max Edge Len. %
The maximum length for any
mesh edge. Adjust this setting to get a mesh without long, narrow
polygons. This value is used to control the subdivision
of the display mesh. The default value of 0.0 disables
TipWhen using a modifier
to deform the Body Mesh, set Max Edge Len. % to 2.0 or 3.0 to obtain
Bent hair dryer with
Max Edge Len. %=0.0 (the default)
Bent hair dryer with
Max Edge Len. %=3.0; smaller polygons yield smoother deformation.
- Smoothing Passes
The number of passes during
the smoothing step. Increasing this value can help improve the shape
of very narrow triangles.
Curve Display group
- Lines U/V
The number of crosshatch
curves for isoparametric curve display; the number of subdivisions
in the U or V direction.
The additional curves
produced by settings above 0 (the default) are for display purposes
only, and have no effect on the geometry. For an illustration, see
- Display Surface Knots
Displays isoparametric curves
at the NURBS knots on the faces.
- Approx Angle
The angle tolerance to use
in the display of isoparametric curves. For finer curves, use lower
values. For a circle, if you set this to 10, you get 36 or more segments.
TipThis is the primary
setting for controlling the quality of the curve display, and will suffice
in most situations. For shallow curves, try using Curve Distance
% (see following) as well.
- Curve Distance %
The chord height used
to display isoparametric curves. For finer curves, use lower values.
For example, setting this to 1% with a high Angle Tolerance value
gives you about 16 segments on a circle.
TipThis setting is most
useful with shallow curves, such as a car hood, where the whole
angle across the curve is only a few degrees.
