Compass
Draws a 3D sphere within the arcball composed of three lines representing
the X, Y, and Z axes.
Continuous Orbit
Changes the cursor to a sphere with two continuous lines encircling it and
enables you to set the objects into continuous motion. See 3DCORBIT.
Flat Shaded
Shades the objects in the 3D Orbit view between the polygon faces. This
gives the objects a faceted, less smooth appearance.
Flat Shaded, Edges On
Combines the Flat Shaded and Wireframe options. The objects are flat
shaded with the wireframe showing.
Front Clipping On
Turns the front clipping plane on or off. A check mark in front of this option
indicates that the front clipping plane is on and you can see the results of
moving the line that adjusts the front clipping plane. See 3DCLIP.
Gouraud Shaded
Shades the objects in the 3D Orbit view and smooths the edges between
polygon faces. This gives the objects a smoother, more realistic appearance.
Gouraud Shaded, Edges On
Combines the Gouraud Shaded and Wireframe options. The objects are
Gouraud Shaded with the wireframe showing.
Grid
Displays a two-dimensional array of lines similar to graph paper. This grid
is oriented along the X and Y axes.
Before starting 3DORBIT, you can use the GRID command to set system
variables that control the grid display. The number of major grid lines
corresponds to the value you set using the Grid Spacing option of the GRID
command, which is stored in the GRIDUNIT system variable. Ten horizontal
lines and ten vertical lines are drawn between the major lines.
Hidden
Displays the objects in the 3D Orbit view as wireframes with the lines
representing the back faces hidden.
