NOTE In wireframe display mode, if you select Display > NURBS > Fine or
Medium, more isoparms appear than there are actual spans and sections.
The surface is visually displayed with extra precision, but the extra isoparms
have no CVs and cannot be edited.
3 Name the sphere Egghead.
4 Rotate the sphere 90 degrees on its side (Rotate Z: 90). This positions the
spheres CVs well for modeling a simple head and face. Youll learn why
later in this lesson.
5 To give Egghead an oval shape, set the ScaleX for the sphere to 1.3 or so.
Optionally, you can move Egghead above the grid so the grid doesnt
interfere with your view of Egghead. Also, position the perspective view
so the Z-axis of the View Axis points toward you.
Modifying the surface material for easier viewing
Because you will do subtle surface modeling in this lesson, its helpful to
display Egghead with bright highlights so you can clearly see the effects of
the changes you make. In the next steps, youll assign a Blinn material to
Egghead to give its surface bright highlights. The steps have no explanations,
as the shading subject matter is the focus of a later lesson.
To assign a Blinn surface material
1 With Egghead selected, press 5 to display the surface with smooth shading.
2 Right-click Egghead and select Assign New Material > Blinn.
The Attribute Editor will immediately be displayed for the Blinn material.
3 Drag the Color attribute slider roughly 3/4 of the way to the right, set
Eccentricity to 0, and close the window.
