Working with Spheres

A sphere is the familiar globe-shaped polyhedron. You can control its geometric resolution, or face count (and, of course, texture it with images).
A sphere object.

To Add a Sphere:

1.   Click 3D > Geometry > Sphere to insert a Sphere node.
2.   Drag the Sphere node’s img pipe to Read node containing the clip you want to use as a texture.
3.   Drag one of the Scene node’s numbered pipes to the Sphere node to place the sphere in the scene.
4.   Use the sphere object’s transform controls to manipulate the position, scale, and rotation of the sphere in 3D space. For more information, see Transforming from the Node Properties Panel.

Adjusting Geometric Resolution

By default, a sphere has 30 rows and 30 columns. You can, however, increase or decrease either number as appropriate. For example, the figure below shows a sphere whose geometric resolution has been decreased to 2 rows and 4 columns (making it, in effect, an octahedron).

To adjust a Sphere’s geometric resolution:

1.   If necessary, double click on the Sphere node to display its parameters (and thereby select the object in the scene).
2.   Increment or decrement rows field to adjust the number of latitudinal divisions on the sphere.
3.   Increment or decrement columns field to adjust the number of longitudinal divisions on the sphere.
