The Sphere SOP generates spherical objects of different geometry types. It is capable of creating non-uniform scalable spheres of all geometry types.
If an input is provided, the sphere's radius is automatically determined as a function of the input's bounding geometry.
Parameters - Page
type - ⊞ - Select from the following types. For information on the different types, see the Geometry category articles. Depending on the primitive type chosen, some SOP options may not apply.
surftype - ⊞ - This option is used to select the type of surface, when using a Mesh Primitive Type.
rows- Creates horizontal lines.
cols- Creates vertical lines.
- Rows and Columns
rowcol- Both Rows and Columns. Looks like Quads in wire frame display, but all polygons are open (if the primitive type is polygon).
triangles- Build the grid with Triangles.
quads- Generates sides composed of quadrilaterals (default).
- Alternating Triangles
alttriangles- Generates triangles that are opposed; similar to the Triangles option.
orientbounds - Available only when an input is connected to the Sphere SOP to set bounds for the sphere. When Orient Bounds = On it will rotate the geometry to match the orientation of the input SOP used for bounds.
modifybounds - Available only when an input is connected to the Sphere SOP to set bounds for the sphere. When Modify Bounds = On the transform parameters below will further modify the rotation, position, and radius of the bounds.
rad - ⊞ - The radius of the sphere in X, Y and Z.
t - ⊞ - Offset of sphere center from object center.
orient - ⊞ - Determines axis for sphere. Poles of sphere align with orientation axis.
- X Axis
- Y Axis
- Z Axis
freq - This controls the level of polygons used to create the sphere, when using the Polygon Primitive Type.
rows - Number of rows in a sphere when using the mesh, imperfect NURBS and imperfect Bzier.
cols - Number of columns in a sphere when using the mesh, imperfect NURBS and imperfect Bzier.
orderu - If a spline curve is selected, it is built at this order for U.
orderv - If a spline curve is selected, it is built at this order for V.
imperfect - This option applies only to Bzier and NURBS spheres. If selected, the spheres are approximated nonrational curves, otherwise they are perfect rational curves.
Unique Points per Pole
upole - Applies to Mesh, NURBS and Bzier surfaces only. This option determines whether points at the poles are shared or are individual to the columns.
accurate - If the SOP is being used to generate a bounding sphere for it's input geometry, this parameter tells the SOP to use a more accurate (but slower) bounding sphere calculation.
texture - ⊞ - Adds UV texture coordinates to the sphere.
off- No UV coordinates added to surface.
- By Primitive Type
byprimtype- Adds vertex UV coordinates.
- Equirectangular Inside (Spherical Polar)
- Equirectangular Outside (Spherical Polar)
- Equidistant Azimuth (Fish Eye 180)
- Equidistant Azimuth (Fish Eye 360)
normals - Creates normals on the geometry.
- Input 0 -
