Sphere SOP
Summary[edit]
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
Primitive Type 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.
- Primitive
prim-
- Polygon
poly-
- Mesh
mesh-
- NURBS
nurbs-
- Bezier
bezier-
Connectivity surftype - ⊞ - This option is used to select the type of surface, when using a Mesh Primitive Type.
- Rows
rows- Creates horizontal lines.
- Columns
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
triangles- Build the grid with Triangles.
- Quadrilaterals
quads- Generates sides composed of quadrilaterals (default).
- Alternating Triangles
alttriangles- Generates triangles that are opposed; similar to the Triangles option.
Orient Bounds 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.
Modify 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.
Radius rad - ⊞ - The radius of the sphere in X, Y and Z.
- X
radx-
- Y
rady-
- Z
radz-
Center t - ⊞ - Offset of sphere center from object center.
- X
tx-
- Y
ty-
- Z
tz-
Orientation orient - ⊞ - Determines axis for sphere. Poles of sphere align with orientation axis.
- X Axis
x-
- Y Axis
y-
- Z Axis
z-
Frequency freq - This controls the level of polygons used to create the sphere, when using the Polygon Primitive Type.
Rows rows - Number of rows in a sphere when using the mesh, imperfect NURBS and imperfect Bzier.
Columns cols - Number of columns in a sphere when using the mesh, imperfect NURBS and imperfect Bzier.
U Order orderu - If a spline curve is selected, it is built at this order for U.
V Order orderv - If a spline curve is selected, it is built at this order for V.
Imperfect 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 Bounds 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 Coordinates texture - ⊞ - Adds UV texture coordinates to the sphere.
- Off
off- No UV coordinates added to surface.
- By Primitive Type
byprimtype- Adds vertex UV coordinates.
- Equirectangular Inside (Spherical Polar)
equirectangularin-
- Equirectangular Outside (Spherical Polar)
equirectangularout-
- Equidistant Azimuth (Fish Eye 180)
equiazimuth-
- Equidistant Azimuth (Fish Eye 360)

Compute Normals normals - Creates normals on the geometry.
