Create a superquadric according to the theta and phi roundness parameters. This one source can generate a wide variety of 3D objects including a box, a sphere, or a torus.
The Superquadric source can be used to add a polygonal superquadric to the 3D scene. This source can be used to create a wide variety of shapes (e.g., a sphere, a box, or a torus) by adjusting the roundness parameters. The output of the Superquadric source is polygonal data with point normals and texture coordinates defined.
Property  Description  Default Value(s)  Restrictions 
Center (Center) 
This property specifies the 3D coordinates of the center of the superquadric. 
0 0 0  
Phi Resolution (PhiResolution) 
The value of this property represents the number of divisions in the phi (latitudinal) direction. This number will be rounded to the nearest multiple of 4. 
16 
The value must be greater than or equal to 4 and less than or equal to 1024.

Phi Roundness (PhiRoundness) 
This property defines the roundness in the phi (latitudinal) direction. A value of 0 represents a rectangular shape, a value of 1 represents a circular shape, and values greater than 1 produce higher order shapes. 
1 
The value must be greater than or equal to 0.01.

Scale (Scale) 
The three values in this property are used to scale the superquadric in X, Y, and Z. The surface normals will be computed correctly even with anisotropic scaling. 
1 1 1  
Size (Size) 
The value of this property represents the isotropic size of the superquadric. Note that both the Size and Thickness properties control coefficients of superquadric generation, so the value of this property may not exactly describe the size of the superquadric. 
0.5  
Theta Resolution (ThetaResolution) 
The value of this property represents the number of divisions in the theta (longitudinal) direction. This value will be rounded to the nearest multiple of 8. 
16 
The value must be greater than or equal to 8 and less than or equal to 1024.

Theta Roundness (ThetaRoundness) 
This property defines the roundness of the superquadric in the theta (longitudinal) direction. A value of 0 represents a rectangular shape, a value of 1 represents a circular shape, and values greater than 1 produce higher order shapes. 
1 
The value must be greater than or equal to 0.01.

Thickness (Thickness) 
If the value of the Toroidal property is 1, this value represents the thickness of the superquadric as a value between 0 and 1. A value close to 0 leads to a thin object with a large hole, and a value near 1 leads to a thick object with a very small hole. Changing the thickness does not change the outer radius of the superquadric. 
0.3333 
The value must be greater than or equal to 0.0001 and less than or equal to 1.

Toroidal (Toroidal) 
If the value of this property is 0, the generated superquadric will not contain a hole (i.e., the superquadric will be ellipsoidal). Otherwise, a toroidal object is generated. 
1 
Only the values 0 and 1 are accepted.

Only the values 0 and 1 are accepted.

X Amplitude (X Amplitude)

Y Amplitude (Y Amplitude) 
Controls how far the data set moves along Y over time.

Wavelet
Create a regular rectilinear grid in up to three dimensions with values varying according to a periodic function.
The Wavelet source can be used to create a uniform rectilinear grid in up to three dimensions with values varying according to the following periodic function.
OS = M * G * (XM * sin(XF * x) + YM * sin(YF * y) + ZM * cos(ZF * z))
OS is the output scalar; M represents the maximum value; G represents the Gaussian; XM, YM, and ZM are the X, Y, and Z magnitude values; and XF, YF, and ZF are the X, Y, and Z frequency values. If a twodimensional extent is specified, the resulting image will be displayed. If a threedimensional extent is used, then the bounding box of the volume will be displayed.

Center (Center)

Maximum (Maximum) 
This parameter specifies the maximum value (M) of the function.

Standard Deviation (StandardDeviation) 
This property specifies the standard deviation of the Gaussian used in computing this function. 
0.5  
Subsample Rate (SubsampleRate) 
This property specifies the rate at which to subsample the volume. The extent of the dataset in each dimension will be divided by this value. (See the Whole Extent property.) 
1 
The value must be greater than or equal to 1.

Whole Extent (WholeExtent) 
The six values in this property indicate the X, Y, and Z extent of the output data. The first two values represent the minimum and maximum X indices, the next two are the minimum and maximum Y indices, and the last two are the minimum and maximum Z indices.
