vtkSuperquadricSource creates a superquadric (represented by polygons) of specified size centered at the origin. The resolution (polygonal discretization) in both the latitude (phi) and longitude (theta) directions can be specified. Roundness parameters (PhiRoundness and ThetaRoundness) control the shape of the superquadric. The Toroidal boolean controls whether a toroidal superquadric is produced. If so, the Thickness parameter controls the thickness of the toroid: 0 is the thinnest allowable toroid, and 1 has a minimum sized hole. The Scale parameters allow the superquadric to be scaled in x, y, and z (normal vectors are correctly generated in any case). The Size parameter controls size of the superquadric.
This code is based on "Rigid physically based superquadrics", A. H. Barr, in "Graphics Gems III", David Kirk, ed., Academic Press, 1992.
-
Warning:
-
Resolution means the number of latitude or longitude lines for a complete superquadric. The resolution parameters are rounded to the nearest 4 in phi and 8 in theta.
-
Warning:
-
Texture coordinates are not equally distributed around all superquadrics.
-
Warning:
-
The Size and Thickness parameters control coefficients of superquadric generation, and may do not exactly describe the size of the superquadric.
