To add a spherical grid, the following data are required:
-- the center (vertex) of the central hexahedron: *pt*
-- the vector corresponding to the diametrically opposite vertex to the
- initial vertex: *dv*
+- the center (vertex) of the central hexahedron: *c*
+- the radius of the internal hexahedron: *r*
- the number of embedded hexahedra: *n*
- the coefficient of growth:*k*
Make a spherical grid::
- elts = doc.makeSpherical(pt, dv, n, k)
+ elts = doc.makeSpherical(c, r, n, k)
+
+Operations on *elts*: :ref:`tuielements2`
+
The result is an array of hexahedra starting with the central and
other hexahedral are arranged layer by layer from the center. Each
Example
-------
-::
-
- import hexablock
- doc = hexablock.addDocument()
-
- orig = doc.addVertex(0, 0, 0)
-
- direction = doc.addVector(1, 1, 1)
-
- dx = doc.addVector(1, 0, 0)
- dy = doc.addVector(0, 1, 0)
- dz = doc.addVector(0, 0, 1)
-
- n = 2
- k = 0.8
-
- grid = doc.makeSpherical(orig, direction, n, k)
