isosurface
()¶ Adds to surface new faces defining the isosurface data[x,y,z] = c
Signature: isosurface(data, c, …)
data is a 3D numpy array. c is the isovalue defining the surface
Keyword arguments: extents= [xmin, xmax, ymin, ymax, zmin, zmax]
A numpy array defining the extent of the data cube. Default is the cube with corners at (1,1,1) and (1,1,1) Data is assumed to be regularly sampled in the cube. method= [‘cube’’tetra’’dual’’bounded’]
String (only the first character counts) specifying the method. cube – marching cubes (default) tetra – marching tetrahedra dual – maching tetrahedra producing dual ‘bodycentred’
faces relative to ‘tetra’ bounded – marching tetrahedra ensuring the surface is
 bounded by adding a border of large negative values around the domain.
By convention, the normals to the surface are pointing towards positive values of data[x,y,z]  c.

woo._gts.
merge
()¶ Merges list of Vertices that are within a box of sidelength epsilon of each other.
Signature: merge(list,epsilon)

woo._gts.
read
()¶ Returns the data read from File f as a Surface. The File data must be in GTS format (e.g., as written using Surface.write())
Signature: read(f)

woo._gts.
segments
()¶ Returns tuple of Segments from a list or tuple of Vertices.
Signature: segments(list)

woo._gts.
sphere
()¶ Returns a unit sphere generated by recursive subdivision. First approximation is an isocahedron; each level of refinement (geodesation_order) increases the number of triangles by a factor of 4.
Signature: sphere(geodesation_order)

woo._gts.
triangle_enclosing
()¶ Returns a Triangle that encloses the plane projection of a list or tuple of Points. The Triangle is equilateral and encloses a rectangle defined by the maximum and minimum x and y coordinates of the points.
Signature: triangles(list)

woo._gts.
triangles
()¶ Returns tuple of Triangles from a list or tuple of Edges.
Signature: triangles(list)

woo._gts.
vertices
()¶ Returns tuple of Vertices from a list or tuple of Segments.
Signature: vertices(list)
