Gnu Triangulated Surface Library
- woo._gts.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 ‘body-centred’
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 side-length 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)
