PyTAPS 1.4

Installation
PyTAPS requires the following to be installed on your system:

Python 2.5+
NumPy 1.3.0+
At least one of…

MOAB (or other iMesh
interface)
CGM (or other iGeom
interface)
Lasso (or other iRel
interface)

Once you have the prerequisites, the easiest way to install PyTAPS is to use
Pip (0.7+ recommended):
pip install pytaps
This will download, compile, and install PyTAPS automatically. If you have some
but not all of the ITAPS interfaces (e.g. only iMesh), this will only install
interfaces for the libraries you have, as described in Autodetection of
Libraries.

Building Manually
Like many Python packages, PyTAPS uses Setuptools for installation, so in
general setup consists simply of downloading the tarball, extracting it, and
typing python setup.py install inside the extracted directory. However,
certain ITAPS interfaces may require some additional setup.

Autodetection of Libraries
The PyTAPS setup script supports importing definitions from the
iXxx-Defs.inc files, where iXxx is the name of the interface. PyTAPS will
attempt to find these files automatically, by searching in some common
locations:

The files specified in the environment variables IXXX_DEFS
For each directory dir in the environment variables PATH and
CPATH, look in dir/../lib
Each directory in the environment variable LD_LIBRARY_PATH
/usr/local/lib
/usr/lib

If the PyTAPS setup script cannot find the iXxx-Defs.inc file, it will
assume you do not have that interface installed and automatically disable it in
PyTAPS.
If you have the iXxx-Defs.inc files installed but not in any of the above
locations, you can specify where they are in the global command-line options
--iXxx-path=PATH, like so:
python setup.py --iMesh-path=PATH install

Usage
The following example illustrates the basics of using iMesh. This script gets
all the faces of a mesh and prints out the coordinates of their vertices:
from itaps import iBase, iMesh

mesh = iMesh.Mesh()
mesh.load("mesh.vtk")

faces = mesh.getEntities()
adj = mesh.getEntAdj(faces, iBase.Type.vertex)

for i in adj:
for j in i:
x, y, z = mesh.getVtxCoords(j)
print "%f, %f, %f" % (x, y, z)
print

Testing
Basic tests of the interfaces are located in test/. To run all the tests, run
python setup.py test. To run a subset of tests, use -S <suite_name>,
e.g. python setup.py -S test.imesh.
