pytracer's Issues

Implement Bounded Volume Heirarchy

Lixel intercept testing would be much faster if a Bounded Volume Heirarchy was implemented.

Instead of looping over all lixels in geometry mesh, create a BVH in Geometry.flattten() routine, and then call something like geometry.find_intercept_lixels(start, end) which returns intercepting lixels using BVH.

Not sure if there is a lower limit where BVH is slower than brute force

Add unit tests

Use https://docs.python.org/2/library/unittest.html#
PTVS can also support unit tests

Add Documentation

Most classes, methods, functions do not have any docstrings for documentation.
PEP 0257 describes the standard format

Single line

def kos_root():
    """Return the pathname of the KOS root directory."""

Multi-Line

def complex(real=0.0, imag=0.0):
    """Form a complex number.

    Keyword arguments:
    real -- the real part (default 0.0)
    imag -- the imaginary part (default 0.0)
    """
    if imag == 0.0 and real == 0.0:
        return complex_zero
