Hi Bryan and Casba,

First of all I would want to confess that I have no experience in handling
issues where different types of languages talking to each other and have a
luxury to share data. But I wish to learn. And your help is solicited.

I am trying to implement the VOL primitive.

Now I have following doubts regarding implementing :

rt_vol_internal has matp_t mat : I saw that matp_t is supposed to contain
4X4 matrix of double type. I didnt find a corresponding implementation in
ctypes_adaptors, should I use points in this case with pointsize = 4x4 = 16.

This contains 5 size_t data points (xdim, ydim, zdim, lo, hi) all of which
are part of the struct and also required in the function mk_vol.

Although the cellsize can be represented as direction from ctypes_adaptors.

Rest are simple.

Please guide me regarding the implementation details. Also if you can point
me to some part of code (which i am missing), or any literature that will
be helpful.

With Best,

Raj.
