Re: lots of problems VC7.1

Cheers.

This is not an attempt to analyze the info.

Please don't treat my answer as criticism , but only a
few remarks based on personal expierience.(not
objective opinion!)

If you see any errors , placed in files of mtl,
like light1D.h or so ,
generally it is your fault, somewhere.
Check the origin of the error, when occurs, when not.

That is it , but if you wish more here it is :

More :

Initially I was writing every class as follows :

newclass.h -> declaration,
newclass_impl.h -> implementation of templated
functions, dependent on various matrices.

But as code grows (computational math as yours), there
sometimes really tough errors occur.

After being tired after one of such bugs,
I hanged my strategy into conventional one.
(newclass.h and newclass.cpp)

I use not templated classes, (or rather decrease their
number as much as possible) 
though being able to use all funcionality of MSVC,
treating MTL as highly flexible tool.

Keep all clear and maintain functionality of MSVC.

...
also it would be perfect to use with Intel compiler,
if possible.
