· boost/la/all.hpp conflicts with boost/assign/list_of.hpp if Boost.Assign is included first. I think this has to do with missing includes in a few headers.
What do you mean missing includes? All (Boost) LA headers compile on their own (this is explicitly tested in the libs/la/test/Jamfile.)
· Expressions like rotx_matrix() * roty_matrix() don't work. The temporaries have to be stored in proper matrix variables first. Apparently its result type does not model a valid matrix? (just guessing).
Do you have code that demonstrates the problem? Which compiler? The following works for me: #include <boost/la/all.hpp> int main() { using namespace boost::la; rotx_matrix<3>(0.0f)*roty_matrix<3>(0.0f); //returns mat<float,3,3> } What doesn't work is rotx_matrix<D>()*rotx_matrix<D>(), but I'm not sure if that's a big problem.
· Could we have translation_matrix and scale_matrix, just as we have rot*_matrix ?
If v is an object of a vector type, v|trans_matrix will give you a translation matrix of size D+1, where D is the size of v's type. Similarly, v|diag_matrix will give you a scaling matrix.
· There is no (vector) normalize function. The implementation is straightforward.
I don't know how I've missed that. Will do.
· During RangeEx review, the use of views and algorithms was widely discussed. It would be good for Boost.LA to follow the same conventions decided back then. IIRC, `m | transposed` was a lazy view and `transpose(m)` returned a new (eagerly) modified value. I should go back to the archives to confirm this was indeed the conclusion.
I'm not sure I understand your point, or maybe you need a different example. In (Boost) LA, m|transpose returns a transposed mutable reference to m.
· I would like to have X, Y, Z and W placeholders be convertible to the axis versor. However I don't think this can be actually implemented. Maybe something like versor<float,3>( X ) or unit_vector<float,3>( X ) would be better.
Could you provide an example of what you want exactly? Emil Dotchevski Reverge Studios, Inc. http://www.revergestudios.com/reblog/index.php?n=ReCode
