Hello,
Not so long ago you have mentioned that you are working on a linear algebra library. I'm very interested in this topic, because I'm using such library in my project.
I have looked into the vault but couldn't find this library. Can we have a sneak peek?
Questions:
[SNIP]
2. will your library allow Boost.Quaternions to be extended in a way that those two libraries together will be useful for geometrical rotations?
[SNIP]
The background for question 2 above:
Author of Boost.Quaternions tried to extend the library with code that would allow geomtetrical rotations, but at that time only Boost.Ublas library was available. After some investigation he discovered that matrices and vectors from ublas are unsuitable for the task, and finally he gave up.
Following functions would be needed:
operator*(vector<3,T1>,quaternion<T2>) // most important from_rotation_matrix(matrix<3,3,T>) to_rotation_matrix() from_axis_angle(vector<3,T1> axis, T2 angle) to_axis_angle() to_euler_angles()
and few others. Similar functionality is already in boost vault: directory "Math - Numerics", file Quaternion.h
Without quaternion rotations this linear algebra library would be pretty useless for me, so I hope it'll be there :)
Paris (U.E.), le 13/07/2006 Bonjour If there is a reasonably standard (algebra, geometry) library to interface the quaternions with, I will provide the necessary functions. Speaking of the quaternion (and octonion) library, there are quite a few things which have been on my to-do list for quite some time now (like support for serialization) which I hope I will finaly have some time to work on this summer.
