General implementation of `vec<T,M>` and `mat<T,M,N>`
Presently, vec<T,M>
is only defined for M
equal to 2, 3, or 4, and mat<T,M,N>
is only defined for M
and N
equal to 2, 3, or 4. This is mainly to allow for the presence of member variables x
, y
, z
, and w
when appropriate, and to allow for construction using the {x,y,z}
syntax.
Should we also provide a general implementation of vec
and mat
which would handle sizes greater than four? These could simply use a backing array (or perhaps std::array). They would not support element access with .x
, .y
, etc., but would support access by array index, as well as all other functions and operators.
Quick comment on this. Eigen allows access via .x() -like methods to support any length. It might work for you that way.
Any update on this? I have tried myself, but it is very hard to implement properly the constructor {elms} syntax. I would love to see how this could be done for both vectors and matrices.
Yes, please add this!
This is critical functionality that I would love to have, even if the general case drops the presence of member variables x
, y
, z
, and w
or the curly brace constructor syntax.
