Hi

Great you like gl3n. For a projection-matrix use: mat4.perspective or if 
you want an orthographic: mat4.orthographic, unfortunatly ddoc ignores 
this block (I think because of "static if(isFloatingPoint!mt)", it 
begins here: 
https://bitbucket.org/dav1d/gl3n/src/affe3816c7a4/gl3n/linalg.d#cl-1080

I don't know VisualD but you've normally to add the path to the files 
(base dir, it is -Ipath/goes/here for dmd) and also each file, it could 
look like this:

-Igl3n/ gl3n/interpolate.d gl3n/linalg.d gl3n/math.d gl3n/util.d my_prog.d

and in my_prog.d you import the parts of gl3n as follows:

import gl3n.linalg; // if you want linear algebra, vectors, matrices and 
quats
import gl3n.math; // if you need math, normally you always do!
import gl3n.interpolate; // for interpolation functions
import gl3n.util; // to check for types

Hope this helps
