For use MagicaVoxel as a render for Moi3D! :)
As Moi don't yet manage the VOX format...
https://github.com/ephtracy/voxel-model/blob/master/MagicaVoxel-file-format-vox.txt
there are some tricks !
First Thanks Stefan : Just Drag and Drop your Moi's file saved in OBJ format inside the "active matrix" (empty or full) on the Magica's Screen!)
It will be remplaced by your object!
But there is a limitations of the "direct" Matrix : maximum is 126 * 126 * 126 cubes!
If you want more little cubes for have more precision you need more than one matrix of 126*126*126 !
So in this case where the object is not too complex and no need ultra precision that works fine with one matrix existing on the screen! :)

From an internal view...
Here each cubes i a Sphere!

Of course Magica can manage several Matrix of 126 ;)
In theory 16*16*16 (4 096) matrix of 126*126*126 (so 2 000 376 Voxels (cubes) but not sure that the render takes all of them!)
If you want a more defined "cubic object" from your Moi's Object you must trim it in several parts before Drag & Drop them
with some other little tricks! ;)
I will make a tutorial soon for that!
For the moment a simple Moi Object

Imported by Drag& Drop and copy the Magica Matrix
Use the "Stereographic Projection" of the render with Grid and Edge rendering enable!
You can give Colors to the Edge and Grid!!! (here red edges & Gray grid)
BackGround is Blue, Ground is Yellow or any color you want...
And of course some different material that you want for the object's faces themselves!
Here just Glass Material!
You can explore in real time trough the objects like inside a sort of 3D univers depending of the Angle of the Stereographic Projection!
Best is taken 150° to 270° for have a some deformed view! ;)
can be resulting somewhere
other one
Playing with the Voxel xyz function of the render!
Tuto for split a Moi object in several acceptable Magica matrix...soon...
