Extrude Box Mesh by Face

[hen]

Im wondering if its possible to extrude a box mesh by face.

Like to create a dynamic cube wich could be extruded in to all 6 directions at runtime?

I don't really get what you mean ...

Sound like he want to scale the cube but by faces, not the entire axis like the scale function do.

it would be more like box.rightFace.scale = 2.0;

 

of course meaning you have : topFace, bottomFace, leftFace, rightFace, nearFace and farFace.

Yes, thats basicly what i want to do...

 

Im thinking about to do this by moving the face vertices in to the extrude direction but im actually struggling to select vertices connected to the boarders of a picked face.

something you could do maybe with updateMeshPositions() : http://doc.babylonjs.com/tutorials/How_to_dynamically_morph_a_mesh#other-shapes-updatemeshpositions

Just keep in mind that each box face is 4 successives vertices (so 12 position elements) in the positions array
