How to simulate "Projection Camera Mapping" of video on to a Babylon Mesh?

How would I project a standard 16:9 video onto multiple  Babylon mesh (live code) (sample meshs in pink bg, teal lines, gray sphere image below); as if, the camera was a projector and the mesh was an object in a space ?

The results I'm looking for is that the video would serve more as a gradient of colors to the mesh or on the otherhand a distortion to the video itself. 

 

Hope this makes sense, I've attached an image from cinema 4d on the concept I'm taking about.

@Deltakosh Thats exactly what I was looking for with a few exceptions, Sample code: http://www.babylonjs-playground.com/#203BJM#5

1. Is it possible to apply it to the BABYLON.Mesh.CreateLines()? if not, any ideas on how you would approach creating a crazy mesh like I have below with a different type of geometry?

 

    for (var u = 0; u <= 2*Math.PI; u += incrementer){
        for( var v = 0; v <= 2*Math.PI; v += incrementer){

            points.push(new BABYLON.Vector3(
                    Math.sin(u)*10*(Math.cos(v)),
                    Math.sin(v)+Math.cos(u)*10*(Math.cos(v)),
                    Math.cos(v)+10*(Math.sin(v))*Math.sin(u))
            )
        }
	}
	
    var shape = BABYLON.Mesh.CreateLines('Shape', points, scene, true);
