Just create grid mesh with 6 vertices and feed it with the image you want as
a texture.
You can use:
* Javascript Patch to generate vertices w=3, h=2:
function (__structure Vertices) main (__number w, __number h) {
var result = new Object()
var vs = new Array()
var k = 0;
w--;
h--;
for (var i = 0; i <= h; i++)
for (var j = 0; j <= w; j++)
vs[k++] = new Array(j / w, i / h, 0);
// update vertices here: middle top - vs[1], middle bottom vs[4]
result.Vertices = vs;
return result;
}
* Grid Indices Generator: X Count = 3, Y Count = 2
* Mesh Creator with vertices from Javascript patch and indices from indices
generator and texture as your image/video
Let know if you run into problems.
