Why it keeps warning me this compilation error?

[Brunex92]

I've been studying Babylon and my teacher asked me to do this application, which I have to get the matrix values and display on canvas linking these points with a cylinder.

But everytime I run the code, it says that there is a Compilation Error: matrix is undefined, even though it shows exactly what I need

Running on an HTML page it says that the problem is at the 93 line
 

	    	matObjects.diffuseColor = new BABYLON.Color3(matrix[i][6], matrix[i][7], matrix[i][8]);

What could be wrong?

Hey..nice usage of the GridMaterial

It is just an issue with your counter. i has to be < to matrix.length 

I cleaned your code a bit so that your teacher will be even more happy: http://www.babylonjs-playground.com/#KNMZ0#16
