jit.gl.text3d matrix out

    I'm trying to find the bounds of a character or characters displayed in jit.gl.text3d so I can draw a rectangle behind it. It seems that a matrixoutput from text3d would have this information somewhere, however, I'm not clear how to parse the matrix that comes from a text3d...

      I just noticed that jit.gl.text3D outputs one frame for each letter, which has confused me in the past. You will need to accumulate this list to get min/max bounds for a whole sentence. ie.
