the indice of Height and Y are wrong.

Line 31 should be minmaxPoint.max[1] - minmaxPoint.min[1]; Line 35 should be var offsetY = height / 2 + minmaxPoint.min[1]; Line 40, 41 should be minmaxPoint.min[2] and minmaxPoint.max[2]

Line 62 should be + offsetY / tileHeight * latitudeExtent; Line 64 should be + offsetY / tileHeight * latitudeExtent; (use plus sign instead of minus sign)

My output seems to be tilted 90 degrees on the roll axis. I tried your patch but it seems it did not make a difference.
