Both of the items are using different scales (e.g. item 1 = gl.glScalef(.25f, .25f, 1f) where as item 2 = gl.glScalef(.10f, .10f, 1f))

For detecting the collision between the two items, am I correct in assuming for the width and height values I use the scaled values ?? e.g. for item 1, the width is .25f?
