Incorrect Formula for Coordinate Transformations in Chp. 3.7
In chapter 3.7, the formula for transforming from homogenous coordinates to "normal" coordinates is given as:
x = \frac{x_h}{w_h}\ \ \ \ x = \frac{y_h}{w_h}\ \ \ \ x = \frac{z_h}{w_h} \bf\tag{3-5}
but it should be
x = \frac{x_h}{w_h}\ \ \ \ y = \frac{y_h}{w_h}\ \ \ \ z = \frac{z_h}{w_h} \bf\tag{3-5}
