Page 39: Note, the matrix, "E", computed here is the inverse of the matrix often called the "lookAt" matrix in many graphics contexts.Page 39: The computation for the coordinate vectors should be
z = normalize(p - q)
x = normalize(u × z)
y = (z × x)
where
normalize(c) = c / sqrt( c21+ c22+ c23)

Page 62: Right invariance, in contrast, means that the interpolation of an object does not change ...Chapter 12
Page 114: If the three vertices are counterclockwise in the plane, then c will be in the +z direction. Otherwise, it will be in the -z direction.Minor Errors
The book often uses the word "degrees", when it should be using "radians".Chapter 1
Page 3: should read: "known as OpenGL "Chapter 3
Page 11: "if there exists non-zero scalars a1...an" => "if there exists scalars, a1...an, not all zero"Page 23: "Similar to the case of linear transform ..." => "Similar to the case of linear transformations ..."
Page 25: The third row of the rightmost matrix should read "i j k 0", not "h i j 0".
Chapter 4
Page 29: "this does not fully specified ..." => "this does not fully specify"Chapter 6
Page 45: "it is useful to return the identity matrix from the default constructor." => "it is useful for the default constructor to set the matrix as the identity."Page 46: "any face that is backfacing to the eye." (Add period)
Page 46: "We use a global variable "Matrix4 eyeRbt" to represent the rigid body matrix E that relates the object's..." => "We use a global variable "Matrix4 eyeRbt" to represent the rigid body matrix E that relates the eyes's ..."

Page 68: "(q1 * inv(q0)" => "(q1 * inv(q0))"Chapter 14
Page 128: "simulate this Process" => "simulate this process"Page 134: "toLight = normalize(toLight);" is unnecessary
Chapter 15
Page 128: "2r-1" => "2*r-1"Chapter 19
Page 176: "The lasso curve is parameterized "Page 183: Note that the original color matching experiments used the wavelenghts: 436, 546, 700, not 435,545,625.
Page 194: The funny symbols in figure 19.10 should just be ellipses (three dots).
