- P. 222, equation 6.22 should read:

*sh_x_par = -dop_x/dop_z*

*sh_y_par = -dop_y/dop_z* - P. 222, equation 6.25 should read:

*S_par = S( 2/(u_max-u_min), 2/(v_max-v_min), 1/(F-B) )* - P. 233, line 3: the translation should read:

*T( x_v.min, y_v.min, z_v.min )* - P. 258 ff.: All references to SPHIGS routine
`SPH_setLocalTransformation`

should be replaced with the correct routine name,`SPH_setModelingTransformation`

.All references to the

`REPLACE`

value for the second parameter of this routine should be replaced with the correct value,`ASSIGN`

(references to`PRECONCATENATE`

and`POSTCONCATENATE`

appear to be correct).The description of this routine and its parameter values appears to be correct in the SPHIGS for ANSI-C manual distributed with Part 1 of the course notes.
