Left hand 1st column

1st para references 2 kinds of surface models, Nurb and Point Cloud Based.
rest of 1st para and 2nd para explain what and how Nurb works.
No explanation what point cloud based follows
then in 4th para a 3rd type of surface model 'T-Spline" is introduced - But no explanation provided.

So What is needed
1) what Point Cloud Based is needs to be provided and if your going to intro T-Spline then that should be part of 1 para and what T-Spline is provided.

Also 5th para discusses "Watertight", no explanation is given what this is, however on page 23 & 24 there is a tutorial covering "Seal Up the Bunny".
if your not going to explain what Watertight is in this para, at least give reference to page 23,24.

top left figure P-6 and bottom left figure P=7

The figure P-6 labels the x axes as front to back which does not agree with your description of the x axes on the previous page

The figure P-6 should be labeled as follows:

x = left to right

y = front to back

z= up and down

Figure P-7 should be changed as follows:

xy is correct

xz should be yz

yz should be xz
