Second Edition in C Bug List (March 2001)

** Note: This bug list is for the "Second Edition in C" only.
** If your book's cover is not marked "Second Edition in C", you should
** use the "Second Edition (in Pascal)" bug list.

Like the bug list for the original "Second Edition" (in Pascal), this
bug list is divided into parts.  Each part i applies to the 1st through
i-th printings.  Thus, if you have a 1st printing, you should check all
parts of the list.

You can tell which printing you have by matching the beginning of the
bottommost line of your copy's page iv (the unnumbered page that
contains the copyright notice) with one of these: 
	
	Beginning of line	Printing	Applicable list parts

	1 2 3 4 5 6 7 8 9 10	1st		1

** Note: The authors have not seen all the printings for the
** Second Edition in C , so there is only one part to the bug list.

Each entry in the bug list is preceded by its page number. Negative line 
numbers are counted up from the bottom of the last given part (page, section,
para, bullet, column, figure caption, color plate caption, or exercise), 
where line -1 is the bottommost line of the part.  Each paragraph is counted 
in our numbering scheme, including partial ones.

If you find a bug that is not on this list (or a problem with the list
itself), please tell us about it by sending email to graphtext@cs.brown.edu
with a subject line of "Report-Text-Bug".  Please indicate whether you
are using the C version or the Pascal version of the book, and the
printing.  The current version of this list may be obtained by sending
email to the same address with a subject of "Get-Text-Bug-List".

++1 		PART 1: CORRECTIONS TO 1ST PRINTING ONLY

-- Preface

-- Chapter 1

-- Chapter 2

46, para 3, line 1: Delete "in the device parameter" (since the device
	is now returned by the function itself).

-- Chapter 3

115, line 1: "succesful" -> successful"
117, Fig. 3.41, line 6: Delete ";" after "ymax)" 
123, Fig. 3.45, line 13: "else  /* A new tL has been found */" 
	-> "else if (t < tL)  /* A new tL has been found */"
138, Fig. 3.59: Unfiltered half is too dark. 

-- Chapter 4

-- Chapter 5

211, para 2, line 5: "primitves" -> "primitives"
217, para 1: Equation at end of paragraph is missing its number: "(5.48)".
227, Ex. 5.17, line 1: "5.4" -> "5.5"

-- Chapter 6

234, Fig. 6.7: The unit cube's isometric projection should be
	be a regular hexagon.
235, Fig. 6.10(b): Each edge of the projected cube should have 
	the same length.
250, Sec. 6.3.3 should be numbered Sec. 6.3.2. 
253, Sec. 6.3.4 should be numbered Sec. 6.3.3. 
258, para -2, line 2: "roman M" -> "italic M"
270, Fig. 6.54(a): Arrows for y = (v sub max - v sub min) / 2 and for
	y = -(v sub max - v sub min) / 2 should point to the view plane's
	top and bottom edges, not to the top and bottom of the
	back clipping plane. (This new bug resulted from
	an attempt to fix a similar bug in the Pascal edition.  The
	old incorrect arrows previously pointed to the view volume's
	top and bottom planes and were incorrectly moved to point to the top
	and bottom of the back clipping plane, instead of the top and
	bottom of the view plane.)
275, para -1, line -3: "roman N" -> "italic N"
278, Section 6.5.5, line -4 (two lines before Eq. 6.54):
	"z sub z.min" -> "z sub v.min"

-- Chapter 7

-- Chapter 8

354, line 1: "Green [GREE85]" -> "Greene [GREE85c]"

-- Chapter 9

-- Chapter 10

-- Chapter 11

497, Eq. (11.43): In each term, swap the order in which the P and B factors
	appear (e.g., the first term becomes B sub (i-3,4) (t) dot 
	P sub (i-3). [This is only for consistency with the other equations 
	(e.g., Eq. 11.36) and is not strictly necessary since P and B are
	both reals.]

-- Chapter 12

-- Chapter 13

596, Fig. 13.37, line 6:
	"(l + s)" -> "(1 + s)" [Lower-case "l" should be the numeral "1"]

-- Chapter 14

-- Chapter 15

650-720: "Visible-surface" -> "Visible-Surface" in even-page running head.

-- Chapter 16

741, para 1, line -2: "an edge" -> "a polygon"

-- Chapter 17

827, line -2 "[HECK86a] proposes" -> "[HECK89] describes"
	(and see change to p. 1129, below) 

-- Chapter 18

-- Chapter 19

942, para 1, line -1: "edges sides" -> "edge sides"
943, line -4: "cptr---a pointer" -> "a pointer"

-- Chapter 20

-- Chapter 21

-- Appendix

1108, line -5: bold "(" and ")" should be roman
1108, line -4: "or A" -> "or (A", bold ")" should be roman
