Introduction

cor · ri · gen · dum n., pl. -da.
1. An error to be corrected, esp. a printer's error. 2. corrigenda. A list of errors in a book along with their corrections. [Lat., neut. gerundive of corrigere, to correct. See "correct."] (The American Heritage College Dictionary, Third Edition.)

This page contains a collection of updates and corrections (errata) to print and digital publications produced by ACM SIGGRAPH. We regret any inconvenience caused by these inaccuracies, and strive to make corrections available as best we can. If you know of inaccuracies in an article you helped to author, published by ACM SIGGRAPH, and wish to have corrections made public in this forum, please contact Stephen Spencer, ACM SIGGRAPH Director for Publications at spencer@siggraph.org.

ACM TIG 23(3) (ACM SIGGRAPH 2004 Conference Proceedings)

Figure 8 on the back cover is not reproduced in its entirety. It can be seen, in full, as Figure 17 on page 914.

The final page number on the spine of the book is incorrect. The correct final page number is 928.

ACM TOG 22(3) (ACM SIGGRAPH 2003 Conference Proceedings)

Several names were inadvertantly omitted from the author index. A corrected version (48KB PDF) is available.

ACM SIGGRAPH 2003 Electronic Art & Animation Catalog

Computer Animation Festival, p. 216-217: under Research and Development, Colette Mullenhoff's name should have been listed. ESC regrets the error in omission.

Symposium on Computer Animation 2003

Wei, Zhao, Fan, Li, Yoakum-Slover and Kaufman: "Blowing in the Wind," pp. 75-85 and 366.

Unembedded typefaces in the color plate page result in hard-to-read captions.

Color Plate 3's caption should read:

Streamlines originating from a vertical plane cuts through the most active flow area. Red (green) lines indicate flow toward (away from) the viewer, and blue lines indicate the flow in the plane.

Color Plate 4's caption should read:

Streamlines originating from a plane cutting through the most active flow area. Pink (light green) lines indicate upward (downward) flow. Gray lines indicate horizontal flow.

A corrected version (6.5MB PDF) of the color plate page is available to download.

  Equations 4, 5, and 6 as printed in the paper suffer from roundoff errors. The equations, as originally printed and corrected, appear below.

  Equation 4 (original)
  Y = 0.13X⁶ - 3.16X⁵+31.5X⁴-155.87X³+394X²-465.95X+200.36

  Equation 4 (corrected)
  Y = 0.1251X⁶-3.1619X⁵+31.5032X⁴-155.8713X³+394.0271X²-465.9513X+200.3621

  Equation 5 (original)
  Y = 0.0003X²-0.18X+32

  Equation 5 (corrected)
  Y = c1*X² + c2*X + c3, where c1 = 2.5524e-4, c2 = -0.1763, and c3 = 32.2815

  Equation 6 (original)
  Y=-0.0034X³+0.23X²-6.7X+79

  Equation 6 (corrected)
  Y = d1*X⁴ + d2*X³ + d3*X² + d4*X + d5, where d1 = 1.8798e-5, d2 = -0.0034, d3 = 0.2262, d4 = -6.7021, and d5 = 78.831.

  After this paper was accepted for SIGGRAPH 2000, earlier work done by H. L. Lim was brought to the authors' attention. In order that the previous work be properly credited, the authors modified their paper to reflect this previous work. Their extended paper is available (1.2MB Adobe Acrobat PDF document) as well as their original paper (1.0MB Adobe Acrobat PDF document) as it was accepted and printed in the ACM SIGGRAPH 2000 Conference Proceedings publications.

• Zongker, Wade and Salesin: "Example-Based Hinting of TrueType Fonts," pp. 411-416.
  
  The ACM copyright notice on page 411 obscures the paper's first footnote, reproduced here in its entirety:

  Hinters express font sizes in "pixels per em," or "ppem." This measure counts the number of device pixels in the em of the font. In traditional typography, the em of a font was the height of the metal block of type. With digital typography, there is no actual metal block to measure, but the digital outlines are still expressed in coordinates relative to this hypothetical size. The point size of text refers to the size of its em expressed in points (a point is 1/72 of an inch). Thus, 12-point text corresponds to 12 ppem on a 72 dpi screen, or 100 ppem on a 600 dpi printer.

  The caption for Figure 15(b) on page 509 is incorrect. It should read:
