Guide for Authors
Scope
The journal Computer Aided Geometric Design is for researchers, scholars, and software developers dealing with mathematical
and computational methods for the description of geometric objects as they arise in areas ranging from CAD/CAM to robotics and scientific
visualization. The primary objects of interest are curves, surfaces, and volumes such as splines (NURBS), meshes, subdivision surfaces
as well as algorithms to generate, analyze, and manipulate them. This journal will report on new developments in CAGD and its applications,
including but not restricted to the following:
- Mathematical and Geometric Foundations.
- Curve, Surface, and Volume
generation.
- CAGD applications in Numerical Analysis, Computational Geometry, Computer Graphics, or Computer Vision.
- Industrial,
medical, and scientific applications.
Aims
The aim is to collect and disseminate information on computer aided geometric
design in one journal. To provide the user community with methods and algorithms for representing geometric objects. To illustrate computer
aided geometric design by means of interesting applications. To combine curve and surface methods with computer graphics. To explain
scientific phenomena by means of visualization. To concentrate on the interaction between theory and application. To expose unsolved
problems of the practice.
Manuscript types
The journal considers original research articles, short communications and application
briefs for publication. Short communications and application briefs should not exceed 4 printed pages.

General
The journal welcomes contributions
of the letter type: concise articles which need rapid publication. A typical manuscript consists of 10 journal pages, usually corresponding
to around 5000 words plus a few figures and tables.
It is essential to give a fax number and e-mail address when submitting a manuscript.
Articles must be written in good English.
Submission of an article implies that the work described has not been published previously
(except in the form of an abstract or as part of a published lecture or academic thesis), that it is not under consideration for publication
elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was
carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, without
the written consent of the Publisher.
Upon acceptance of an article, Authors will be asked to transfer copyright (for more information
on copyright see  http://elsevier.com/authors). This transfer will ensure the widest possible dissemination of information.
A letter will be sent to the corresponding Author confirming receipt of the manuscript. A form facilitating transfer of copyright will
be provided.
If excerpts from other copyrighted works are included, the Author(s) must obtain written permission from the copyright
owners and credit the source(s) in the article. Elsevier has pre-printed forms for use by Authors in these cases; contact Elsevier's
Rights Department, Oxford, UK: phone (+44) 1865 843830, fax (+44) 1865 853333, e-mail permissions@elsevier.com. Requests
may also be completed on-line via the Elsevier homepage ( http://www.elsevier.com/locate/permissions).
Should Authors
be requested by the Editor to revise the text, the revised version should be submitted within three months in case of a minor revision,
or within six months in case of a major revision. After this period, the article will be regarded as a new submission.
Submission
to the journal prior to acceptance
One copy of the manuscript, including one set of high-quality original illustrations, suitable
for direct reproduction, should be submitted.
On-line submission to the journal prior to acceptance
Submission to this journal
proceeds totally on-line. Use the following guidelines to prepare your article. Via the Elsevier website ( http://elsevier.com/authors)
you will be guided stepwise through the creation and uploading of the various files. Once the uploading is done, our system automatically
generates an electronic (PDF) proof, which is then used for reviewing. All correspondence, including notification of the Editor's decision
and requests for revisions, will be by e-mail. In general, no separate proof is sent to you: the PDF is your proof. A proof will be provided
only when the final layout of the article has to differ significantly from that in the initial PDF.
The above represents a very brief
outline of this form of submission. It can be advantageous to print this section of the Guide for Authors from the site for reference
in the subsequent stages of article preparation.
General points
We accept most word-processing formats, but Word, WordPerfect or LaTeX is preferred. Always keep a backup copy of the electronic file
for reference and safety. Save your files using the default extension of the program used.
Word processor documents
It is
important that the file be saved in the native format of the word processor used. The text should be in single-column format. Keep the
layout of the text as simple as possible. Most formatting codes will be removed and replaced on processing the article. In particular,
do not use the word processor's options to justify text or to hyphenate words. However, do use bold face, italics, subscripts, superscripts
etc. Do not embed graphically designed equations or tables, but prepare these using the word processor's facility. When preparing tables,
if you are using a table grid, use only one grid for each individual table and not a grid for each row. If no grid is used, use tabs,
not spaces, to align columns. The electronic text should be prepared in a way very similar to that of conventional manuscripts (see also
the Elsevier website at http://elsevier.com/authors). Do not import the figures into the text file but, instead, indicate
their approximate locations directly in the electronic text and on the manuscript. See also the section on the Preparation of electronic
illustrations.
To avoid unnecessary errors you are strongly advised to use the spellchecker function of your word processor.
Latex
documents
If the LaTeX file is suitable, proofs will be produced without rekeying the text. The article should preferably be written
using Elsevier's document class 'elsart', or alternatively the standard document class 'article'.
The Elsevier Latex package (including
detailed instructions for Latex preparation) can be obtained from the Elsevier website: http://elsevier.com/latex. It consists
of the files: elsart.cls, guidelines for users of elsart, a template file for quick start, and the instruction booklet Preparing articles
with Latex.
Because of technical complications which can arise by converting colour figures to 'grey scale' (for the printed version,
should you not opt for colour in print), please submit in addition usable black and white prints corresponding to all the colour illustrations.
Presentation of manuscript
Please write your text in good English (American or British usage
is accepted, but not a mixture of these). Use decimal points (not commas); use a space for thousands (10 000 and above).
Language
Editing. International Science Editing and Asia Science Editing can provide English language and copyediting services to authors
who want to publish in scientific, technical and medical journals and need assistance before they submit their article or, before it
is accepted for publication. Authors can contact these services directly: International Science Editing ( http://www.internationalscienceediting.com)
and Asia Science Editing ( http://www.asiascienceediting.com) or, for more information about language editing services, please
contact authorsupport@elsevier.com who will be happy to deal with any questions.
Please note Elsevier neither endorses
nor takes responsibility for any products, goods or services offered by outside vendors through our services or in any advertising. For
more information please refer to our terms and conditions ( http://elsevier.com).
Title page. Provide the following
data on the title page (in the order given):
- Title.
- Author names and affiliations; corresponding author; present
and permanent addresses.
- Abstract.
- Keywords.
Title. Concise and informative. Titles are
often used in information-retrieval systems. Avoid abbreviations and formulae where possible.
Author names and affiliations.
Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses
(where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the
author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name,
and, if available, the e-mail address of each author.
Corresponding author. Clearly indicate who is willing to handle correspondence
at all stages of refereeing and publication, also post-publication. Ensure that telephone and fax numbers (with country and area code)
are provided in addition to the correct e-mail address and the complete postal address.
Present/permanent address. If an author
has moved since the work described in the article was done, or was visiting at the time, a 'Present address' (or 'Permanent address')
may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main,
affiliation address. Superscript Arabic numerals are used for such footnotes.
Abstract. A concise and factual abstract is
required. The abstract should state briefly the purpose of the research, the principal results and major conclusions. An abstract is
often presented separate from the article, so it must be able to stand alone. References should therefore be avoided, but if essential,
they must be cited in full, without reference to the reference list.
Non-standard or uncommon abbreviations should be avoided, but
if essential they must be defined at their first mention in the abstract itself.
Keywords. Immediately after the abstract,
provide 3-5 keywords, avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of'). Be sparing with abbreviations:
only abbreviations firmly established in the field may be eligible. These keywords will be used for indexing purposes.
Abbreviations.
Define abbreviations that are not standard in this field at their first occurrence in the article: in the abstract but also in the main
text after it. Ensure consistency of abbreviations throughout the article.
Subdivision of the article. After the abstract,
divide your article into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, ?), 1.2, etc.
(the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to 'the
text.' Any subsection may be given a brief heading. Each heading should appear on its own separate line.
Appendices. If there
is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering:
(Eq. A.1), (Eq. A.2), etc.; in a subsequent appendix, (Eq. B.1) and so forth.
Acknowledgements. Place acknowledgements before
the references, in a separate section, and not as a footnote on the title page.
Preparation of supplementary data
Elsevier
now accepts electronic supplementary material (e-components) to support and enhance your scientific research. Supplementary files offer
the author additional possibilities to publish supporting applications, movies, animation sequences, high-resolution images, background
datasets, sound clips and more. Supplementary files supplied will be published online alongside the electronic version of your article
in Elsevier Web products, including ScienceDirect ( http://www.sciencedirect.com).
In order to ensure that your submitted
material is directly usable, please ensure that data is provided in one of our recommended file formats. Authors should submit the material
in electronic format together with the article and supply a concise and descriptive caption for each file. For more detailed instructions
please visit the Elsevier website ( http://elsevier.com/authors) and read our artwork instruction pages ( http://elsevier.com/artworkinstructions).
Files can be stored on 3 1/2 inch diskette, ZIP-disk or CD (either MS-DOS or Macintosh). This journal offers electronic submission
services and supplementary data files can be uploaded via the Elsevier website ( http://elsevier.com/authors).
References
Responsibility for the accuracy of bibliographic citations lies entirely with the authors.
Citations in the text. Please
ensure that every reference cited in the text is also present in the reference list (and vice versa). Any references cited in the abstract
must be given in full. Unpublished results and personal communications should not be in the reference list, but may be mentioned in the
text. Citation of a reference as 'in press' implies that the item has been accepted for publication.
Citing and listing of web
references. As a minimum, the full URL should be given. Any further information, if known (author names, dates, reference to a source
publication, etc.), should also be given. Web references can be listed separately (e.g., after the reference list) under a different
heading if desired, or they can be included in the reference list.
Text. All citations in the text should refer to:
1. (in case of a single author) the author's name (without initials, unless there is ambiguity) and the year of publication;
3. (in
case of two authors) both authors' names and the year of publication;
3. (in case of three or more authors) the first author's name
followed by 'et al.' and the year of publication.
Citations may be made directly (or parenthetically). Groups of references should
be listed first alphabetically, then chronologically.
Examples: 'as demonstrated (Allan, 1996a, 1996b, 1999; Allan and Jones, 1995).
Kramer et al. (2000) have recently shown ....'
List. References should be arranged first alphabetically and then further sorted
chronologically if necessary. More than one reference from the same author(s) in the same year must be identified by the letters 'a',
'b', 'c', etc., placed after the year of publication.

Preparation of electronic illustrations
Submitting your artwork in an electronic format helps us to produce your work to the best possible standards, ensuring accuracy, clarity
and a high level of detail.
General points
- Always supply high-quality printouts of your artwork, in case conversion
of the electronic artwork is problematic.
- Make sure you use uniform lettering and sizing of your original artwork.
- Save
text in illustrations as 'graphics' or enclose the font.
- Only use the following fonts in your illustrations: Arial, Courier,
Helvetica, Times, Symbol.
- Number the illustrations according to their sequence in the text.
- Use a logical naming convention
for your artwork files and supply a separate listing of the files and the software used.
- Provide all illustrations as separate
files and as hardcopy printouts on separate sheets.
- Provide captions to illustrations separately.
- Produce images near
to the desired size of the printed version.
Non-electronic illustrations
Provide all illustrations as high-quality
printouts, suitable for reproduction (which may include reduction) without retouching. Number illustrations consecutively in the order
in which they are referred to in the text. They should accompany the manuscript, but should not be included within the text. Clearly
mark all illustrations on the back (or on the lower front side in case of line drawings) with the figure number and the Author's name
and, in cases of ambiguity, the correct orientation.
Mark the appropriate position of a figure in the article
Captions
Ensure that each illustration has a caption. Supply captions on a separate sheet, not attached to the figure. A caption should comprise
a brief title (not on the figure itself) and a description of the illustration. Keep text in the illustrations themselves to a minimum
but explain all symbols and abbreviations used.
Line drawings
Supply high-quality printouts on white paper produced with black
ink. The lettering and symbols, as well as other details, should have proportionate dimensions, so as not to become illegible or unclear
after possible reduction; in general, the figures should be designed for a reduction factor of two to three. The degree of reduction
will be determined by the Publisher. Illustrations will not be enlarged. Consider the page format of the journal when designing the illustrations.
Photocopies are not suitable for reproduction. Do not use any type of shading on computer-generated illustrations.
Photographs (halftones)
Please supply original photographs for reproduction, printed on glossy paper, very sharp and with good contrast. Remove non-essential
areas of a photograph. Do not mount photographs unless they form part of a composite figure. Where necessary, insert a scale bar in the
illustration (not below it), as opposed to giving a magnification factor in the legend.
Note that photocopies of photographs are
not acceptable.
Submit colour illustrations as original photographs, high-quality computer prints or transparencies, close to the
size expected in publication, or as 35 mm slides. Please make sure that artwork files are in an acceptable format (TIFF, EPS or MS Office
files) and with the correct resolution. Polaroid colour prints are not suitable. If, together with your accepted article, you submit
usable colour figures then Elsevier will ensure, at no additional charge, that these figures will appear in colour on the Web (e.g.,
ScienceDirect and other sites) regardless of whether or not these illustrations are reproduced in colour in the printed version. For
colour reproduction in print, you will receive information regarding the costs from Elsevier after receipt of your accepted article.
Please indicate your preference for colour in print or on the Web only. For further information on the preparation of electronic artwork,
please see http://elsevier.com/artworkinstructions.
