This template is for papers of VGTC-sponsored conferences such as IEEE VIS, IEEE VR, and ISMAR which are published as special issues of TVCG.
The template does not contain the respective dates of the conference/journal issue, these will be entered by IEEE as part of the publication production process.
Therefore, \textbf{please leave the copyright statement at the bottom-left of this first page untouched}.
\section{Author Details}
You should specify ORCID IDs for each author (see \url{https://orcid.org/} to register) for disambiguation and long-term contact preservation.
Use \verb|\authororcid{Author Name}{0000-0000-0000-0000}| for each author, replacing the ``Author Name'' and using the 16-digit (hyphenated) ORCID ID for the second parameter.
The template shows an example without ORCID IDs for two of the authors.
ORCID IDs should be provided in all cases.
Each author's affiliations have to be provided in the author footer on the bottom-left corner of the first page.
It is permitted to merge two or more people from the same institution as long as they are shown in the same order as in the overall author sequence on the top of the first page.
For example, if authors A, B, C, and D are from institutions 1, 2, 1, and 2, respectively, then it is ok to use 2 bullets as follows:
\begin{itemize}
\item A and C are with Institution 1. E-mail: \{a\,$|$\,c\}@i1.com\,.
\item B and D are with Institution 2. E-mail: \{b\,$|$\,d\}@i2.org\,.
\end{itemize}
\section{Hyperlinks and Cross References}
The style uses the \verb|hyperref| package which can typeset clickable hyperlinks using \verb|\href{...}{...}|, hyperlinked URLs using \verb|\url{...}|, and turns references into internal links.
The style also uses \verb|cleveref| to automatically and consistently format cross references.
We recommend that you use the \verb|\cref{label}| and \verb|\Cref{label}| calls instead of \verb|Figure~\ref{label}| or similar.
\verb|\Cref| should be used when starting a sentence to spell out the reference (e.g.\ ``Section'') while \verb|\cref| should be used when referencing within a sentence to abbreviate (e.g.\ ``Sec.'').
Here are examples for use within a sentence: \cref{fig:vis_papers}, \cref{tab:vis_papers}, \cref{sec:supplement_inst,sec:references_inst}, \cref{eq:sum}.
The following sentences all start with a reference, so use \verb|\Cref|.
\Cref{fig:vis_papers} is a \verb|figure| environment.
\Cref{tab:vis_papers} is a \verb|table| environment.
\Cref{sec:supplement_inst,sec:references_inst} are \verb|section| environments.
\Cref{eq:sum} is an \verb|equation| environment.
\section{Figures}
\subsection{Loading figures}
The style automatically looks for image files with the correct extension (eps for regular \LaTeX; pdf, png, and jpg for pdf\LaTeX), in a set of given subfolders defined above using \verb|\graphicspath|: figures/, pictures/, images/.
It is thus sufficient to use \verb|\includegraphics{clouds}| (instead of \verb|\includegraphics{figs/clouds.jpg}|).
Figures should be in CMYK or Grey scale format, otherwise, colour shifting may occur during the printing process.
\subsection{Vector figures}
Vector graphics like \texttt{pdf} and \texttt{eps} (can be generated from a \texttt{svg}) are best for charts and other figures with text or lines.
They will look much nicer and crisper and any text in them will be more selectable, searchable, and accessible.
\subsection{Raster figures}
Of the raster graphics formats, screenshots of user interfaces and text, as well as line art, are better shown with \texttt{png}.
\texttt{jpg} is better for photographs.
Make sure all raster graphics are captured in high enough resolution so they look crisp and scale well.
\subsection{Alt texts}
Add alternative texts that describe the content of the image to all figures.
\subsection{Figures on the first page}
The teaser figure should only have the width of the abstract as the template enforces it.
The use of figures other than the optional teaser is not permitted on the first page.
Other figures should begin on the second page.
Papers submitted with figures other than the optional teaser on the first page will be refused.
\subsection{Subfigures}
You can add subfigures using the \texttt{subcaption} package that is automatically loaded.
Inside a \verb|figure| environment, create a \verb|subfigure| environment.
See \cref{fig:ex_subfigs} for an example.
You can reference individual figures, either fully using \verb|\cref| (\cref{fig:ex_subfigs_a,fig:ex_subfigs_b}) or by letter using \verb|\subref|.
E.g., \subref{fig:ex_subfigs_b}, \subref{fig:ex_subfigs_c}.
Note that \verb|\subref| only works for one label at a time.

\subsection{Figure Credits}
\label{sec:figure_credits_inst}
In the \hyperref[sec:figure_credits]{Figure Credits} section at the end of the paper, you should credit the original sources of any figures that were reproduced or modified.
Include any license details necessary, as well as links to the original materials whenever possible.
For credits to figures from academic papers, include a citation that is listed in the \textbf{References} section.
An example is provided \hyperref[sec:figure_credits]{below}.
\section{Equations and Tables}
Equations can be added like so:
\begin{equation}
\label{eq:sum}

\section{Supplemental Material Instructions}
\label{sec:supplement_inst}
In support of transparent research practices and long-term open science goals, you are encouraged to make your supplemental materials available on a publicly-accessible repository.
Please describe the available supplemental materials in the \hyperref[sec:supplemental_materials]{Supplemental Materials} section.
These details could include (1) what materials are available, (2) where they are hosted, and (3) any necessary omissions.
\section{Reporting of User Studies}
Please note that for the reporting of any experimental results that involve human participants you are \textbf{required} to ``include a statement in the article that the research was performed under the oversight of an institutional review board or equivalent local/regional body, including the official name of the IRB/ethics committee, or include an explanation as to why such a review was not conducted. For research involving human subjects, authors shall also report that consent from the human subjects in the research was obtained or explain why consent was not obtained'' \cite[Section 8.1.1.E]{IEEEPublications2025}. Ideally, for an IRB approval or similar, you include the case number under which the permission was granted. For instance:
``Our experiment was approved by our university's IRB (No. 12345678). [...] At the start of the experiment, we obtained informed consent from all participants, who filled in and signed a consent form (which we share in our additional materials).''
\section{References}
\label{sec:references_inst}
An example of the reference formatting is provided in the \textbf{References} section at the end.
\subsection{Include DOIs}
\label{sec:references_inst:doi}
All references which have a DOI (which are virtually all entries of a list of references today), by default, should have it included in the bib\TeX\ file such that they are displayed in the list of references (as a courtesy for your reviewers and your readers).
The DOI can be entered with or without the \url{https://doi.org/} prefix. Note that you can also use short DOIs; for these use the interface from \href{https://shortdoi.org/}{\texttt{shortdoi\discretionary{}{.}{.}org}} to obtain a short version of any valid DOI, as showcased in the example \textbf{References} section at the end of the template.
\subsection{Narrow DOI option}
The \verb|-narrow| versions of the bibliography style use the font \verb|PTSansNarrow-TLF| for typesetting the DOIs in a compact way.
This font needs to be available on your \LaTeX\ system.
It is part of the \href{https://www.ctan.org/pkg/paratype}{\texttt{paratype} package}, and many distributions (such as MikTeX) have it automatically installed.
If you do not have this package yet and want to use a \verb|-narrow| bibliography style then use your \LaTeX\ system's package installer to add it.
If this is not possible you can also revert to the respective bibliography styles without the \verb|-narrow| in the file name.
DVI-based processes to compile the template apparently cannot handle the different font so, by default, the template file uses the \texttt{abbrv-doi} bibliography style.
\subsection{Disabling hyperlinks}
To avoid adding hyperlinks to the references (the default) you can use \verb|\bibliographystyle{abbrv-doi}| instead of \verb|\bibliographystyle{abbrv-doi-hyperref}|.
By default, the DOI field in a bib\TeX\ entry is turned into a hyperlink.
See the examples in the bib\TeX\ file and the bibliography at the end of this template.
\subsection{Guidelines for bibTeX}
\begin{itemize}
\item All bibliographic entries should be sorted alphabetically by the last name of the first author.
This \LaTeX/bib\TeX\ template takes care of this sorting automatically.
\item Merge multiple references into one; e.\,g., use \cite{Max1995OpticalModelsDirect,Kitware2003VisualizationToolkitUsers} (not \cite{Kitware2003VisualizationToolkitUsers}\cite{Max1995OpticalModelsDirect}).
Within each set of multiple references, the references should be sorted in ascending order.
This \LaTeX/bib\TeX\ template takes care of both the merging and the sorting automatically.
\item Verify all data obtained from digital libraries, even ACM's DL and IEEE Xplore etc.\ are sometimes wrong or incomplete.
\item Do not trust bibliographic data from other services such as Mendeley.com, Google Scholar, or similar; these are even more likely to be incorrect or incomplete.
\item Articles in journal---items to include:
\begin{itemize}
\item author names
\item title
\item journal name
\item year
\item volume
\item number
\item (optionally) month of publication as variable name (i.e., \texttt{\{jan\}} for January, etc.; month ranges using \texttt{\{jan \#\{/\}\# feb\}} or \texttt{\{jan \#\{-{}-\}\# feb\}})
\end{itemize}
\item Use journal names in proper style: correct: ``\texttt{IEEE Transactions on Visualization and Computer Graphics}'', incorrect: ``\texttt{Visualization and Computer Graphics, IEEE Transactions on}'', also incorrect: ``\texttt{IEEE transactions on visualization and computer graphics}''. You can also (consistently) use the ISO4 abbreviation standard for journal names. In this case TVCG would be ``\texttt{IEEE Trans Vis Comput Graph}''. You can search for ISO4 abbreviations at \href{https://journal-abbreviations.library.ubc.ca/}{\texttt{journal\discretionary{}{-}{-}abbreviations\discretionary{}{.}{.}library\discretionary{}{.}{.}ubc\discretionary{}{.}{.}ca}} or at \href{https://woodward.library.ubc.ca/woodward/research-help/journal-abbreviations/}{\texttt{woodward\discretionary{}{.}{.}library\discretionary{}{.}{.}ubc\discretionary{}{.}{.}ca\discretionary{/}{}{/}woodward\discretionary{/}{}{/}research\discretionary{}{-}{-}help\discretionary{/}{}{/}journal\discretionary{}{-}{-}abbreviations}} (if the full journal name is not available, search for its individual words).
\item Papers in proceedings---items to include:
\begin{itemize}
\item author names
\item title
\item abbreviated proceedings name: e.g., ``\texttt{Proc.\textbackslash{} CONF\_ACRONYNM}'' \textbf{without the year}; example: ``\texttt{Proc.\textbackslash{} CHI}'', ``\texttt{Proc.\textbackslash{} 3DUI}'', ``\texttt{Proc.\textbackslash{} Eurographics}'', ``\texttt{Proc.\textbackslash{} EuroVis}''
\item year
\end{itemize}
\item Article/paper title convention: refrain from using curly brackets, except for acronyms/proper names/words following dashes/question marks etc.; example:\\\\
%
The paper ``Marching Cubes: A High Resolution 3D Surface Construction Algorithm'' should be entered as ``\texttt{\{M\}arching \{C\}ubes: A High Resolution \{3D\} Surface Construction Algorithm}'' or ``\texttt{\{M\}arching \{C\}ubes: A high resolution \{3D\} surface construction algorithm}''.
It will then be typeset as ``Marching Cubes: A high resolution 3D surface construction algorithm''.
\item For all entries:
\begin{itemize}
\item DOI (or short DOI, see \cref{sec:references_inst:doi}) can be entered in the DOI field as plain DOI number or as DOI url.
\item ``\texttt{articleno}'' plus ``\texttt{numpages}'' or ``\texttt{pages}'': Provide full page ranges \texttt{AA-{}-BB}. Alternatively, if an article number is available like for recent ACM conference publications, use that plus the corresponding number of pages instead (e.g., see the entry for Panavas et al.\ \cite{Panavas2022JuvenileGraphicalPerception}).
\end{itemize}
\item When citing references, do not use the reference as a sentence object; e.g., wrong: ``In \cite{Lorensen1987MarchingCubesHigh} the authors describe \dots'', correct: ``Lorensen and Cline \cite{Lorensen1987MarchingCubesHigh} describe \dots''
\end{itemize}
\section{Appendices}
\label{sec:appendices_inst}
Appendices can be specified using \verb|\appendix|.
For example, our Troubleshooting instructions in
\iflabelexists{appendix:troubleshooting}
{\cref{appendix:troubleshooting}}
{the appendix of the full paper at \url{https://osf.io/nrmyc}}.
Note that the paper submission has to end after the \textbf{References} section and within the page limit of the conference you are submitting to.
Any version of Appendices or the paper with Appendices included has to be submitted separately as supplementary material (not that, for IEEE VIS starting in 2026, you can optionally also submit an additional full version including the appendices).
You can use the \verb|hideappendix| class option to remove everything after \verb|\appendix|.
We encourage you to submit a full version of your paper to a preprint server with any appendices included.
You can use the \verb|\iflabelexists| macro to cross reference an appendix from the main text, but only if that label (i.e., the appendix) actually exists.
For example, above we use
\begin{verbatim}
\iflabelexists{appendix:troubleshooting}
{\cref{appendix:troubleshooting}}
{the appendix of the full paper at
\url{https://osf.io/XXXXX}}.
\end{verbatim}
In order to cross-reference to the appendix with \verb|\cref| if it exists, but if the appendix is commented out then we will simply create a hyperlinked URL to it.

\subsection{ifpdf error}
If you receive compilation errors along the lines of \texttt{Package ifpdf Error: Name clash, \textbackslash ifpdf is already defined} then please add a new line \verb|\let\ifpdf\relax| right after the \verb|\documentclass[journal]{vgtc}| call.
Note that your error is due to packages you use that define \verb|\ifpdf| which is obsolete (the result is that \verb|\ifpdf| is defined twice); these packages should be changed to use \verb|ifpdf| package instead.
\subsection{\texttt{pdfendlink} error}
Occasionally (for some \LaTeX\ distributions) this hyper-linked bib\TeX\ style may lead to \textbf{compilation errors} (\texttt{pdfendlink ended up in different nesting level ...}) if a reference entry is broken across two pages (due to a bug in \verb|hyperref|).
In this case, make sure you have the latest version of the \verb|hyperref| package (i.e.\ update your \LaTeX\ installation/packages).
If this package update does not fix the error for you, you can use the \verb|documentclass| option \verb|protectagainstpdfendlink| such as as follows:\\[1ex]
{\footnotesize\verb|\documentclass[journal]{vgtc,protectagainstpdfendlink}|}\\[1ex]
to set the \LaTeX/bib\TeX{} processing to avoid breaking reference entries in the list of references. Alternatively, you can revert back to \verb|\bibliographystyle{abbrv-doi}| (at the expense of removing hyperlinks from the bibliography) and then to try \verb|\bibliographystyle{abbrv-doi-hyperref}| again after some more editing.
