Three-dimensional OBJ and PLY models in online journal articles
About the 3D viewer for OBJ and PLY models
Authors of selected Elsevier journals are invited to enrich their online articles by providing supplementary 3D models in OBJ and PLY formats, which will be visualized using the interactive 3D viewer embedded within the article.
Using the 3D viewer, the reader can select models, zoom into the model, rotate and pan the model, change display settings, and download original data files. It is also possible to open the 3D viewer in a new window and to view the model in a stereo mode using anaglyph glasses.
This 3D viewer was developed in collaboration with Kitware SAS. It supports all major browsers and mobile devices.

Benefits for authors and readers
Innovating & Enriching Content
For almost 350 years, academic articles have been published in a similar layout – a format which starts with an abstract and ends with a conclusion and a list of references. Articles were presented in this way with the reader of the printed version in mind. However most researchers now access articles online, which means that readership styles and how information is gathered have changed.
We are adapting to these changes because we want to help authors improve how their research is presented online and readers to gain deeper insights faster. Offering the 3D viewer for OBJ and PLY models in our journals is just one of the ways we are doing this.
The 3D viewer functionality enables authors to enrich and extend their article by providing a possibility to interactively explore 3D reconstructions of scientific data discussed in the article. This helps readers to quickly understand the relevance of a research paper and to visualize research data for deeper insights.
Supported data formats
As it was mentioned above, two data formats are supported by this 3D viewer: PLY and OBJ.
PLY is a 3D data format known as the Polygon File Format or the Stanford Triangle Format. This format was principally designed to store three dimensional data from 3D scanners. The format specification can be found here.
OBJ is a geometry definition file format developed by Wavefront Technologies for its Advanced Visualizer animation package. The format specification can be found here.
It is also possible to upload material (MTL) and regular texture files (JPG/PNG).
MTL is an auxiliary file containing definitions of materials that may be accessed by an OBJ file.
Submission & publication
Multiple 3D models can be submitted. Each model will have to be uploaded to the online submission system via the "3D models" submission category as a single zip file, irrespective of whether it's just a single PLY/OBJ file or a more complex model consisting of material (MTL) and texture (PNG/JPG) files.
Please be advised that the recommended model size before zipping is 50-100 MB with the absolute maximum limit of 200 MB. The same holds for texture files.Please provide a short informative description for each model by filling in the "Description" field when uploading a dataset.
Note: 3D models will be available for download from the online article on ScienceDirect. If you have concerns about your model being downloadable, please provide a video instead.
3D models will be provided in the online version of the article. The PDF/printed version of the article will feature static figures only (if those figures are included in the article manuscript).
