about.me: about social networks series

about.me is a personal web hosting service [...]. The site offers registered users a simple platform from which to link multiple online identities, relevant external sites, and popular social networking websites such as Facebook, Flickr, Google+, Pinterest, LinkedIn, Twitter, Tumblr, and YouTube.

It is characterized by its one-page user profiles, each with a large, often-artistic background image and abbreviated biography.

Academia.edu: about social networks series

Academia.edu is an American commercial social networking website for academics. The website allows its users to create a profile, upload their work(s), and select areas of interest. Then the user can browse the networks of people with similar interests.

As of October 2019, Academia.edu claims just over 99 million users. Although Academia.edu it is not an open access repository per se), the platform can be used by scholars to share papers, monitor readership and paper impacts as measured by Academia.edu's own metrics, and for users to follow scholars or research in specific fields.

The site was launched in September 2008, with 39 million unique visitors per month as of January 2019 and over 21 million uploaded texts.

Accutrans 3D - A powerfull 3D converter

Accutrans 3d

A new tool on babelX3D Tools-Tutorials page list.

Accutrans 3D provides accurate translation of 3D geometry between the file formats used by many popular modeling programs.

A tool to convert between 3D formats

This is a perfect complement companion for Vivaty Studio users. Remember the plugin Vivaty Studio uses to export/import 3D formats? It uses Accutrans 3D technology.

That plugin is very usefull and Accutrans 3D is even better since it is the updated full version of that plugin with more formats and options (also less bugs). When some specific files throw an error when imported by Vivaty plugin that can be fixed with the full Accutrans 3D program.

Although not a free program (as their authors say), Accutrans 3D can be downloaded and fully used, indefinitely.

»Download from micromouse.ca/

Alternative software: an alternative converter is MeshLab also available on babelX3D Tools-Tutorials page list.

Add a Play Button and Cover Image to WebGL launch

Hi all,

With Unity default WebGL template the scene created loads immediately when the HTML page opens. One may whish to have the option to proceed or not with the loading in a process similar to online videos with a cover image and a play button. The cover image is useful to promote the scene.

A Video Style Viewer for WebGL Scenes

Demo: http://odisseia.babelx3d.net/Unity3DTests/WebGLTemplates/Babel_Default/index.html

Features:

Cover Image to publicize the scene theme,
Play Button to start the scene loading,
Window Resize on bottom right corner. Before loading the user can resize the scene window to a better fit.
Other small tweaks; among them a message "Loading ..." to reassure in case of slow downloads and a url command to start the scene immediately in case we need it; details and example below.

If, for some reason, in a specific situation we want to start the scene immediately? Just add "?start=yes" to the URL, like this:
http://odisseia.babelx3d.net/Unity3DTests/WebGLTemplates/Babel_Default/index.html?start=yes

The wait time can be defined by using in the URL command a value in milliseconds instead of the yes argument. Examples: with "?start=5000" waits 5 seconds; with "?start=0" there is no wait and the scene is loaded immediately without showing the Cover Image, see below link.
http://odisseia.babelx3d.net/Unity3DTests/WebGLTemplates/Babel_Default/index.html?start=0

Check our blog for more details and download the package to install in your Unity project:

Enjoy!
