OGV/Online Geometry Viewer
Create.Share.View
Online Geometry Viewer is an online web app, where users can upload, view and share 3D CAD models. They can also host these models online, can like (love) or comment on them. In a nutshell it can be looked at as a social blogging platform for 3D models.
Online Geometry Viewer is written using metoerJS which is Real Time by default. Thus if a user comments on your model, it magically gets updated in real time and you can see it without need of any refresh or much delay.
History
The reason why this happened.
OGV started as a Google Summer of Code project in 2013 by Harmanpreet Singh. It was written in PHP on server side and HTML, CSS and Javascript on the client side. It used MySQL for database. For viewing models in web browser a webGL based library called three.js was used. Users could upload 3D models and view them in 3D online. After the GSoC 2013 was complete, there were discussions at BRL-CAD mailing list regarding infrastructure of OGV. It started with moving from vanilla PHP to using some framework and then moved towards using nodejs for OGV. Thus in GSoC 2014, another GSoC project by Inderpreet Singh aimed at moving OGV from PHP to nodejs using a full stack framework meteorjs. Few extra features mostly regarding making it social were also added.
Motivation
When we built our initial HTML web pages in 90s we din't have an img tag. Just a few years back Video was a foreign element added via third party plugins. Today images,videos and audio all have become first class citizens of the web. HTML 5 has introduced many new members to the family. Canvas, WebGL and SVG being few of them. These technologies allow us to manipulate and access 2d and 3d graphics right in the browser. Today we have incredible power in our hands when it comes to handling graphics on web. Even with technologies like WebGL, 3D graphics have not yet become a part of our daily web experience. We believe in OGV as one of those platforms that will make sharing 3D models on the web as normal as sharing videos on youtube or images on flickr.

Real Time
Online Geometry Viewer is written using metoerJS which is Real Time by default. Thus if a user comments on your model, it magically gets updated in real time and you can see it without need of any refresh or much delay.
Authentication & User Profiles
Email Verification User Roles: There are currently two kinds of users in OGV, admin and normal. Profile settings: Users can change their name, add a short bio and a profile picture to their profile.

File types supported
Currently OGV supports only .g file as input for uploader, in future it will support more of them.
Model Meta
Each model can have a representative image, that will be shown in model feed. Along with that it can also have a description that can accompany the image. Users can also change name of the model. This editing option is visible to user immediately after user uploads the model.
Model Feeds
The front page of OGV is named as model feed. It consists of all the model posts. A model posts consists of representative image, model description, comments, lovemeter, model name and info about the user who uploaded it. Clicking on representative image takes user to the model viewer page
File Manager
Every user has a file manager, where he can see and edit his own models.
Model Viewer
Model Viewer is a place where user actually sees his models in 3D. He can pan, rotate, zoom in and out and take a good look at model. Here you can also get embed code for models which then you can use to show models from OGV in your website.
