'''StormEngineC''' is a [[Free and open-source software|free and open-source]] [[3D computer graphics|3D graphics]] library written in [[JavaScript]] that uses various [[HTML5]] features such as [[WebGL]], [[WebCL]], and [[WebSocket]]s. The library provides a way to load objects in the OBJ or [[Collada]] format and adds them to physical simulations.{{Citation needed|date=November 2023}}

== Features ==
The library provides several features to support the creation of physical simulations. These include:
* Real-time visualization of 3D scenes through [[WebGL]]
* Sun and spot lights
* [[Shadow mapping]]
* [[Screen space ambient occlusion|SSAO]]
* Load of objects on .obj format or [[Collada]] (.DAE)
* Physical system integrated through [http://brokstuk.com/jiglibjs2/ JigLib2]
* Keyframe animation
* Option to enable edit menus
* Multiplayer utilities using [[Node.js]]
* [[Path Tracing]] render using the [https://web.archive.org/web/20120510173953/http://webcl.nokiaresearch.com/ WebCL Nokia Extension]
* [[Render farm]] option for path tracing render using Node.js

== Usage ==
The basic source code for initializing a small scene in StormEngineC:

<syntaxhighlight lang="javascript">
<script src="js/StormEngineC/StormEngineC.class.js"></script>
<canvas id="example" width="1024" height="512"></canvas>

<script>
    stormEngineC.createWebGL({'target': 'example',
                              'editMode': true});
        
    var node = stormEngineC.createNode();
    node.loadObj({'objUrl': 'resources/obj/cornellbox.obj'});
</script>
</syntaxhighlight>

== History ==
StormEngineC was developed to display 3D scenes in the [[web browser]] and to enable a physical system with [[gravity]] and collisions for objects.

It appeared in the first public specification of [[WebGL]], written in [[Java (programming language)|Java]] and called StormEngineJ. It was later ported to JavaScript which benefitted other 3D visualization methods in a web browser. For example, JavaScript does not require extra plug-ins for viewing.

The first version of the library was published on [[Google Code]] in February 2011. At the moment, there has not been offered a stable version of this.

Version 1.2 introduced a rendering system based on [[path tracing]] and optionally can be used as [[render farm]], as well as some facilities for starting up a game server using [[Node.js]].
