===Releases===A cross<!-browser JavaScript tool which will emulate Arius3D's PointStream viewer. It will be able to quickly render a large amount of point cloud data to the <canvas> tag using WebGL.<br />[http://scotland.proximity.on.ca/asalga/releases/0.1.zip XBPS 0.1]<br />[http://scotland.proximity.on.ca/asalga/releases/0.2.zip XBPS 0.2]<br />[http://scotland.proximity.on.ca/asalga/releases/0.3.zip XBPS 0.3]<br />[http://scotland.proximity.on.ca/asalga/releases/0.4.zip XBPS 0.4]<br />XBPS 0.4.5 '''[[http://scotland.proximity.on.ca/asalga/releases/0.4.5.zip Only Lib] | [http://github.com/asalga/XB-PointStream/archives/0.4.5 Full]]'''<br />#########

@param {String} eventName - can XB PointStream provides a framework to simplify the streaming and rendering of point clouds allowing them to be one of the following: "onstart" rendered in a web page without any plug- must occur exactly once - func(parser) "onparse" - must occur one or many times ins. - func(parserWebGL, {"VERTEX":[a JavaScript API based on Open GL ES 2.0 enables the creation of 3D content in the web browser without any plugins. It is currently implemented in release version of Firefox and Chrome and development versions of Safari and Opera.], "COLOR":[ To support the creation of 3D content many web libraries have been written...] However, etcmost of these libraries are based on textured meshes. XB PointStream is different from these other libraries in that it focuses on point clouds.

Current browsers that support WebGL are Firefox 4.0+ and current release of Chrome. Development versions of Safari and Opera also support WebGL. If your video card is really old or does not meet standards, your browser may also have problems supporting WebGL.

Once Essentially the event occurs, object is made up of a mesh of flat triangles and a 2D texture graphic that is applied over the parsermesh to give it its colour and depth. will call However, this is not the associated function and pass only way to represent 3D graphics. Another method for representing 3D graphics is that of a point cloud which is a set of coloured points in 3D space. While a point cloud is usually larger than a textured mesh in terms of amount of data, it provides a level of realism not found in a reference to itselfmesh. The parser needs to pass itself back to the library since the library could be working with many parsers simultaneouslyFurthermore, some 3D scanning equipment such as 3D scanners, LiDAR equipment, medical scanners, and MicroSoft's Kinect all deliver their data as point clouds.
