Exporting models as X3D for the web

Entering 3D data in a PostGIS database is not nearly as interesting if we have no capacity for extracting the data back out in some useable form. One way to approach this problem is to leverage the PostGIS ability to write 3D tables to the X3D format.

X3D is an XML standard for displaying 3D data and works well via the web. For those familiar with Virtual Reality Modeling Language (VRML), X3D is the next generation of that.

To view X3D in the browser, a user has the choice of a variety of plugins, or they can leverage JavaScript APIs to enable viewing. We will perform the latter, as it requires no user configuration to work. We will use X3DOM's JavaScript framework to accomplish this. X3DOM is a demonstration of the integration of HTML5 and 3D and uses Web Graphics Library (WebGL); (https://en.wikipedia.org/wiki/WebGL) to allow rendering and interaction with 3D content in the browser. This means that our data will not get displayed in browsers that are not...

Vincent Mather

Vincent Mather

Stephen Vincent Mather has worked in the geospatial industry for 15 years, having always had a flair for geospatial analyses in general, especially those at the intersection of Geography and Ecology. His work in open-source geospatial databases started 5 years ago with PostGIS and he immediately began using PostGIS as an analytic tool, attempting a range of innovative and sometimes bleeding-edge techniques (although he admittedly prefers the cutting edge).

Mastering PostGIS

Mastering PostGIS

PostGIS is an open source spatial database system that offers a wider array of spatial analysis function and representation of geometric data types to databases. This book offers a tailored approach to practice common and most complex geo-processing tasks experts do with ease to design efficient GIS systems. Through the course of the book, not only will you learn what are the different data types, spatial querying, indexing and other complex operations on data, but also learn to create an end to end GIS solution. This book aims to teach you how to get maximum out of PostGIS and integrate it with other platforms like Geoserver, Opelayers, Javascript libraries to create a fully analytical GIS application.
