[x3d-public] Showcase: 3D maps showing sea level change using X3D/X3DOM

[Mike McCann]

Hello Magnus,

This is a very intuitive and informative interactive presentation!

I agree that X3D/X3DOM is a smoother choice, especially when we have limited time and need to do a lot of data preparation.

I notice that you use a single ElevationGrid and can understand why, as it’s simpler to integrate the Sea level adjustment component of your application. 

Just a note regarding dealing with geospatial data: X3DOM also has the Geospatial component – if GeoElevationGrid were used then other data might be more easily added to the scene using latitude, longitude, elevation coordinates, rather than having to first convert to custom coordinates needed for each ElevationGrid.

It took me a week of spare time from completing the first "Hello, X3DOM!" tutorial to having a set of 370 coastal areas around the world in interactive 3D on the web, most of that time required to massage geodata from GEBCO and GeoNames into proper format: http://sealevelrise.se/en/earth_3d1/

Once more, thank you!

I wrote my first 2-pass (light and shadow) 3D renderer back in 1981, in BASIC on a micro-computer with a 2.2 MHz 8 bit Z80-processor and 32 KB RAM, taking 2 weeks to render a 332 face mesh model (608 tris) in high resolution (2304x1152 px). In 1995-1996, I created my first 3D scenes on the web using VRML, and later worked with software like RayDream Studio, POV-Ray, Carrara and Poser. 2007-2008 I went into virtual worlds like Second Life and OpenSimulator, and contributed some code to OpenSimulator. Lately, I've created some 3D web content using WebGL and ThreeJS, and contributed some to the ThreeJS documentation.

I'm happy to see I was wrong and that its offspring X3D is still alive and kicking. While e.g. ThreeJS has its charm for some projects, it's overkill for others, and at least for this project, X3D/X3DOM definitely was a smoother choice.
