  1. Display of markers, polygons and polylines (KML)

    Would be interesting to have the possibility to load KML data and display markes, polygons, polylines on the globe

    • Display terrain (elevation, geometric height, DTM): mountains, etc.

      Visualize 3D terrain instead of the sphere only.

      Note: this involves preparing and hosting of a separate tileset which will represent the geometric height by the values of pixels (greyscale). Triangles in the WebGL Earth can be then adjusted by the relevant height (pixel value) loaded from the texture (tile) at given lat/lon position.

      Possible datasets to use:
      - GTOPO30: global digital elevation model (DEM) ~ 1km x 1km - http://eros.usgs.gov/#/Find_Data/Products_and_Data_Available/gtopo30_info
      - SRTM3: Shuttle Radar Topography Mission ~ 90m x 90m - http://www2.jpl.nasa.gov/srtm/
      - CGIAR: 90m

        • Reduce CPU usage

          This demo consumes app. 50 % of CPU cyles on an Athlon 2.8 GHz machine. Thats a lot!

          • Buildings, Collada models

            Display houses and buildings available in the Collada format.

            Notes:
            More efficient then direct support for Collada format would be to convert the models in advance into JSON files:
            http://code.google.com/p/o3d/wiki/ColladaConverter
            http://code.google.com/p/opencollada/

            Follow: http://learningwebgl.com/blog/?p=1658

            The initial implementation should probably load the model and locate it in a correct place on Earth programmatically.

            For efficient displaying of whole town composed of larger amount of models a server side preprocessing or dynamic streaming must be implemented - with several level of details (generalized version of model for distant view, detailed for close view once it is loaded).

            I we need something like: http://www.youtube.com/watch?v=rGLInTXTdNI#t=07s

                • Use some defaukt texture to avoid transparent holes at the top and bottom of planet

                  At the momet WebGL model have an annoying hole ath the top and bottom and also a stripe without a texture.

                  I suppose, it would be nice to use some generic texture for this problem places

                      Google Maps street view already supports WebGL including 45 degrees view, 3d view, terrain,etc. as an opt. in feature. I would like to be able to see street view and Google maps when using pull down list options. Also, see what you can do with Google Earth.

                        Scroll should rotate the globe while two keyboard keys should zoom in/out

                          • i have some workarounds for a better look of the planet...

                            You could try using a scalable mask to avoid people to see the polygons in full view.
                            I probably have a workaround for the pole polygons i don't see right now.

                            i made a similar work under flash with no zoom, for a site about mars terraformation
                            and if you want ask me for ideas and code
                            i'll be glad to participate

                                  • How can I display tiles which are diffrent matrix on globe?

                                    Hello
                                    I meet such a problem. My tiles projection is not different from regular,
                                    which I mean for example WebGLEarth tiles matrix is square(such as 4x4,8x8
                                    etc), but our projection is different as the tiles matrix is rectangle
                                    (such as 4x2,8x4 etc).
                                    our Y axis is half smaller than the regular Y axis.
                                    who can help you about this problem?thank you very much
