openwebglobe / webviewer Goto Github PK

All three billboard examples don't seem to work, or at least I couldn't find the billboard.

Hello
I'm new so... escuse my question if its trivial.
I am testing Openglobe, and it works fine with local OSM generated tiles without a server, but once I try to do the same with owg generated elevation tiles, I cant it make work. I need to put all stuff in a server...
Cant json files be read from a directory in within the main app as the image tiles? I want to make a little stand alone app without a server...
Thank you in advance

Hi,
I will design the Virtual Globe for 3D cadastre by OpenWebGlobefor MSc thesis, I need to understand and know about OpenWebGlobe features and functions.
Please help me. For visualization 3D cadastre we need a many features. Please tell me by "Yes or No" about blew features that exist in OpenWebGlobe?
Thanks a lot. It is very necessary.

Cadastral features/

Handling massive data?:
Result of functions and queries:
Underground view:
Cross-section view:
Measurements (3D)(distance, 3D buffer and etc):
Non-spatial data visualization(attribute):

Visualization features/
Interactivity(zooming, model view,indoor building view):
Levels of detail:
Symbols:
Color, thickness, line-style:
Labeling:
Transparency:
Tooltips:

Non-functional features/
Technical diversity:
System integration and
interoperability:
Usability:
Platform independence:
Cost:
Web-based 3D visualization:

Other features/
Profiling:
Shadow analysis:
Animation creation:
Line of sight and visibility analysis:
Skyline creation:
Texture mapping:
Aerial and satellite images:
3D updating and manipulating:

Thanks so much,

Best Regards,
Sabah Motamedi

It would be great, if a feature like https://github.com/kekscom/osmbuildings could be integrated a layertype in OpenWebGlobe.

The implementation of OSM Buildings looks like:

1. Fetch the buildings 2d footprints and height of twice the current map extent from a database
2. Extrapolate the 2d poylgon to a 3d shape. Triangulation and mesh creation should happen automatically.
3. Render the resulting shapes.

I really think this could be useful for OpenWebGlobe, because most building data is footprints of buildings including height.

The resulting mechanism could easly be extended to support texturing of buildings (specify a texture for every wall and one for the roof).

The current possibilities of importing of json files for buildings are IMHO too static for larger sets of buildings.

I use dataprocessing tool to generate image layer, the border of the image tiled has black data, using webviewer to display the image layer will display the black data, how to erase black data?

Now I know the way to set Point-Color ,
But how to set color to each face ?

Here's the Geometry-JSON , can anyone tell me how to change the json to fit Face-Color ?

Thank you.

Hi,

I have compiled everything with no errors and tested the demo in source\demos\99_Minimal.
If I use debug.html all is ok; when i use index.html i get the error

Uncaught Error: SECURITY_ERR: DOM Exception 18

on Chrome 14.0.835.186

and

Security error

on Firefox 8.0

Thanks,
Vito

None of the demos work due to the requirement of pre-installing the google closure library

These script tags are the items that point to these items.

src="../../../external/closure-library/closure/goog/base.js"
src="../../../compiled/deps.js"
goog.require 'owg.OpenWebGlobe'

Must we compile everything?

/jpr

when i zoom in the layer to maxlod, the owg will display a blue rectangle. How to solve it?

Hi,

I'm trying to create a scene with OG_SCENE_3D_FLAT_CARTESIAN.
When I run the following minimal code from a demo directory, ogCamera complains about a missing navigation node. Am I missing something or is 3D Flat not supported yet?

Thanks,
Hannes

Can anybody tell me how to compile webviewer with the closure library.
I am new to both openwebglobe and closure library and wants to give it a try..
I have webGL enabled in my browser.

I can set color and transparency to each point ,
but how to set color to each face ?

I have compiled everything with no errors and now i am getting a poiloader.js not found error when i try to run demo.html. I also get a security violation (18) when i try to run the source/tutorials/05_POI/POI_06_Test.html file.

The security violation is weird because i am running from a local server on port :8090. I will check if cookies are disabled, but i doubt that is true since in have been using this server for a long time.

Hi

Most 3D apps uses middle (wheel) click for changing altitude/azimuth. It appears you rely on right click.
Won't it be more user-friendly to stay with the "middle" standard ?

It could also free the right click for a contextual menu.

(Maybe there's a technical limitation ?)

Hi all,
I just want to tell about my experience with this library. I was working on an acheological site located near seaside. The first problem i encountered is the height, i shoul hack the minimum height to look at the buildings below 50 meters (at 10 meters). That worked fine, but it was the version (release) downloaded in november 2012.
The last vesion, i tried from trunk in the first months of the 2013 had the tremendous side-effect of cutting land when camera is close to terrain level. So when camera is close to terrain there's some kind of fake section of the earth.

Hope this could be easily fixed

Thanks

I use GeoServer publish a wms service, but openwebglobe can not display it. why not? The firefox bug network displays the wms service call correctly.
