AI2 3D Viz group capabilities

Hi all,

Here we are after the 7th International gvSIG Conference. We were glad to see the interest demonstrated by the audience to our seminar.

We are very grateful to the project España Virtual, Prodevelop, CNIG and the gvSIG association for their support so far. But now the ai2 team is in trouble due to the lack of funding. As you probably know, the downturn has a very negative impact on R&D teams. We want to continue developing gvSIG 3D, osgVirtualPlanets and any new challenges proposed.
 
The following video shows the capabilities of our team. Some of the features showcased in the video have been developed in the scope of gvSIG 3D. Others are prototypes or research projects we are working on. Our expertise is in 3D GIS visualization for desktop and mobile environments, also in OpenSceneGraph. So if you are interested in contributing in any manner contact us.

Enjoy the video and switch on your speakers!

Animation video tutorial

Hi all!

This time we want to share a contribution from Mario Carrera, from the gvSIG team. It explains how to make an animation with the animation extension. He is kindly explaining 3D extension on meetings and conferences where we are not able to be. Thanks for that too Mario :) . 

As you know, we are near the 7th International gvSIG Conference and the ai2 team will be there talking about 3D extension. We will post soon about the contents here and in the gvSIG Blog.

Check the gvSIG videos section and the gvSIG3D youtube channel  for more tutorials!

cityGML patch for windows

Hi again!

Here it is the patch for windows. As we said in the previous post the implementation is based on the library libcitygml[1]. This open source project is still in development and we'd like to thank to Joachim Pouderoux (the main developer) for his kindly help. 

The work is in progress, but we think it is a good moment to let the community to test this new feature. The patch is now available for linux and windows. The instructions to install it in windows are the following -also available in a README.txt file- (see [2] to install in linux):

1. Download the file for your Operating System from[3]. 
2. Make sure you have installed gvSIG-1.11[4] and the final release of 3D extension[5].   
3. Unzip the patch into a temporal directory.
4. Copy bin directory into your gvSIG installation directory,  usually located at: C:\Program Files\gvSIG_1.X.X\
5. 3) Copy the content of Java directory into your current Java VM directory: 
   C:\Program Files\Java\jre1.6.0.X\
   
6. Run gvSIG 1.11 and follow the videotutorial[2]

Important note: If you have different Java VM installed in your system 
you can check if the folder jre1.X.X/bin has a subfolder called osgPlugins-2.8.3 
to check the correct version (the one used by gvSIG and the 3D extension). 
In addition, some windows systems need administrator privileges to overwrite this files.

Patch to load cityGML models in gvSIG 1.11 + 3D extension

Hi community!

We are working again after a great holydays. This time we want to share with you our advances in the scope of the Project "España Virtual". For this reason we have done a backport for gvSIG 1.11 of a new feature we are working on: to load cityGML models.

The implementation is based on the library libcitygml[1]. This open source project is still in development and we'd like to thank to Joachim Pouderoux (the main developer) for his kindly help. 

The work is in progress, but we think it is a good moment to let the community to test this new feature. The patch is only available for linux (we expect to upload the patch for windows in a few days) and the instructions to install it are very simple:

1. Download the file for your Operating System from[2]. 
2. Make sure you have installed gvSIG-1.11[3] and the final release of 3D extension[4].  
   
3. Extract the compressed file in the folder you installed gvSIG-1.11, overwriting the folders bin and libs.
   
4. Run gvSIG 1.11 and follow the next video tutorial! :)
   

Important note: cityGML files must be renamed as .citygml, otherwise the osg loader won't be able to load the models.

WIP: 3D extension on gvSIG 2.0

Hi all!

Just before the gvSIG 3D team goes away on vacations, we'd like to show you a sample of one line of work that has been in development for the last few months. Since the release of gvSIG 2.0 is getting closer, we decided to start the process of adapting gvSIG 3D to this new version in the scope of the España Virtual project.

As some of you may know, gvSIG 2.0 is not just an iteration of the 1.x branch, therefore changes have been made to the core of the application that doesn't make the task of porting our extension a trivial job.

In this post we would like to make a little summary of the tasks that have been already finished, and those that are still in development.

Finished tasks:

• Adapted the building system and dependencies.
• Changed the projects architecture to match the gvSIG 2.0 requirements.
• Document View3D available from the Project Manager. Creates and customizes spherical and flat planet views.
• Loading of raster and rasterized vectorial layers.
• Integration of the gvSIG 3D tools. Navigation modes, stereo and fullscreen visualization, etc.

In progress:

• Adapt the extension to work with osgVP 3.0.
• Use the cache system of the new raster libraries.
• Analyze and integrate the new symbology framework from osgVP and gvSIG.
• Modify the persistence mechanism to match the new requirements.
• Integrate the load and edition of OSG layers.

Finally, in the next video, you can see gvSIG 3D running on top of the latest build (2030) of gvSIG 2.0.

Keep in mind that the status of the project is still of early alpha, therefore there isn't a binary distribution to download yet.

Coming soon: PostGIS 3D!!

Hi all,

We are really happy to announce this new feature. A part form being a nice improvement it has something special... it comes from the community!

The author of the patch is Jose Carlos Martinez-LLario from DICGF at UPV. He is very skilled in spatial database development, in fact he owns a very promising project called JASPA. We have to mention Fran Peñarrubia and Nicklas Aven, they helped too in testing and integration of the patch.

So...Thank you very much guys!

The patch is already commited in the trunk of gvSIG 1.1x and it will be available in gvSIG 1.12 version. This patch does not change anything in gvSIG 3D, the changes are applied to the core of gvSIG so the same version of 3D extension (codename "BladeRunner") should work with postGIS 3D.

Next video is a demo of postGIS 3D running in gvSIG 3D. We'll do some tutorial when gvSIG 1.12 becomes available. 

OpenSceneGraph-3.0.0 released!

Hi all!

A new version of OpenSceneGraph (OSG) has been released. OSG is the standard scenegraph for OpenGL Applications and we are using it extensively in our core library OSGVirtualPlanets (osgVP). We are proud to be contributors of OSG, and our last contribution was to add Android support to the library. Next releases of OSGVirtualPlanets will be built against OSG 3.0.0.

From here we'd like to thank the work done by the whole OSG community and specially to Robert Osfield, the leader of the library. 
 
FYI this is the OSG 3.0 Press Release:
