Here it is the patch for windows. As we said in the previous post the implementation is based on the library libcitygml. 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  to install in linux):
- Download the file for your Operating System from.
- Make sure you have installed gvSIG-1.11 and the final release of 3D extension.
- Unzip the patch into a temporal directory.
- Copy bin directory into your gvSIG installation directory, usually located at: C:\Program Files\gvSIG_1.X.X\
- 3) Copy the content of Java directory into your current Java VM directory:
- Run gvSIG 1.11 and follow the videotutorial
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.
