[Gvsig_english] View3D

[Neumann, Tobias]

Hi Jordi,
 
you are great, thank you! I have reiszed the picture and it works! In the next days I will spend some time with the data access.
 
Regards
Tobias

Hi Tobias, 

The size of the texture you are trying to see exceeds the capabilities of graphic cards 2D textures (4096x4096). If you read carefully the documentation you will realize that osgVP don't tile your images, you have to implement your own data driver to accomplish this task. We utilize de gvSIG data access in order to request the tiles for a image, so it is done at the application level. At the end, osgVP is waiting tiles (usually 256x256 or 512x512 ), not big images, as the data access is not implemented in osgVP. 

Try to use a smaller texture, like in the osgVP examples framework, to test it works, and then you should think about implementing your own driver or use data access from third-party applications. 

Hope it helps. 

Greetings. 

 

 In the osgVP framework there are some examples of loading raster layers using 512x512 tiles.

	Dear Jordi,
	
	I have got a problem with displaying some geodata into the TerrainViewer.
	
	I have successfully build the example with the cow at the north pole (I have send a screenshot of it), but when I want to load a satellite footprint as texture (chapter "Adding layers") it will not be displayed.
	
	When the update-method is called (public UpdateDataEvent loadData(RequestDataEvent rde)) the log output is like "Scaling image 'C:\...\World1_24M.jpg' from (7200,3600) to (8192,4096)", but I can only see the grey plane surface of the default terrain.
	
	I have created the RasterLayer and added it to a new LayerManager. This LayerManager then is getting assigned as the LayerManager of my earth-terrain (just new Terrain()).
	
	Do you have an easy explanation for this problem?
	
	Thank you
	Tobias

	Hi Tobias,
	
	The code you are looking for must utilize osgVirtualPlanets (osgVP). The documentation is available here[1], take a look to the Terrain Section. You will find simple snippets of code to achieve this kind of things. Hope it helps.
	
	Cheers.

	       Hi,
	
	       I am trying to set up a 3D view with gvSIG. Does someone have got a short code example how to generate and display a default spherical view?
	
	       Thank you!
	
	       Tobias
