Hi John
Hi,
Everyone, this is my first post. I have quick question for you guys, this might
be a simple one but I am still new with OSG.
I am building a map scene with 3D Max and exporting it with OpenSceneGraph Max
Exporter however I noticed the OSG Viewever doesn't support textures larger
than 8000 x 8000. If I want to have a larger texture on the terrain it just
downsamples that to 8000 pixels.
Is this an OSG limitation or an OSG Viewever one? Can I somehow support larger
textures? All I am trying to do is to create a simulation of my local town, and
I would need a large area covered with texture from google maps so the ground
doesn't look ugly from the top. Is there a way around it ?
I guess the actual limitation is 8192x8192 as it is the limit on most
GPU for textures. There are some higher-end GPUs supporting 16384x16384
pixels.
This has nothing to do with IVE. You can also check it with osgViewer
--image %filename% to test without any model involved.
First of all, if you're planning to use big geospecific databases you
can use VirtualPlanetBuilder or osgEarth which do the job of correctly
referencing, projecting and tiling your dataset efficiently.
Usually if you want to cover bigger areas with textures you would simply
split them into chunks and map them to the geometry.

Thank you for your help! Much appreciated!
Cheers,
John
