Hello Stacho, thanks for your answer. Now I reduced the overlay image to 5000x5000 pixel. Still bigger than the 4096 but as I don't know GL_MAX_TEXTURE_SIZE it will be rescaled anyhow. File size is also smaller and it loads significantly faster. The question arose as I have access to a workstation with a quite good grafics card and if it would be possibe to use the full resolution... Anyhow the model looks nice now. I have another strange problem: the model gets loaded without surface texture (only gray height field) when I open the lox file on my external hard disk or from C:\temp. On the "desktop" it shows correct. Any idea? Best regards Wolfgang Am 27.04.2010 13:49, schrieb Stacho Mudrak:
Hi Wolfgang,
texture image size is limited by your hardware (GL_MAX_TEXTURE_SIZE variable returned by OpenGL) or 4096x4096 max. But if your input image is larger, it is scaled down. There is no limit on elevation model, but with some high density, there may be performance problems.
Best regards, S.

Hi,
I once read somewhere that the overlay size is limited. Can anyone tell me where this limit is and where it could be changed (is it hard coded or hidden in a ini-file)? Is there something similar for the elevation model?
Many thanks Wolfgang _______________________________________________ Therion mailing list Therion@speleo.sk http://mailman.speleo.sk/mailman/listinfo/therion
