Here's how I scale down a texture, in my case it gets applied to
a height-field:
float scale = 0.1;
osg::TexMat* texmat = new osg::TexMat;
osg::StateSet* set = meshGeom->getOrCreateStateSet();
set->setTextureAttributeAndModes(0, texmat,
osg::StateAttribute::ON);
Cheers

Hi Ulrich,
Please give me a hint (a line of code) how to set the texture matrix. As
I am new to osg, I would appreciate this a lot.
Regards
Christian

Dear osg-users,
I want to create a floor textured with a small image being repeated.
Thats what I am doing, but the texture is stretched (i.e shown only
once). What is wrong? I am using the latest OSG version from SVN.
ShapeDrawable doesn't support repeating of texture coordinates. The
closest you could get is to use osg::TexMat, but in the end I think
it'd be easier just to create the geometry yourslef as you need it.
To elaborate on that a bit, ShapeDrawable creates texture coordinates
only in the range of 0.0 to 1.0 i.e. the lower-left of the texture in
one corner (of your cube) and the upper-right of the texture in the
opposite corner.
If you place a texture matrix using scale 1000,1000,1 it should look
as you expect.
Cheers,
