With libraries like Cairo available, I'm not sure why you'd need to
write your own. I've written a glue module for Cairo/OSG which lets
you use a vector graphics API on a Texture2D canvas.
For example, the attached image was rendered using Cairo on a small
texture (256x256). No image files were
Hi James,
I believe you have to:
texture-setFilter(osg::Texture2D::MIN_FILTER,osg::Texture2D::NEAREST);
texture-setFilter(osg::Texture2D::MAG_FILTER,osg::Texture2D::NEAREST);

I decided to go down the route of writting my own line, circle etc
algorithms as I only need a few, but I have hit a slight snag. :-( I have
attached an image to show the effect I am getting, ideally I would like the
Texture2D which is projected onto the billboard to be sharper? I.e the lines
Hi,
I was wondering if it is possible to draw on a Texture2D instance. I know
this isn't possible, but I am wondering if you can do the equivalent of:
Texture2Dinstance-DrawCircle(x,y,r);
Or would I have to find an API which can create images and saves to say
JPEGs then load them as Texture2D
Hi James,
Perhaps a Render To Texture Camera is what you are look for. Have a
look at the osgprerender example.

OSG does not do 2D drawing to images. You can do your own by getting the
data pointer from an
Many thanks, that seems to be exactly what I am looking for.
