Hello I have several SVG images which I want to use as textures in my application which uses both Qt and OpenSceneGraph. I want to do it using QSvgRenderer on QGLFramebufferObject. It allows to render SVG image directly on FBO and then use rendered image as texture like this:
QGLFramebufferObject * fbo = new QGLFramebufferObject(width, height);
QSvgRenderer renderer(QString("texture.svg"));
QPainter painter(fbo);
renderer.render(&painter);
After that I can use fbo->texture() to get OpenGL texture id and everything
works perfectly in a simple test project (Qt + raw OpenGL). However I can't
find any way to use this texture id with existing OSG classes.
I've googled for the ability to use existing OpenGL textures with OSG and
looked breifly through the code of the osg::Texture and osg::Texture2D and it
looks like I have to create a class derived from the osg::Texture which will
wrap external texture. Is it the right way? Are there any good articles how to
create your own texture class?
