Hi Aurelien,
I'm also using FBO and mipmaps and I would like to know if you're solved your
problem. I'm assuming FBO doesn't generate mipmap automatically as described is
this document http://www.songho.ca/opengl/gl_fbo.html.
So I created a drawcallback to my render-to-texture geometry and add this code:
Code:
struct DrawCallback : public osg::Drawable::DrawCallback
{
DrawCallback(osg::Texture* texture)
: osg::Drawable::DrawCallback()
, _texture(texture)
{}
~DrawCallback()
{}
void drawImplementation(osg::RenderInfo& ri,const osg::Drawable* dr) const
{
dr->drawImplementation(ri);
osg::FBOExtensions* fbo_ext =
osg::FBOExtensions::instance(ri.getContextID(),true);
ri.getState()->setActiveTextureUnit(0);
ri.getState()->applyTextureAttribute(0, _texture.get());
fbo_ext->glGenerateMipmapEXT(_texture->getTextureTarget());
}
osg::ref_ptr<osg::Texture> _texture;
};
I'm not sure about the final result as I've still some bugs. So I'm very
interesting by your solution.
Regards,
Kenzo
