static osg::Texture* makVrv::DtOsgImageUtils::createTexture ( osg::Image *  image )

static

Creates a texture from an osg::Image.

If the image has one layer (r==1) the method creates an osg::Texture2D. If the image has more than one layer (r>1) the method creates an osg::Texture2DArray.

static bool makVrv::DtOsgImageUtils::flattenImage ( osg::Image *  input, std::vector< osg::ref_ptr< osg::Image > > &  output  )

static

Converts a multi-layer image (r>1) into a vector of single-layer images.

static void makVrv::DtOsgImageUtils::configureTextureForAutoReload ( osg::Texture *  texture )

static

Configures a Texture to automatically reload its image data from the original source upon demand.

By default if you set a texture to unref its image data after GL apply, that will save memory but prevent the texture from working in a future and different GL context. Call this to get the benefits of both.
