void osg::Texture2D::allocateMipmap ( State &  state) const
protectedvirtual

Allocate mipmap levels of the texture by subsequent calling of glTexImage* function.

Implements osg::Texture.

virtual void osg::Texture2D::apply ( State &  state) const
virtual

Bind the texture object. If the texture object hasn't already been compiled, create the texture mipmap levels.

Implements osg::Texture.

Reimplemented in osgText::GlyphTexture.

virtual int osg::Texture2D::compare ( const StateAttribute &  rhs) const
virtual

Return -1 if *this < *rhs, 0 if *this==*rhs, 1 if *this>*rhs.

protectedvirtual

Implements osg::Texture.

void osg::Texture2D::copyTexImage2D ( State &  state,
int  x,
int  y,
int  width,
int  height 
)

Copies pixels into a 2D texture image, as per glCopyTexImage2D. Creates an OpenGL texture object from the current OpenGL background framebuffer contents at position x, y with width width and height height. width and height must be a power of two.

void osg::Texture2D::copyTexSubImage2D ( State &  state,
int  xoffset,
int  yoffset,
int  x,
int  y,

Copies a two-dimensional texture subimage, as per glCopyTexSubImage2D. Updates a portion of an existing OpenGL texture object from the current OpenGL background framebuffer contents at position x, y with width width and height height. Loads framebuffer data into the texture using offsets xoffset and yoffset. width and height must be powers of two.
