Detailed Description

Texture2DMultisample state class which encapsulates OpenGL 2D multisampled texture functionality.

Multisampled texture were introduced with OpenGL 3.1 and extension GL_ARB_texture_multisample. See http://www.opengl.org/registry/specs/ARB/texture_multisample.txt for more info.

(

State &

state

)

const [inline, virtual]

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

Implements osg::Texture.

(

const StateAttribute &

rhs

)

const [virtual]

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

Implements osg::StateAttribute.

(

)

const [protected, virtual]

Implements osg::Texture.

virtual Image* osg::Texture2DMultisample::getImage

(

unsigned

face

)

[inline, virtual]

Gets the texture image for the specified face.

Implements osg::Texture.

References NULL.

virtual const Image* osg::Texture2DMultisample::getImage

(

unsigned

face

)

const [inline, virtual]

Gets the const texture image for specified face.

Implements osg::Texture.

References NULL.
