void osg::TextureCubeMap::allocateMipmap |
( |
State & |
state |
) |
const [protected, virtual] |
Allocate mipmap levels of the texture by subsequent calling of glTexImage* function.
Implements osg::Texture.
virtual void osg::TextureCubeMap::apply |
( |
State & |
state |
) |
const [virtual] |
On first apply (unless already compiled), create the mipmapped texture and bind it. Subsequent apply will simple bind to texture.
Implements osg::Texture.

| | |
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.
static Extensions* osg::TextureCubeMap::getExtensions |
( |
unsigned int |
contextID, |
|
|
bool |
createIfNotInitalized | |
|
) |
| | [static] |
Function to call to get the extension of a specified context. If the Exentsion object for that context has not yet been created and the 'createIfNotInitalized' flag been set to false then returns NULL. If 'createIfNotInitalized' is true then the Extensions object is automatically created. However, in this case the extension object will only be created with the graphics context associated with ContextID.
Reimplemented from osg::Texture.
virtual Image* osg::TextureCubeMap::getImage |
( |
unsigned int |
face |
) |

Get the texture image for specified face.
Implements osg::Texture.

face |
) |
const [virtual] |
Get the const texture image for specified face.

|
) |
| | [static] |
The setExtensions method allows users to override the extensions across graphics contexts. Typically used when you have different extensions supported across graphics pipes but need to ensure that they all use the same low common denominator extensions.
Reimplemented from osg::Texture.
virtual void osg::TextureCubeMap::setImage |
( |
unsigned int |
face, |
|
|
Image * |
image | |
|
) |
| | [virtual] |
Set the texture image for specified face.
Implements osg::Texture.
void osg::TextureCubeMap::setNumMipmapLevels |
( |
unsigned int |
num |
) |
const [inline] |
Set the number of mip map levels the the texture has been created with. Should only be called within an osg::Texuture::apply() and custom OpenGL texture load.

( |
SubloadCallback * |
cb |

[inline] |
void osg::TextureCubeMap::setTextureSize |
( |

width, |
|
|
int |
height | |
|
) |
| | const [inline] |
Set the texture width and height. If width or height are zero then the repsective size value is calculated from the source image sizes.

( |
int |
width |
) |
