osg::TextureRectangle::TextureRectangle  ) 
 

osg::TextureRectangle::TextureRectangle Image image  ) 
 

osg::TextureRectangle::TextureRectangle const TextureRectangle text,
const CopyOp copyop = CopyOp::SHALLOW_COPY

Member Function Documentation

virtual void osg::TextureRectangle::apply State state  )  const [virtual]
 

On first apply (unless already compiled), create and bind the texture, subsequent apply will simply bind to texture.

Implements osg::Texture.

void osg::TextureRectangle::applyTexImage_load GLenum  target,
Image image,
State state,
GLsizei &  inwidth,
GLsizei &  inheight
const [protected]
 

void osg::TextureRectangle::applyTexImage_subload GLenum  target,
Image image,
State state,
GLsizei &  inwidth,
GLsizei &  inheight,
GLint &  inInternalFormat
const [protected]
 

void osg::TextureRectangle::applyTexParameters GLenum  target,
State state
const [protected]
 

Helper method. Sets texture paramters.

Reimplemented from osg::Texture.

virtual int osg::TextureRectangle::compare const StateAttribute rhs  )  const [virtual]
 

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

Implements osg::StateAttribute.

virtual void osg::TextureRectangle::computeInternalFormat  )  const [protected, virtual]
 

Implements osg::Texture.

void osg::TextureRectangle::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::TextureRectangle::copyTexSubImage2D State state,
int  xoffset,
int  yoffset,
int  x,
int  y,
int  width,
int  height
 

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.

virtual const Image* osg::TextureRectangle::getImage unsigned int   )  const [inline, virtual]
 

Get the const texture image, ignoring face value as there is only one image.

Implements osg::Texture.

virtual Image* osg::TextureRectangle::getImage unsigned int   )  [inline, virtual]
 

Get the texture image, ignoring face value as there is only one image.

Implements osg::Texture.

const Image* osg::TextureRectangle::getImage  )  const [inline]
 

Get the const texture image.

Image* osg::TextureRectangle::getImage  )  [inline]
 

Get the texture image.

unsigned int& osg::TextureRectangle::getModifiedCount unsigned int  contextID  )  const [inline]
 

virtual unsigned int osg::TextureRectangle::getNumImages  )  const [inline, virtual]
 

Get the number of images that can be assigned to the Texture.

Implements osg::Texture.

SubloadCallback* osg::TextureRectangle::getSubloadCallback  )  [inline]
 

virtual int osg::TextureRectangle::getTextureDepth  )  const [inline, virtual]
 

Reimplemented from osg::Texture.

virtual int osg::TextureRectangle::getTextureHeight  )  const [inline, virtual]
 

Reimplemented from osg::Texture.

virtual GLenum osg::TextureRectangle::getTextureTarget  )  const [inline, virtual]
 

Implements osg::Texture.

virtual int osg::TextureRectangle::getTextureWidth  )  const [inline, virtual]
 

Reimplemented from osg::Texture.

osg::TextureRectangle::META_StateAttribute osg  ,
TextureRectangle  ,
TEXTURE 
 

virtual void osg::TextureRectangle::setImage unsigned int  ,
Image image
[inline, virtual]
 

Set the texture image, ignoring face value as there is only one image.

Implements osg::Texture.

void osg::TextureRectangle::setImage Image image  ) 
 

Set the texture image.

void osg::TextureRectangle::setSubloadCallback SubloadCallback cb  )  [inline]
 

void osg::TextureRectangle::setTextureHeight int  height  )  [inline]
 

void osg::TextureRectangle::setTextureSize int  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.

void osg::TextureRectangle::setTextureWidth int  width  )  [inline]
