Detailed Description

Encapsulates OpenGL 1D texture functionality.

Doesn't support cube maps, so ignore face parameters.

Member Function Documentation

void osg::Texture1D::allocateMipmap ( State state) const
protectedvirtual

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

Implements osg::Texture.

virtual void osg::Texture1D::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.

void osg::Texture1D::applyTexImage1D ( GLenum  target,
Image image,
State state,
GLsizei &  width,
GLsizei &  numMipmapLevels 
) const
protected

Helper method.

Create the texture without setting or using a texture binding.

virtual int osg::Texture1D::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::Texture1D::computeInternalFormat ( ) const
protectedvirtual

Implements osg::Texture.

void osg::Texture1D::copyTexImage1D ( State state,
int  x,
int  y,
int  width 
)

Copies pixels into a 1D texture image, as per glCopyTexImage1D.

Creates an OpenGL texture object from the current OpenGL background framebuffer contents at position x, y with width width. width must be a power of two.

void osg::Texture1D::copyTexSubImage1D ( State state,
int  xoffset,
int  x,
int  y,
int  width 
)

Copies a one-dimensional texture subimage, as per glCopyTexSubImage1D.

Updates a portion of an existing OpenGL texture object from the current OpenGL background framebuffer contents at position x, y with width width.

Image* osg::Texture1D::getImage ( )
inline

Gets the texture image.

const Image* osg::Texture1D::getImage ( ) const
inline

Gets the const texture image.

virtual Image* osg::Texture1D::getImage ( unsigned int  )
inlinevirtual

Gets the texture image, ignoring face.

Implements osg::Texture.

virtual const Image* osg::Texture1D::getImage ( unsigned int  ) const
inlinevirtual

Gets the const texture image, ignoring face.

Implements osg::Texture.

unsigned int& osg::Texture1D::getModifiedCount ( unsigned int  contextID) const
inline
virtual unsigned int osg::Texture1D::getNumImages ( ) const
inlinevirtual

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

Implements osg::Texture.

unsigned int osg::Texture1D::getNumMipmapLevels ( ) const
inline

Gets the number of mipmap levels created.

void osg::Texture1D::setImage ( Image image)

Sets the texture image.

template<class T >
void osg::Texture1D::setImage ( const ref_ptr< T > &  image)
inline
virtual void osg::Texture1D::setImage ( unsigned int  ,
Image image 
)
inlinevirtual

Sets the texture image, ignoring face.

Implements osg::Texture.

void osg::Texture1D::setNumMipmapLevels ( unsigned int  num) const
inline

Helper function.

Sets the number of mipmap levels created for this texture. Should only be called within an osg::Texture::apply(), or during a custom OpenGL texture load.

void osg::Texture1D::setSubloadCallback ( SubloadCallback cb)
inline
void osg::Texture1D::setTextureWidth ( int  width)
inline

Sets the texture width.

If width is zero, calculate the value from the source image width.

Member Data Documentation

ref_ptr<Image> osg::Texture1D::_image
mutableprotected

It's not ideal that _image is mutable, but it's required since Image::ensureDimensionsArePowerOfTwo() can only be called in a valid OpenGL context, and therefore within Texture::apply, which is const.

ImageModifiedCount osg::Texture1D::_modifiedCount
mutableprotected
GLsizei osg::Texture1D::_numMipmapLevels
mutableprotected

Number of mipmap levels created.

ref_ptr<SubloadCallback> osg::Texture1D::_subloadCallback
protected
GLsizei osg::Texture1D::_textureWidth
mutableprotected

Subloaded images can have different texture and image sizes.
