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

Implements osg::Texture.

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

inlinevirtual

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.

SubloadCallback* osg::Texture1D::getSubloadCallback ( )

inline

const SubloadCallback* osg::Texture1D::getSubloadCallback ( ) const

inline

virtual int osg::Texture1D::getTextureDepth ( ) const

inlinevirtual

Reimplemented from osg::Texture.

virtual int osg::Texture1D::getTextureHeight ( ) const

inlinevirtual

Reimplemented from osg::Texture.

virtual GLenum osg::Texture1D::getTextureTarget ( ) const

inlinevirtual

Implements osg::Texture.

Gets the texture width.

Reimplemented from osg::Texture.

osg::Texture1D::META_StateAttribute	(	osg	,
		Texture1D	,
		TEXTURE
	)

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.
