Detailed Description

Texture2DArray state class which encapsulates OpenGL 2D array texture functionality. Texture arrays were introduced with Shader Model 4.0 hardware.

A 2D texture array does contain textures sharing the same properties (e.g. size, bitdepth,...) in a layered structure. See http://www.opengl.org/registry/specs/EXT/texture_array.txt for more info.

◆ compare()

virtual int osg::Texture2DArray::compare ( const StateAttribute & rhs) const
virtual

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

Implements osg::StateAttribute.

◆ computeInternalFormat()

virtual void osg::Texture2DArray::computeInternalFormat ( ) const
protectedvirtual

void osg::Texture2DArray::copyTexSubImage2DArray ( State & state,
int xoffset,
int yoffset,
int zoffset,
int x,
int y,
int width,
int height )

Copies a two-dimensional texture subimage, as per glCopyTexSubImage3D. 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. zoffset specifies the layer of the texture array to which the result is copied.

◆ getImage() [1/2]

virtual Image * osg::Texture2DArray::getImage ( unsigned int layer)
virtual

Get the texture image for specified layer.

Implements osg::Texture.

◆ getImage() [2/2]

virtual const Image * osg::Texture2DArray::getImage ( unsigned int layer) const
virtual

Get the const texture image for specified layer.

Implements osg::Texture.

◆ getModeUsage()

virtual bool osg::Texture2DArray::getModeUsage ( StateAttribute::ModeUsage & ) const
inlinevirtual

Texture2DArray is related to non fixed pipeline usage only so isn't appropriate to enable/disable.

Reimplemented from osg::StateAttribute.

◆ getModifiedCount()

unsigned int & osg::Texture2DArray::getModifiedCount ( unsigned int layer,
unsigned int contextID ) const
inline

Check how often was a certain layer in the given context modified

References _modifiedCount.

Referenced by isDirty().

◆ getNumImages()

virtual unsigned int osg::Texture2DArray::getNumImages ( ) const
inlinevirtual

Get the number of images that are assigned to the Texture. The number is equal to the texture depth. To get the maximum possible image/layer count, you have to use the extension subclass, since it provides graphic context dependent information.

Implements osg::Texture.
