NAME

       glBindTexture - bind a named texture to a texturing target

C SPECIFICATION

       void glBindTexture( GLenum target,
			   GLuint texture )

PARAMETERS

       target	Specifies the target to which the texture is bound.  Must be either GL_TEXTURE_1D, GL_TEXTURE_2D, or GL_TEXTURE_3D.

       texture	Specifies the name of a texture.

DESCRIPTION

       glBindTexture lets you create or use a named texture. Calling glBindTexture with
       target  set to GL_TEXTURE_1D, GL_TEXTURE_2D, GL_TEXTURE_3D and texture set to the name of the newtexture binds the texture name to the tar-
       get.  When a texture is bound to a target, the previous binding for that target is automatically broken.

       Texture names are unsigned integers. The value zero is reserved to represent the default texture for each texture  target.   Texture  names
       and  the  corresponding texture contents are local to the shared display-list space (see glXCreateContext) of the current GL rendering con-
       text; two rendering contexts share texture names only if they also share display lists.

       You may use glGenTextures to generate a set of new texture names.

       When a texture is first bound, it assumes the dimensionality of its target:  A texture first  bound  to	GL_TEXTURE_1D  becomes	one-dimen-
       sional,	and  a	texture  first bound to GL_TEXTURE_2D becomes two-dimensional, and a texture first bound to GL_TEXTURE_3D becomes a three-
       dimensional texture. The state of a one-dimensional texture immediately after it is first bound is equivalent to the state of  the  default
       GL_TEXTURE_1D at GL initialization, and similarly for two-, and three-dimensional textures.

       While  a texture is bound, GL operations on the target to which it is bound affect the bound texture, and queries of the target to which it
       is bound return state from the bound texture. If texture mapping of the dimensionality of the target to which a texture is bound is active,
       the  bound  texture  is used.  In effect, the texture targets become aliases for the textures currently bound to them, and the texture name
       zero refers to the default textures that were bound to them at initialization.

       A texture binding created with glBindTexture remains active until a different texture is bound to the same target, or until the bound  tex-
       ture is deleted with glDeleteTextures.

       Once  created,  a named texture may be re-bound to the target of the matching dimensionality as often as needed.  It is usually much faster
       to use glBindTexture to bind an existing named texture to one of the texture  targets  than  it	is  to	reload	the  texture  image  using
       glTexImage1D, glTexImage2D, or glTexImage3D.  For additional control over performance, use glPrioritizeTextures.

       glBindTexture is included in display lists.

NOTES

       glBindTexture is available only if the GL version is 1.1 or greater.

ERRORS

       GL_INVALID_ENUM is generated if target is not one of the allowable values.

       GL_INVALID_OPERATION is generated if texture has a dimensionality that doesn't match that of target.

       GL_INVALID_OPERATION is generated if glBindTexture is executed between the execution of glBegin and the corresponding execution of glEnd.
