GLBINDTEXTURE(3gl)					    GLBINDTEXTURE(3gl)

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,  GL_TEXTURE_3D,  GL_TEX‐
		TURE_CUBE_MAP, or GL_DETAIL_TEXTURE_2D_SGIS.

       texture	Specifies the name of a texture.

DESCRIPTION
       glBindTexture  lets  you create or use a named texture. Calling glBind‐
       Texture with
       target set to GL_TEXTURE_1D, GL_TEXTURE_2D, or GL_TEXTURE_CUBE_MAP  and
       texture set to the name of the newtexture binds the texture name to the
       target.	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 rep‐
       resent 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	 context;  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 1-dimensional
       and a texture first bound to GL_TEXTURE_2D becomes  2-dimensional.  The
       state of a 1-dimensional texture immediately after it is first bound is
       equivalent to the state of the default GL_TEXTURE_1D at GL  initializa‐
       tion, and similarly for 2-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 initializa‐
       tion.

       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 glTexIm‐
       age1D or glTexImage2D.  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 val‐
       ues.

       GL_INVALID_OPERATION is generated if texture has a dimensionality which
       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.

       GL_INVALID_VALUE is generated if	 target	 is  GL_DETAIL_TEXTURE_2D_SGIS
       and  texture is not the name of a detail texture, the name of an as yet
       unbound texture, or zero.
