GLBINDTEXTURE(3G)                                OpenGL 3.3                                GLBINDTEXTURE(3G)



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, or GL_TEXTURE_1D_ARRAY, GL_TEXTURE_2D_ARRAY, GL_TEXTURE_RECTANGLE,
           GL_TEXTURE_CUBE_MAP, GL_TEXTURE_2D_MULTISAMPLE or GL_TEXTURE_2D_MULTISAMPLE_ARRAY.

       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, or GL_TEXTURE_1D_ARRAY, GL_TEXTURE_2D_ARRAY,
       GL_TEXTURE_RECTANGLE, GL_TEXTURE_CUBE_MAP, GL_TEXTURE_2D_MULTISAMPLE or
       GL_TEXTURE_2D_MULTISAMPLE_ARRAY and texture set to the name of the new texture 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 represent the default texture for
       each texture target. Texture names and the corresponding texture contents are local to the shared
       object space of the current GL rendering context; two rendering contexts share texture names only if
       they explicitly enable sharing between contexts through the appropriate GL windows interfaces
       functions.

       You must use glGenTextures() to generate a set of new texture names.

       When a texture is first bound, it assumes the specified target: A texture first bound to
       GL_TEXTURE_1D becomes one-dimensional texture, a texture first bound to GL_TEXTURE_2D becomes
       two-dimensional texture, a texture first bound to GL_TEXTURE_3D becomes three-dimensional texture, a
       texture first bound to GL_TEXTURE_1D_ARRAY becomes one-dimensional array texture, a texture first
       bound to GL_TEXTURE_2D_ARRAY becomes two-dimensional arary texture, a texture first bound to
       GL_TEXTURE_RECTANGLE becomes rectangle texture, a, texture first bound to GL_TEXTURE_CUBE_MAP becomes
       a cube-mapped texture, a texture first bound to GL_TEXTURE_2D_MULTISAMPLE becomes a two-dimensional
       multisampled texture, and a texture first bound to GL_TEXTURE_2D_MULTISAMPLE_ARRAY becomes a
       two-dimensional multisampled array 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 the other texture types.

       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. 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 texture is deleted with glDeleteTextures().

       Once created, a named texture may be re-bound to its same original target 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(), glTexImage3D()
       or another similar function.

NOTES
       The GL_TEXTURE_2D_MULTISAMPLE and GL_TEXTURE_2D_MULTISAMPLE_ARRAY targets are available only if the
       GL version is 3.2 or higher.

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


       GL_INVALID_VALUE is generated if target is not a name returned from a previous call to
       glGenTextures().


       GL_INVALID_OPERATION is generated if texture was previously created with a target that doesn't match
       that of target.

ASSOCIATED GETS
       glGet() with argument GL_TEXTURE_BINDING_1D, GL_TEXTURE_BINDING_2D, GL_TEXTURE_BINDING_3D,
       GL_TEXTURE_BINDING_1D_ARRAY, GL_TEXTURE_BINDING_2D_ARRAY, GL_TEXTURE_BINDING_RECTANGLE,
       GL_TEXTURE_BINDING_2D_MULTISAMPLE, or GL_TEXTURE_BINDING_2D_MULTISAMPLE_ARRAY.
