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 one of GL_TEXTURE_1D, GL_TEXTURE_2D,
GL_TEXTURE_3D, GL_TEXTURE_1D_ARRAY, GL_TEXTURE_2D_ARRAY, GL_TEXTURE_RECTANGLE, GL_TEXTURE_CUBE_MAP,
GL_TEXTURE_CUBE_MAP_ARRAY, GL_TEXTURE_BUFFER, 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, GL_TEXTURE_1D_ARRAY, GL_TEXTURE_2D_ARRAY,
GL_TEXTURE_RECTANGLE, GL_TEXTURE_CUBE_MAP, GL_TEXTURE_CUBE_MAP_ARRAY, GL_TEXTURE_BUFFER,
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 array 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_CUBE_MAP_ARRAY becomes a cube-mapped array texture, a texture first bound to
GL_TEXTURE_BUFFER becomes a buffer 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.

GL_TEXTURE_BINDING_BUFFER, GL_TEXTURE_BINDING_CUBE_MAP, GL_TEXTURE_BINDING_CUBE_MAP,
GL_TEXTURE_BINDING_CUBE_MAP_ARRAY, GL_TEXTURE_BINDING_2D_MULTISAMPLE, or
GL_TEXTURE_BINDING_2D_MULTISAMPLE_ARRAY.
