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 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_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.
