glBindTextures — bind one or more named textures to a sequence of consecutive texture units
void glBindTextures(
|
GLuint first, |
GLsizei count, | |
const GLuint *textures) ; |
first
Specifies the first texture unit to which a texture is to be bound.
count
Specifies the number of textures to bind.
textures
Specifies the address of an array of names of existing texture objects.
glBindTextures
binds an array of existing texture objects to a specified
number of consecutive texture units. count
specifies the number of texture
objects whose names are stored in the array textures
. That number
of texture names are read from the array and bound to the count
consecutive
texture units starting from first
. The target, or type of texture is
deduced from the texture object and each texture is bound to the corresponding target of the
texture unit. If the name zero appears in the textures
array, any existing binding
to any target of the texture unit is reset and the default texture for that target is bound in
its place. Any non-zero entry in textures
must be the name of an existing
texture object. If textures
is NULL
then it is as
if an appropriately sized array containing only zeros had been specified.
With the exception that the active texture selector maintains its current value,
glBindTextures
is equivalent to the following pseudo code:
for (i = 0; i < count; i++) { GLuint texture; if (textures == NULL) { texture = 0; } else { texture = textures[i]; } glActiveTexture(GL_TEXTURE0 + first + i); if (texture != 0) { GLenum target = /* target of textures[i] */; glBindTexture(target, textures[i]); } else { for (target in all supported targets) { glBindTexture(target, 0); } } }
Each entry in textures
will be checked individually and if found
to be invalid, the state for that texture unit will not be changed and an error will be
generated. However, the state for other texture units referenced by the command will still
be updated.
glBindTextures
is available only if the GL version is 4.4 or higher.
Note that because glBindTextures
cannot create new textures (even if
a name passed has been previously generated by call to glGenTextures),
names passed to glBindTextures
must have been bound at least once previously
via a call to glBindTexture.
GL_INVALID_OPERATION
is generated if first
+ count
is greater
than the number of texture image units supported by the implementation.
GL_INVALID_OPERATION
is generated if any value in textures is
not zero or the name of an existing texture object.
