glFramebufferTextureLayer — attach a single layer of a texture to a framebuffer
void glFramebufferTextureLayer( | GLenum target, |
GLenum attachment, | |
GLuint texture, | |
GLint level, | |
GLint layer) ; |
target
Specifies the framebuffer target. target
must be GL_DRAW_FRAMEBUFFER
, GL_READ_FRAMEBUFFER
, or GL_FRAMEBUFFER
. GL_FRAMEBUFFER
is equivalent to GL_DRAW_FRAMEBUFFER
.
attachment
Specifies the attachment point of the framebuffer. attachment
must be GL_COLOR_ATTACHMENT
i, GL_DEPTH_ATTACHMENT
, GL_STENCIL_ATTACHMENT
or GL_DEPTH_STENCIL_ATTACHMENT
.
texture
Specifies the texture object to attach to the framebuffer attachment point named by attachment
.
level
Specifies the mipmap level of texture
to attach.
layer
Specifies the layer of texture
to attach.
glFramebufferTextureLayer
operates like glFramebufferTexture2D, except that only a single layer of the texture level, given by layer
, is attached to the attachment point. If texture
is not zero, layer
must be greater than or equal to zero. texture
must either be zero or the name of an existing three-dimensional texture, or a two-dimensional array texture.
If texture
is a 3D texture, then level
must be greater than or equal to zero and less than or equal to log2 of the value of GL_MAX_3D_TEXTURE_SIZE
. If texture
is a 2D array texture, level
must be greater than or equal to zero and no larger than log2 of the value of GL_MAX_TEXTURE_SIZE
.
GL_INVALID_ENUM
is generated if target
is not one of the accepted tokens.
GL_INVALID_ENUM
is generated if attachment
is not one of the accepted tokens.
GL_INVALID_VALUE
is generated if texture
is not zero or the name of an existing texture object.
GL_INVALID_VALUE
is generated if texture
is not zero and layer
is negative.
GL_INVALID_VALUE
is generated if texture
is not zero and layer
is greater than the value of GL_MAX_3D_TEXTURE_SIZE
minus one for a 3D texture or greater than the value of GL_MAX_ARRAY_TEXTURE_LAYERS
minus one for a 2D array texture.
GL_INVALID_OPERATION
is generated if zero is bound to target
.
GL_INVALID_OPERATION
is generated if texture
is not zero or the name of an existing three-dimensional texture, or a two-dimensional array texture.
