glFramebufferTextureLayer: attach a single layer of a texture to a framebuffer

Function Definition

 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_ATTACHMENTi, GL_DEPTH_ATTACHMENT​, GL_STENCIL_ATTACHMENT​ or GL_DEPTH_STENCIL_ATTACHMMENT​.
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.

Description

glFramebufferTextureLayer operates like glFramebufferTexture, 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, one- or two-dimensional array texture, or multisample array texture.

Errors

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_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 cube map texture.
