glRenderbufferStorage — establish data storage, format and dimensions of a renderbuffer object's image
void glRenderbufferStorage( | GLenum target, |
GLenum internalformat, | |
GLsizei width, | |
GLsizei height) ; |
target
Specifies a binding to which the target of the allocation and must be GL_RENDERBUFFER
.
internalformat
Specifies the internal format to use for the renderbuffer object's image.
width
Specifies the width of the renderbuffer, in pixels.
height
Specifies the height of the renderbuffer, in pixels.
glRenderbufferStorage
is equivalent to calling
glRenderbufferStorageMultisample with the
samples
set to zero.
The target of the operation, specified by target
must be GL_RENDERBUFFER
.
internalformat
specifies the internal format to be used for the renderbuffer object's storage and
must be a color-renderable, depth-renderable, or stencil-renderable format.
width
and height
are the dimensions, in pixels, of the renderbuffer.
Both width
and height
must be less than or equal to the value of
GL_MAX_RENDERBUFFER_SIZE
.
Upon success, glRenderbufferStorage
deletes any existing data store for the renderbuffer
image and the contents of the data store after calling glRenderbufferStorage
are undefined.
GL_INVALID_ENUM
is generated if target
is not GL_RENDERBUFFER
.
GL_INVALID_VALUE
is generated if either of width
or height
is negative,
or greater than the value of GL_MAX_RENDERBUFFER_SIZE
.
GL_INVALID_ENUM
is generated if internalformat
is not a color-renderable, depth-renderable,
or stencil-renderable format.
GL_OUT_OF_MEMORY
is generated if the GL is unable to create a data store of the requested size.
