NAME¶
glRenderbufferStorage - establish data storage, format and dimensions of a
renderbuffer object's image
C SPECIFICATION¶
void
glRenderbufferStorage(GLenum target,
GLenum internalformat, GLsizei width,
GLsizei height);
PARAMETERS¶
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.
DESCRIPTION¶
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.
ERRORS¶
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.
