must be set to

target
number of samples to be used with
the renderbuffer object's storage.
Must be less than
GL_MAX_SAMPLES
(
glRenderbufferStorageMultisample
only)
samples
must be a format that can be used as a color
buffer, depth buffer, or stencil buffer.
internalformat
The supported formats are listed in Tables 12-1
and 12-2.
width of the renderbuffer in pixels;
width
must be less than or equal to
GL_MAX_RENDERBUFFER_SIZE
.
height
height of the renderbuffer in pixels;
must be less than or equal to
GL_MAX_RENDERBUFFER_SIZE
.
be values that are smaller than the maximum renderbuffer size
supported by the implementation. The minimum size value that must
be supported by all OpenGL ES implementations is 1. The actual
maximum size supported by the implementation can be queried using
the following code:
GLint maxRenderbufferSize = 0;
glGetIntegerv(GL_MAX_RENDERBUFFER_SIZE, &maxRenderbufferSize);
The
internalformat
argument specifies the format that the application
would like to use to store pixels in the renderbuffer object. Table 12-1
lists the renderbuffer formats to store a color-renderable buffer, and
Table 12-2 lists the formats to store a depth-renderable or stencil-
renderable buffer.
