The WebGLRenderingContext.renderbufferStorage()
method of the WebGL API creates and initializes a renderbuffer object's data store.
Syntax
void gl.renderbufferStorage(target, internalFormat, width, height);
Parameters
- target
- A
Glenum
specifying the target renderbuffer object. Possible values:gl.RENDERBUFFER
: Buffer data storage for single images in a renderable internal format.
- internalFormat
- A
Glenum
specifying the internal format of the renderbuffer. Possible values:gl.RGBA4
: 4 red bits, 4 green bits, 4 blue bits 4 alpha bits.gl.RGB565
: 5 red bits, 6 green bits, 5 blue bits.gl.RGB5_A1
: 5 red bits, 5 green bits, 5 blue bits, 1 alpha bit.gl.DEPTH_COMPONENT16
: 16 depth bits.gl.STENCIL_INDEX8
: 8 stencil bits.gl.DEPTH_STENCIL

extension:ext.RGBA32F_EXT
: RGBA 32-bit floating-point type.ext.RGB32F_EXT
: RGB 32-bit floating-point type.
- When using the
EXT_sRGB
extension:ext.SRGB8_ALPHA8_EXT
: 8-bit sRGB and alpha.
- width
- A
GLsizei
specifying the width of the renderbuffer in pixels. - height
- A
GLsizei
specifying the height of the renderbuffer in pixels.
Return value
None.
Examples
gl.renderbufferStorage(gl.RENDERBUFFER, gl.RBGA4, 256, 256);

[1] WebGL 2 is enabled by default in Firefox Nightly. To enable it in a release version of Firefox, set the preference webgl.enable-prototype-webgl2
to true
in about:config.
[2] To use an experimental implementation of WebGL 2 in Chrome, you have to start Chrome with the runtime flag --enable-unsafe-es3-apis
.
