WebGLRenderingContext: renderbufferStorage() method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
Note: This feature is available in Web Workers.
The WebGLRenderingContext.renderbufferStorage() method of
the WebGL API creates and initializes a
renderbuffer object's data store.
Syntax
renderbufferStorage(target, internalFormat, width, height)
Parameters
target-
A
GLenumspecifying the target renderbuffer object. Possible values:gl.RENDERBUFFER-
Buffer data storage for single images in a renderable internal format.
internalFormat-
A
GLenumspecifying 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
When using a WebGL 2 context, the following values are available additionally:
gl.R8gl.R8UIgl.R8Igl.R16UIgl.R16Igl.R32UIgl.R32Igl.RG8gl.RG8UIgl.RG8Igl.RG16UIgl.RG16Igl.RG32UIgl.RG32Igl.RGB8gl.RGBA8gl.SRGB8_ALPHA8(also available as an extension for WebGL 1, see below)gl.RGB10_A2gl.RGBA8UIgl.RGBA8Igl.RGB10_A2UIgl.RGBA16UIgl.RGBA16Igl.RGBA32Igl.RGBA32UIgl.DEPTH_COMPONENT24gl.DEPTH_COMPONENT32Fgl.DEPTH24_STENCIL8gl.DEPTH32F_STENCIL8
When using the
WEBGL_color_buffer_floatextension:ext.RGBA32F_EXT: RGBA 32-bit floating-point type.ext.RGB32F_EXT: RGB 32-bit floating-point type.
When using the
EXT_sRGBextension:ext.SRGB8_ALPHA8_EXT: 8-bit sRGB and alpha.
When using a WebGL 2 context and the
EXT_color_buffer_floatextension:gl.R16Fgl.RG16Fgl.RGBA16Fgl.R32Fgl.RG32Fgl.RGBA32Fgl.R11F_G11F_B10F
width-
A
GLsizeispecifying the width of the renderbuffer in pixels. height-
A
GLsizeispecifying the height of the renderbuffer in pixels.
Return value
None (undefined).
Examples
gl.renderbufferStorage(gl.RENDERBUFFER, gl.RGBA4, 256, 256);
