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.

The WebGLRenderingContext.renderbufferStorage() method of the WebGL API creates and initializes a renderbuffer object's data store.

Syntax

js
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

When using a WebGL 2 context, the following values are available additionally:

  • gl.R8
  • gl.R8UI
  • gl.R8I
  • gl.R16UI
  • gl.R16I
  • gl.R32UI
  • gl.R32I
  • gl.RG8
  • gl.RG8UI
  • gl.RG8I
  • gl.RG16UI
  • gl.RG16I
  • gl.RG32UI
  • gl.RG32I
  • gl.RGB8
  • gl.RGBA8
  • gl.SRGB8_ALPHA8 (also available as an extension for WebGL 1, see below)
  • gl.RGB10_A2
  • gl.RGBA8UI
  • gl.RGBA8I
  • gl.RGB10_A2UI
  • gl.RGBA16UI
  • gl.RGBA16I
  • gl.RGBA32I
  • gl.RGBA32UI
  • gl.DEPTH_COMPONENT24
  • gl.DEPTH_COMPONENT32F
  • gl.DEPTH24_STENCIL8
  • gl.DEPTH32F_STENCIL8

When using the WEBGL_color_buffer_float 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.

When using a WebGL 2 context and the EXT_color_buffer_float extension:

  • gl.R16F
  • gl.RG16F
  • gl.RGBA16F
  • gl.R32F
  • gl.RG32F
  • gl.RGBA32F
  • gl.R11F_G11F_B10F
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 (undefined).

js
gl.renderbufferStorage(gl.RENDERBUFFER, gl.RGBA4, 256, 256);
