WebGLRenderingContext: renderbufferStorage() method

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).

Examples

js

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