WebGLRenderingContext: renderbufferStorage() method

View on MDN ↗

Available in 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 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.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).
