WebGLRenderingContext.renderbufferStorage()

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

    • 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
