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

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.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.
