Web/API/WebGLRenderingContext/renderbufferStorage

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

Syntax

void gl.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.

Examples

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