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
