MDN’s new design is in Beta! A sneak peek: https://blog.mozilla.org/opendesign/mdns-new-design-beta/

WebGL2RenderingContext.invalidateFramebuffer()

This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

The WebGL2RenderingContext.invalidateFramebuffer() method of the WebGL 2 API invalidates the contents of attachments in a framebuffer.

Syntax

void gl.invalidateFramebuffer(target, attachments);

Parameters

target
A GLenum specifying the binding point (target). Possible values:
  • gl.FRAMEBUFFER: Collection buffer data storage of color, alpha, depth and stencil buffers used to render an image.
  • gl.DRAW_FRAMEBUFFER: Equivalent to gl.FRAMEBUFFER.
  • gl.READ_FRAMEBUFFER: Used as a source for reading operations.
attachments
An Array of GLenum specifying the attachment points to invalidate. Possible values:
  • gl.COLOR_ATTACHMENT{0-15}: Invalidates one of the framebuffer's color buffers.
  • gl.DEPTH_ATTACHMENT: Invalidates the framebuffer's depth buffer.
  • gl.STENCIL_ATTACHMENT: Invalidates the framebuffer's stencil buffer.
  • gl.DEPTH_STENCIL_ATTACHMENT: Invalidates both the framebuffer's depth and stencil buffer.

Return value

None.

Examples

gl.invalidateFramebuffer(gl.READ_FRAMEBUFFER, 
                         [gl.COLOR_ATTACHMENT0, gl.COLOR_ATTACHMENT1]);
