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.framebufferTextureLayer() method of the WebGL 2 API attaches a single layer of a texture to a framebuffer.

This method is similar to WebGLRenderingContext.framebufferTexture2D(), but only a given single layer of the texture level is attached to the attachment point.


void <var>gl</var>.framebufferTextureLayer(<var>target</var>, <var>attachment</var>, <var>texture</var>, <var>level</var>, <var>layer</var>);


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.
A GLenum specifying the attachment point for the texture. Possible values:
  • gl.COLOR_ATTACHMENT{0-15}: Attaches the texture to one of the framebuffer's color buffers.
  • gl.DEPTH_ATTACHMENT: Attaches the texture to the framebuffer's depth buffer.
  • gl.STENCIL_ATTACHMENT: Attaches the texture to the framebuffer's stencil buffer.
  • gl.DEPTH_STENCIL_ATTACHMENT: depth and stencil buffer.
A WebGLTexture object whose image to attach.
A GLint specifying the mipmap level of the texture image to attach.
A GLint specifying the layer of the texture image to attach.

Return value



gl.framebufferTextureLayer(gl.FRAMEBUFFER, gl.COLOR_ATTACHMENT0, 
                           texture, 0, 8);
