WebGL2RenderingContext: framebufferTextureLayer() method
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.
Syntax
framebufferTextureLayer(target, attachment, texture, level, layer)
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.
-
attachment
-
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.
-
texture
-
A WebGLTexture
object whose image to attach.
-
level
-
A GLint
specifying the mipmap level of the texture image to attach.
-
layer
-
A GLint
specifying the layer of the texture image to attach.
Return value
Examples
gl.framebufferTextureLayer(gl.FRAMEBUFFER, gl.COLOR_ATTACHMENT0, texture, 0, 8);
