WebGL2RenderingContext.framebufferTextureLayer

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

void gl.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

None.

Examples

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