WebGL2RenderingContext.framebufferTextureLayer() 方法在 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 gl.framebufferTextureLayer(target, attachment, texture, level, layer);

target


									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


									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


									WebGLTexture

object whose image to attach.

level


									GLint

specifying the mipmap level of the texture image to attach.

layer


									GLint

specifying the layer of the texture image to attach.

None.

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