WebGL2RenderingContext.drawBuffers()

The WebGL2RenderingContext.drawBuffers() method of the WebGL 2 API defines draw buffers to which fragment colors are written into. The draw buffer settings are part of the state of the currently bound framebuffer or the drawingbuffer if no framebuffer is bound.

buffers

An Array of GLenum specifying the buffers into which fragment colors will be written. Possible values are:

• gl.NONE: Fragment shader output is not written into any color buffer.
• gl.BACK: Fragment shader output is written into the back color buffer.
• gl.COLOR_ATTACHMENT{0-15}: Fragment shader output is written in the nth color attachment of the current framebuffer.

None.

• If buffers contains not one of the accepted values, a gl.INVALID_ENUM error is thrown.

• WebGL2RenderingContext.clearBuffer[fiuv]()
