The WebGL2RenderingContext.clearBuffer[fiuv]() methods of the WebGL 2 API clear buffers from the currently bound framebuffer.
clearBufferfv(buffer, drawbuffer, values)
clearBufferfv(buffer, drawbuffer, values, srcOffset)
clearBufferiv(buffer, drawbuffer, values)
clearBufferiv(buffer, drawbuffer, values, srcOffset)
clearBufferuiv(buffer, drawbuffer, values)

clearBufferfi(buffer, drawbuffer, depth, stencil)
buffer
A GLenum specifying the buffer to clear. Possible values are:
gl.COLOR: Color buffer.gl.DEPTH: Depth buffer.gl.STENCIL: Stencil buffer.gl.DEPTH_STENCIL: clears depth and stencil buffers (used with clearBufferfi).drawBuffer
A GLint specifying the draw buffer to clear.
values
An Array of GLint, GLuint or GLfloat values or an Int32Array, Uint32Array or Float32Array specifying the values to clear to.
depth
A GLfloat specifying the value to clear a depth render buffer to.
stencil
A GLint specifying the value to clear the stencil render buffer to.
None (undefined).
