methods of the WebGL 2 API clear buffers from the currently bound framebuffer.
js
clearBufferfv(buffer, drawbuffer, values) clearBufferfv(buffer, drawbuffer, values, srcOffset) clearBufferiv(buffer, drawbuffer, values) clearBufferiv(buffer, drawbuffer, values, srcOffset) clearBufferuiv(buffer, drawbuffer, values) clearBufferuiv(buffer, drawbuffer, values, srcOffset) 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
).
js
gl.clearBufferiv(gl.COLOR, 0, new Int32Array([r, g, b, a])); gl.clearBufferuiv(gl.COLOR, 0, new Uint32Array([r, g, b, a])); gl.clearBufferfv(gl.COLOR, 0, new Float32Array([r, g, b, a])); gl.clearBufferfv(gl.COLOR, 0, [0.0, 0.0, 0.0, 0.0]); gl.clearBufferfi(gl.DEPTH_STENCIL, 0, 1.0, 0);
