Check the Browser compatibility table carefully before using this in production.
The WebGL2RenderingContext.clearBuffer[fiuv]()
methods of the WebGL 2 API clear buffers from the currently bound framebuffer.
void gl.clearBufferfv(buffer, drawbuffer, values, optional srcOffset); void gl.clearBufferiv(buffer, drawbuffer, values, optional srcOffset); void gl.clearBufferuiv(buffer, drawbuffer, values, optional srcOffset); void gl.clearBufferfi(buffer, drawbuffer, depth, stencil);
buffer
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
GLint
specifying the draw buffer to clear.values
Array
of GLint
, GLuint
or GLfloat
values orInt32Array
, Uint32Array
or Float32Array
specifying the values to clear to.depth
GLfloat
specifying the value to clear a depth render buffer to.stencil
GLint
specifying the value to clear the stencil render buffer to.None.
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);
