WebGL2RenderingContext: clearBuffer[fiuv]() method
The WebGL2RenderingContext.clearBuffer[fiuv]()
methods of
the WebGL 2 API clear buffers from the
currently bound framebuffer.
Syntax
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)
Parameters
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 withclearBufferfi
).
drawBuffer
-
A
GLint
specifying the draw buffer to clear. values
-
An
Array
ofGLint
,GLuint
orGLfloat
values or anInt32Array
,Uint32Array
orFloat32Array
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.
Return value
None (undefined
).
Examples
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);
