WebGL2RenderingContext.clearBuffer[fiuv]()
The WebGL2RenderingContext.clearBuffer[fiuv]()
methods of
the WebGL 2 API clear buffers from the
currently bound framebuffer.
Syntax
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);
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.
Examples
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);
