The WebGL2RenderingContext.getInternalformatParameter()
method of the WebGL 2 API returns information about implementation-dependent support for internal formats.
Syntax
any gl.getInternalformatParameter(target, internalformat, pname);
Parameters
target
- A
Glenum
specifying the target renderbuffer object. Possible values:gl.RENDERBUFFER
: Buffer data storage for single images in a renderable internal format.
internalformat
- A
GLenum
specifying the internal format about which to retrieve information (must be a color-renderable, depth-renderable or stencil-renderable format). pname
- A
GLenum
specifying the type of information to query. Possible values:gl.SAMPLES
: Returns aInt32Array
containing sample counts supported forinternalformat
in descending order.
Return value
Depends on the requested information (as specified with pname
). It is an Int32Array
if pname
is gl.SAMPLES
.
Examples
var samples = gl.getInternalformatParameter(gl.RENDERBUFFER, gl.RGBA8, gl.SAMPLES);
