This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The WebGL2RenderingContext.vertexAttribIPointer() method of the WebGL 2 API specifies integer data formats and locations of vertex attributes in a vertex attributes array.
Syntax
void gl.vertexAttribIPointer(index, size, type, stride, offset);
Parameters
index- A
GLuintspecifying the index of the vertex attribute that is to be modified. size- A
GLintspecifying the number of components per vertex attribute. Must be 1, 2, 3, or 4. type- A
GLenumspecifying the data type of each component in the array. Must be one of:gl.BYTE,gl.UNSIGNED_BYTE,gl.SHORT,gl.UNSIGNED_SHORT,gl.INT, orgl.UNSIGNED_INT. stride- A
GLsizeispecifying the offset in bytes between the beginning of consecutive vertex attributes. offset- A
GLintptrspecifying an offset in bytes of the first component in the vertex attribute array. Must be a multiple oftype.
Return value
None.
Examples
gl.vertexAttribIPointer(0, 3, gl.INT, 0, 12);

[1] WebGL 2 is enabled by default in Firefox Nightly. To enable it in a release version of Firefox, set the preference webgl.enable-prototype-webgl2 to true in about:config.
[2] To use an experimental implementation of WebGL 2 in Chrome, you have to start Chrome with the runtime flag --enable-unsafe-es3-apis.
