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.vertexAttribI4[u]i[v]()
methods of the WebGL 2 API specify integer values for generic vertex attributes.
Syntax
void gl.vertexAttribI4i(index, v0, v1, v2, v3); void gl.vertexAttribI4ui(index, v0, v1, v2, v3); void gl.vertexAttribI4iv(index, value); void gl.vertexAttribI4uiv(index, value);
Parameters
index
- A
GLuint
specifying the position of the vertex attribute to be modified. v0, v1, v2, v3
- An integer
Number
for the vertex attribute value. value
-
A
Uint32Array
orInt32Array
for integer vector vertex attribute values.
Return value
None.
Examples
gl.vertexAttribI4i(a_foobar, 10);

[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
