The WebGLRenderingContext.vertexAttrib[1234]f[v]()
methods of the WebGL API specify values for generic vertex attributes.
Syntax
void gl.vertexAttrib1f(index, v0); void gl.vertexAttrib2f(index, v0, v1); void gl.vertexAttrib3f(index, v0, v1, v2); void gl.vertexAttrib4f(index, v0, v1, v2, v3); void gl.vertexAttrib1fv(index, value); void gl.vertexAttrib2fv(index, value); void gl.vertexAttrib3fv(index, value); void gl.vertexAttrib4fv(index, value);
Parameters
index
- A
GLuint
specifying the position of the vertex attribute to be modified. v0, v1, v2, v3
- A floating point
Number
for the vertex attribute value. value
-
A
Float32Array
for floating point vector vertex attribute values.
Return value
None.
Examples
const a_foobar = gl.getAttribLocation(shaderProgram, 'foobar'); //either set each component individually: gl.vertexAttrib3f(a_foobar, 10.0, 5.0, 2.0); //or provide a Float32Array: const floatArray = new Float32Array([10.0, 5.0, 2.0]); gl.vertexAttrib3fv(a_foobar, floatArray);
