WebGLRenderingContext.vertexAttrib[1234]f[v]()

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);
