WebGLRenderingContext.vertexAttrib

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
