The WebGLRenderingContext.vertexAttrib[1234]f[v]() methods of the WebGL API specify values for generic vertex attributes.

Syntax

void <var>gl</var>.vertexAttrib1f(<var>index</var>, <var>v0</var>);
void <var>gl</var>.vertexAttrib2f(<var>index</var>, <var>v0</var>, <var>v1</var>);
void <var>gl</var>.vertexAttrib3f(<var>index</var>, <var>v0</var>, <var>v1</var>, <var>v2</var>);
void <var>gl</var>.vertexAttrib4f(<var>index</var>, <var>v0</var>, <var>v1</var>, <var>v2</var>, <var>v3</var>);

void <var>gl</var>.vertexAttrib1fv(<var>index</var>, <var>value</var>);
void <var>gl</var>.vertexAttrib2fv(<var>index</var>, <var>value</var>);
