<DL>
<DD><p>Copies in an array of 16-bit vertex attributes. Positions, normals, and texture coordinates can be set with this method, but colors must be set with 8-bit input. This method is available only if <code>componentSize</code>, specified in the constructor, is 2.</p> <p>The vertex attributes are copied in starting from the first element of the source array. The number of elements copied in is <code>numComponents * numVertices</code>, where <code>numComponents</code> is either 2, 3, or 4, as specified at construction time. The source array must have at least that many elements.</p>
