示例1: handleVertex
function handleVertex(v) {
n.fromArray(normals, v * 3);
n2.copy(n);
t = tan1[v];
// Gram-Schmidt orthogonalize
tmp.copy(t);
tmp.sub(n.multiplyScalar(n.dot(t))).normalize();
// Calculate handedness
tmp2.crossVectors(n2, t);
test = tmp2.dot(tan2[v]);
w = (test < 0.0) ? - 1.0 : 1.0;
tangents[v * 4] = tmp.x;
tangents[v * 4 + 1] = tmp.y;
tangents[v * 4 + 2] = tmp.z;
