if (ind === 0 || ind === path.length - 1) {
newPath.push(point);
return;
}
var tmpNeighbour = neighbour;
if (ind < neighbour) {
tmpNeighbour = ind;
} else if (ind >= path.length - neighbour) {
tmpNeighbour = path.length - 1 - ind;

const onDocumentMouseDown = (event) => {
let state: State = store().getState()
let scene: THREE.Scene = getScene(state)
let camera: THREE.Camera = getCamera(state)
let renderer: THREE.Renderer = getRenderer(state)
event.preventDefault()
mouse.x = (event.clientX / renderer.domElement.width) * 2 - 1
mouse.y = -(event.clientY / renderer.domElement.height) * 2 + 1
let vector = new THREE.Vector3(mouse.x, mouse.y, 0.5)
vector.unproject(camera)
let dir = vector.sub(camera.position).normalize()
let distance = -camera.position.z / dir.z
let pos = camera.position.clone().add(dir.multiplyScalar(distance))
pos.z = 250
store().dispatch({
type: 'MOUSE_DOWN',
pos: pos
})
}示例5: 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;
