multiple timeline with scrollmagic in tweenmax oncomplete function is not working
.add(TweenLite.fromTo ('.title2' , 0.3, {css:{opacity:0}}, {css:{opacity:1},onComplete:function() {
function pathPrepare ($el) {
var lineLength = $el[0].getTotalLength();
$el.css("stroke-dasharray", lineLength);
$el.css("stroke-dashoffset", lineLength);
}
var $word = $("polyline#svg_2");
pathPrepare($word);
var tl1 = new TimelineLite()
.add(TweenMax.to($word, 0.9, {strokeDashoffset: 0, ease:Linear.easeNone,onComplete:function(){
var tlbox = new TimelineLite()
.add(TweenLite.fromTo ('#grapher' , 0.3, {css:{opacity:0}}, {css:{opacity:1,display:'block'},onComplete:function() {}}))
var scene = new ScrollMagic.Scene()
.setTween(tlbox)
.addTo(controller);
}}))
// .add(TweenMax.to("path", 1, {stroke: "#33629c", ease:Linear.easeNone}), 0);
var scene = new ScrollMagic.Scene({triggerElement: "#trigger4", duration: 300, offset: 0})
.setTween(tl1)
.addTo(controller);
}}),0 )
on this code scrollmagic controller is not working properly please help me from this
try this without adding timeline tweens inside onComplete function
var tl1 = new TimelineMax()
.add(TweenMax.to($word, 0.9, {strokeDashoffset: 0, ease:Linear.easeNone,onComplete:function(){}}))
.add(TweenLite.fromTo ('#grapher' , 0.3, {css:{opacity:0,display:'none'}}, {css:{opacity:1,display:'inline-block'},onComplete:function() {}}))
var scene = new ScrollMagic.Scene({triggerElement: "#trigger4", duration: 300, offset: 0})
.setTween(tl1)
.addTo(controller);

Hello everyone，I have meet a strange problem which is that I loaded a gltf model in three.js and set color for it.When zooming in it has colors, but when zooming out,it is all black.And when I directly set color for it's material,it can works well.
Thank you.
here is the sample sreenphotos and code.
loadGlbModel() {
const loader = new GLTFLoader();
loader.load(
`/three/eiffel-tower.gltf`,
(gltf) => {
const geometry = gltf.scene.children[0].geometry;
const positions = geometry.attributes.position;
const count = positions.count;
geometry.setAttribute(
"color",
new THREE.BufferAttribute(new Float32Array(count * 3), 3)
);
const color = new THREE.Color();
const colors = geometry.attributes.color;
const radius = 200;
debugger;
for (let i = 0; i < count; i++) {
color.setHSL(positions.getY(i) / radius / 2, 1.0, 0.5);
colors.setXYZ(i, 1, 0, 0);
}
const material = new THREE.MeshPhongMaterial({
color: 0xffffff,
flatShading: true,
vertexColors: true,
shininess: 0,
});
const wireframeMaterial = new THREE.MeshBasicMaterial({
color: 0x000000,
wireframe: true,
transparent: true,
});
let mesh = new THREE.Mesh(geometry, material);
let wireframe = new THREE.Mesh(geometry, wireframeMaterial);
mesh.add(wireframe);
mesh.scale.set(0.1, 0.1, 0.1);
const redColor = new THREE.Color(1, 0, 0);
console.log(mesh);
// mesh.children[0].material.color = redColor;
const light = new THREE.DirectionalLight(0xffffff);
light.position.set(0, 0, 1);
this.scene.add(light);
this.scene.add(mesh);
},
(xhr) => {
console.log((xhr.loaded / xhr.total) * 100 + "% loaded");
},
(error) => {
console.error(error);
}
);
},
You are rendering the wireframe version too, which consists of lines in screen-space. As you zoom out, these lines maintain the same width in pixels, thus covering everything else.
Do you wish to render the fireframe too? If not, don't. If you do, then consider hiding it as the user zooms out.
How can I print the values of an array using three.js textGeometry. Trying the following code but no output.
`for(let i=0;i<=4;i++)
{
let arr = [1,2,3,4,5,6,7,8];
let char = arr[i];
let loader = new THREE.FontLoader();
let font = loader.parse(fontJSON);
let geometry = new THREE.TextBufferGeometry(char ,{font : font , size : 1 , height : 0.1 });
let material = new THREE.MeshBasicMaterial({ color : 0xffffff });
let text = new THREE.Mesh(geometry , material);
text.position.set(i,0,0);
scene.add(text);
}`
You have to make sure to provide a string to TextBufferGeometry, no number. You can easily ensure this by calling toString() on your char variable. I've refactored your code a bit to show you a complete example.
let camera, scene, renderer;
init();
animate();
function init() {
camera = new THREE.PerspectiveCamera(70, window.innerWidth / window.innerHeight, 0.01, 10);
camera.position.z = 8;
scene = new THREE.Scene();
const material = new THREE.MeshBasicMaterial({
color: 0xffffff
});
const arr = [1, 2, 3, 4, 5, 6, 7, 8];
const loader = new THREE.FontLoader();
loader.load('https://threejs.org/examples/fonts/helvetiker_regular.typeface.json', (font) => {
for (let i = 0; i <= 4; i++) {
const char = arr[i];
const geometry = new THREE.TextBufferGeometry(char.toString(), {
font: font,
size: 1,
height: 0.1
});
const text = new THREE.Mesh(geometry, material);
text.position.set(i, 0, 0);
scene.add(text);
}
});
renderer = new THREE.WebGLRenderer({
antialias: true
});
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
}
function animate() {
requestAnimationFrame(animate);
renderer.render(scene, camera);
}
body {
margin: 0;
}
canvas {
display: block;

I am using the jspdf library to create a pdf and its working out great. I am now trying to append to that pdf another existing pdf. At the moment when my user clicks the download button it fires off two separate downloads. I was thinking that a work around might be creating two images and adding them to my pdf created with Jspdf. Has anyone appended an existing pdf to a pdf generated using jspdf?
$(document).ready(function () {
var doc = new jsPDF('p', 'pt', 'letter');
var imgData = 'cats.jpg'
var specialElementHandlers = {
'#content': function (element, renderer) {
return true;
}
};
$('#cmd').click(function () {
doc.addImage(imgData, 'JPEG', 0, 250, 615, 200);
doc.fromHTML($('#content').get(0), 0, 0, {
'elementHandlers': specialElementHandlers
});
doc.save('TemporaryIdCard.pdf');
});
});
I ended up hacking an answer from here.
Not thrilled about it but it works. I created images from the content in the PDF I was trying to append and then added each as a page to my doc
var doc = new jsPDF('p', 'pt', 'letter');
var imgData = 'cats.jpeg';
var imgData2 = 'dogs.jpeg';
var imgData3 = 'kittens.jpeg';
var specialElementHandlers = {
'#content': function (element, renderer) {
return true;
}
};
var pageHeight = doc.internal.pageSize.height;
var y = 800;
var x = 800;
$('#cmd').click(function () {
doc.addImage(imgData, 'JPEG', 0, 250, 615, 200);
doc.fromHTML($('#content').get(0), 0, 0, {
'elementHandlers': specialElementHandlers
});
if (y >= pageHeight) {
doc.addPage();
doc.addImage(imgData3, 'JPEG', 45, 45, 500, 550);
y = 0;
}
if (x >= pageHeight) {
doc.addPage();
doc.addImage(imgData2, 'JPEG', 50, 70, 500, 500);
x = 0;
}
doc.save('TemporaryIdCard.pdf');
});
To get you into the context, let say i have a camera
camera = new THREE.PerspectiveCamera();
camera.position.set(1,1,1);
camera.lookAt(scene.position);
camera.rotation.set(Math.PI/2, 0 ,0) // <=== this is lost when the orbit control move
then i create an orbit control
controls = new THREE.OrbitControls(camera, renderer.domElement);
The Problem is that when i use the orbit control by dragging the mouse on click or zooming, the camera rotation is lost.
I tried using controls.update() but it's not working
Edit
Here is a link for a jsfiddle
var camera;
var scene;
var conrols;
var renderer;
function init() {
scene = new THREE.Scene();
renderer = new THREE.WebGLRenderer({
alpha: true,
antialias: true
});
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 0.1, 10000);
camera.position.set(0, 0, 5);
scene.add(camera);
scene.add(new THREE.AmbientLight(0xffffff, 0.6));
var light1 = new THREE.HemisphereLight(0xffffbb, 0x080820, 0.7)
scene.add(light1);
var light2 = new THREE.SpotLight(0xffffff, 0.5);
light2.position.set(4, 7, 23);
scene.add(light2);
var light3 = new THREE.SpotLight(0xffffff, 0.5);
light3.position.set(4, 7, -23);
//scene.add(light3);
var geometry = new THREE.BoxGeometry(2, 1, 1);
var material = new THREE.MeshLambertMaterial({
color: 0x00ffff
});
var cube = new THREE.Mesh(geometry, material);
scene.add(cube);
controls = new THREE.OrbitControls(camera, renderer.domElement);
}
function animate() {
requestAnimationFrame(animate);
renderer.render(scene, camera);
}
document.getElementById('button').onclick = function() {
//console.log("position");
//console.log(camera.position);
//console.log("rotation");
//console.log(camera.rotation);
camera.rotation.set(0, 0, 1.57);
// camera.position.set(-0.041, 1.9, -1.21);
}
init();
animate();

<button id="button">change rotation</button>
in my original application i have a 3D foot mesh. Sometimes i need to have a vertical view of the backfoot with only a click. So i apply a camera rotation. but when i move the camera with orbit control the camera rotation jumps to the old value.
You can switch to a second camera like 2pha says or you can set controls.enableRotate = false;
I am having a problem finding information on using actionscript 2 to move an object along a more complicated path. I have no issue if i need to tween in the x or y direction, or at the same time, but If i wanted an object to follow a curvy path could someone provide me sample code for a way to follow a motion guide or a curved path like a bezier?
here is my usual code:
Tween1();
function Tween1(){
setTimeout(theTween, 0);
function theTween(){
var myTween:Tween = new Tween(Object, "_x", Regular.easeOut, 0, 100, 1, true);
var myTween:Tween = new Tween(Object, "_y", Regular.easeOut, 0, 100, 1, true);
}
try this Animate along bezier curve
var circle:Shape = Shape(addChild(new Shape));
with(circle.graphics) beginFill(0x000000), drawCircle(0,0,5);
var bezierPoint:Point = new Point();
function bezier(a:Number, x1:Number, y1:Number, x2:Number, y2:Number, x3:Number, y3:Number):void {
var b:Number =1-a;
var pre1:Number=a*a;
var pre2:Number=2*a*b;
var pre3:Number=b*b;
bezierPoint.x = pre1*x1 + pre2*x2 + pre3*x3;
bezierPoint.y = pre1*y1 + pre2*y2 + pre3*y3;
}
var inc:Number = 0;
var theta:Number = 0;
addEventListener(Event.ENTER_FRAME, onLoop);
function onLoop(evt:Event):void {
graphics.clear();
graphics.lineStyle(0,0xFF0000);
graphics.moveTo(200,200);
graphics.curveTo(mouseX, mouseY, 400, 200);
inc += .03;
inc %= 1;
bezier(inc, 200, 200, mouseX, mouseY, 400, 200);
circle.x = bezierPoint.x;
circle.y = bezierPoint.y;
}
