kandi X-RAY | TweenJS Summary
TweenJS is a simple tweening library for use in Javascript. It was developed to integrate well with the EaselJS library, but is not dependent on or specific to it (though it uses the same Ticker and Event classes by default). It supports tweening of both numeric object properties & CSS style properties.

QUESTION
I was just wondering if is it possible to use a library like tween or animejs to increment a value in a curve-based
With that I meant to increment a value from n to x using an easing curve.
My ultimate goal is to make like a acceleration animation to the camera so I would like to use like a "ease-in-out" CSS equivalent animation.
I tried to use anime.js to increment a property of an object and then update the position of the camera
...ANSWER
Answered 2021-Nov-10 at 16:07you can use anime, gsap etc. react-spring would probably be better. gasp/anime, watch out how you store their handles and anim-objects. local state is always kept in useState(() => new Foo())
. other than that, the easiest is lerp/damp, because they're inbuilt in threejs.

...ANSWER
Answered 2021-Oct-14 at 07:47In our case we were setting the draco decoder path to:
https://www.gstatic.com/draco/v1/decoders/
by calling:
this.dracoLoader.setDecoderPath("https://www.gstatic.com/draco/v1/decoders/");
But their recommended way is specifying the version in the URL:
https://www.gstatic.com/draco/versioned/decoders/1.4.3/
They released a new version yesterday, which explains the sudden errors: https://github.com/google/draco/releases/tag/1.4.3
Changing to the versioned URL fixed it for us. Another fix that worked was using JS instead of Webassembly:
this.dracoLoader.setDecoderConfig({ type: "js" });
QUESTION
I have looked through stack overflow and google and I have found how to CENTER a text geometry but that is not what I want to do.
I have a scene that just has a block of text that says "Buy Here!". Using the documentation in the three.js website and examples here I was able to do that after some struggling. I had some trouble finding out how to refer to that mesh since I had created the geometry inside a function, and it took hours for me to know about setting a name for it as a string so it can be accessible from different parent/child levels.
What I am NOT able to do now is to offset the text by some arbitrary number of units. I tried shifting it down by 5 units. No matter how I try to do it it isn't working. I either manage to make the text geometry disappear OR my whole scene is black.
Here is my code...
I have the basic scene setup working properly and I'll include it here but feel free to skip since I'm pretty sure this has nothing to do with the issue...
...ANSWER
Answered 2021-Jul-17 at 08:18I just wanna move it down a couple of units.
In this case use mesh.position.y = - 5;
. Changing the x
coordinate will move the mesh to the left or right. Here is a complete live example based on your code:
QUESTION
I am trying to animate some text by following a youtube video made by a guy named Gary Simon using GSAP.
I followed his instructions to the letter but nothing is moving. All he did was copy and paste the CDN for GSAP and CSSRulePlugin and I did the same but after telling my border to scale from 0 to 1 nothing happens. I slowed the video down to 0.5 to make sure I copied everything exactly but I can't find what I did wrong or if there is an extra step.
I tried typing npm install gsap and importing it but still nothing.

Use an object eg. myfog = { value: .5 }
and tween its value
property to what you desire.
Then in onUpdate
, set scene.fog
to a new THREE.FogExp2
with the current myfog.value
as a parameter.
QUESTION
I'm trying to animate the ThreeJS camera rotation using TweenJS, I have no problem tweening the camera.position, but for some reason camera.rotation refuses to change?
I've setup a minimal example using the code from the official ThreeJS documentation: https://threejs.org/docs/index.html#manual/en/introduction/Creating-a-scene
Basically it boils down to how this works fine:
new TWEEN.Tween(camera.position).to({x: newPos.x, y: newPos.y, z: newPos.z}).start()
while this doesn't work at all:
new TWEEN.Tween(camera.rotation).to({x: newRot.x, y: newRot.y, z: newRot.z}).start()
I think the code should be pretty self explanatory:

Answered 2021-Mar-22 at 21:59So for some reason what I had to do to fix this was instead of tweening camera.rotation
directly, I created a temporary object oldRot
, tweened that, and onUpdate
of the tween set the camera.rotation
to oldRot
.
So, instead of this:
