Upon loading a 3D model with threejs, I am able to initiate animation clips. However, instead of simply running the animation, I desire to navigate to a specific point in the sequence on button click. For instance, if my animation clip is 1-minute long, when a user clicks a button, I aim to manipulate the geometry to mimic its appearance at the 30-second mark within the animation.
Is there a method to achieve this functionality using threejs, or do you have an alternative suggestion?
Do you know if there is a way to achieve this using threejs, or perhaps you have another suggestion?
A potential solution could involve playing back an animation clip in threejs and pausing it to set the time property accordingly. Here is an example of how this can be done:
const clipAction = mixer.clipAction( clip );
clipAction.play();
clipAction.paused = true;
clipAction.time = 0.5;
You can see this approach in action here: https://jsfiddle.net/w6catxfh/1/
If your animation can be controlled by time, there are different approaches you can take to make a cube move upwards. One option is to directly instruct the cube to move up by a specific distance in each animation loop:
var animate = function () {
requestAnimationFrame( animate );
cube.position.y += 0.01;
renderer.render( scene, camera );
};
Alternatively, you can define the cube's position as a function of time for a similar animation effect:
var currentTime = 0;
var animate = function () {
requestAnimationFrame( animate );
cube.position.y = 0.01 * currentTime;
currentTime += 1;
renderer.render( scene, camera );
};
Both methods result in the same visual outcome, but manipulating the currentTime variable allows for navigation through the animation timeline.
