AI Generated Camera Sweep

Example AI Command Script to Generate Three.js Camera Sweeps. What I’ve noticed about building AI scripts is that you can store and modify them, and the technology learns from you and how you want things done. The scary part is that after a while, the AI starts to predict exactly what your next move will be… LOL :grinning:

I’m working on a project using Three.js, and I need to create a script for animating camera movement along a predefined path. Could you please write a script for me that accomplishes the following?

Define a set of points that represent the camera’s path.
Specify the duration of the camera movement animation.
Set the camera to continuously look at a specific target point during the movement.
Implement easing for smoother animation.
Use Catmull-Rom interpolation to interpolate along the path.
Here are the details I’d like to include in the script:

Start point: (1000, 1000, 1000)
End point: (0, 10, 300)
Target point for the camera to look at: (0, 0, 0)
Duration of the movement: 5000 milliseconds (5 seconds)
I’d appreciate it if you could provide the JavaScript code for this camera movement animation. Let me know if you need any further clarification.

 // Define the camera's path points
    const pathPoints = [
        new THREE.Vector3(1000, 1000, 1000), // Start point
        new THREE.Vector3(0, 10, 300),       // End point
        // Add more points as needed
    ];

    // Define the duration of the movement in milliseconds
    const duration = 5000; // 5 seconds

    // Define the target point for the camera to look at
    const targetPoint = new THREE.Vector3(0, 0, 0);

    // Define the start time of the movement
    let startTime = null;


    // Function to animate the movement of the camera along the path with easing
    function animateCameraMovement() {
        // If the start time is not defined, set it to the current time
        if (startTime === null) {
            startTime = Date.now();
        }

        // Calculate the elapsed time since the start of the movement
        const elapsedTime = Date.now() - startTime;

        // Calculate the interpolation factor (progress) using easing function
        const progress = easeInOutQuad(Math.min(elapsedTime / duration, 1));

        // Interpolate along the path
        const position = interpolatePath(pathPoints, progress);

        // Update the camera's position
        camera.position.copy(position);

        // Update the camera's rotation to look at the target point
        camera.lookAt(targetPoint);

        // If the movement is not finished, request the next frame
        if (progress < 1) {
            requestAnimationFrame(animateCameraMovement);
        }
    }

    // Easing function for smoother animation
    function easeInOutQuad(t) {
        return t < 0.5 ? 2 * t * t : -1 + (4 - 2 * t) * t;
    }


    // Function to interpolate along the path using Catmull-Rom interpolation
    function interpolatePath(points, progress) {
        const curve = new THREE.CatmullRomCurve3(points);
        return curve.getPointAt(progress);
    }


    // Call the function to start the camera movement animation
    animateCameraMovement();
