One of my functions involves creating a track using 3D points from a separate file called trackline.json. The example data in the file looks something like this:
[{"x":5.01088018657063,"y":0.033095929202426655,"z":-1.469083126575439},{"x":-2.836023686139761,"y":1.2315534616542192,"z":-2.623173656748311},{"x":-5.188269059945695,"y":-3.889753328348702,"z":2.4758137354826646},{"x":0.5400173030307891,"y":-4.415289185011361,"z":3.7757418987784406},{"x":4.475184816920873,"y":-0.3696880702837009,"z":0.6426064577081578}]
This function creates multiple 3D lines (vectors) that are meant to serve as a camera path. However, the lines have sharp edges at each end. I am looking for a way to calculate additional points to smooth out these lines or any other efficient method to achieve this.
Below is the code snippet responsible for creating the track lines:
setupTrackline() {
fetch('trackline.json')
.then(response => {
return response.json();
})
.then(data => {
// Process the data if needed
console.log(data); // Check the retrieved data
this.setupTracklineWithData(data);
})
.catch(error => {
console.error('Error fetching trackline.json:', error);
});
}
setupTracklineWithData(data) {
// Assuming the data is an array of Vector3 objects, adjust this part accordingly
const points = data.map(position => new THREE.Vector3(position.x, position.y, position.z));
const lineGeometry = new THREE.BufferGeometry().setFromPoints(points);
const lineMaterial = new THREE.LineBasicMaterial({ color: 0x00dd00 }); // Green color for the line
this.trackline = new THREE.Line(lineGeometry, lineMaterial);
}
Here's a simple 2D visualization of the issue:
