Hey there! I've been tinkering around with Three.js and loading JSON models using JSONLoader. I also have TrackballControls.js set up for some basic interaction. However, I've noticed that the rotation behaves differently after moving (PAN) the object. Do you happen to know how I can change the rotation back to the model's center after a PAN movement?
Your help is greatly appreciated!
Instead of relying on trackball controls to rotate the camera, it is recommended to rotate the mesh based on quaternion. This can help prevent strange rotation behavior after panning.
trackBallControls.noRotate = true;
if (isDragging === true) {
var deltaMove = {
x: event.offsetX -previousMousePosition.x,
y: event.offsetY -previousMousePosition.y
};
var deltaRotationQuaternion = new THREE.Quaternion()
.setFromEuler(new THREE.Euler(toRadians(deltaMove.y * 0.3),
toRadians(deltaMove.x * 0.3),
0,
'XYZ'
));
if (event.which === 1) {
mesh.quaternion.multiplyQuaternions(deltaRotationQuaternion, mesh.quaternion);
}
}
previousMousePosition = {
x: event.offsetX,
y: event.offsetY
};
To set isDragging to false in mouse up event, and to true in mousedown event.
function toRadians(angle) {
return angle * (Math.PI / 180);
}
