Is there a way to adjust the starting position of my geometry? Currently, it appears in the center of the canvas, but I would prefer it to be at the top left corner. Any suggestions on how to achieve this?
scene = new THREE.Scene();
camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 1, 10000);
camera.position.z = 1000;

Modify the cube's position by utilizing mesh.position.set(x, y, z)
To align your object to the top-left corner of the screen, I employed window.innerWidth and window.innerHeight.
Check out the revised JSFiddle demo showcasing your box in the upper-left section of the screen.
If you're unsatisfied with how the cube moves while being dragged and want to continue its normal rotation, eliminate the use of orbitControls. Instead, opt for this code (jQuery is necessary):
// jQuery required
var isDragging = false;
var previousMousePosition = {
x: 0,
y: 0
};
$(renderer.domElement).on('mousedown', function(e) {
isDragging = true;
})
.on('mousemove', function(e) {
var deltaMove = {
x: e.offsetX - previousMousePosition.x,
y: e.offsetY - previousMousePosition.y
};
if(isDragging) {
var deltaRotationQuaternion = new THREE.Quaternion()
.setFromEuler(new THREE.Euler(
toRadians(deltaMove.y * 1),
toRadians(deltaMove.x * 1),
0,
'XYZ'
));
mesh.quaternion.multiplyQuaternions(deltaRotationQuaternion, mesh.quaternion);
}
previousMousePosition = {
x: e.offsetX,
y: e.offsetY
};
});
$(document).on('mouseup', function(e) {
isDragging = false;
});
function toRadians(angle) {
return angle * (Math.PI / 180);
}
function toDegrees(angle) {
return angle * (180 / Math.PI);
}
