I need assistance with positioning a rendered STL file from Thingiverse in the center of the screen using Three.js and the THREE.STLLoader(). Currently, I have to adjust the rotation properties based on touch coordinates to get the object where I want it. However, I want the object to be centered on the screen and rotate from the center when moving my finger over the screen.
Below is my current code, any help would be greatly appreciated:
[Your rewritten code here]
Through my exploration of the Three.js source code, I have discovered the solution - the key is to 'center' the geometry before creating the mesh using the geometry.center() method. Here is the updated THREE.STLoader(); load method that I have implemented:
// STL
var loader = new THREE.STLLoader();
loader.load(window.newFilePath, function ( geometry ) {
geometry.center()
var material = new THREE.MeshLambertMaterial({color: 0xFF0000});
stlMesh = new THREE.Mesh(geometry, material);
camera.position.z = geometry.boundingBox.size().z+200
//stlMesh.translateY()
scene.add(stlMesh);
});
