    <p>Less words, more code =)</p> <pre><code>var objects = []; var camera, scene, renderer; document.addEventListener( 'mousedown', onDocumentMouseDown, false ); init(); render(); function onDocumentMouseDown( event ) { event.preventDefault(); var vector = new THREE.Vector3( ( event.clientX / window.innerWidth ) * 2 - 1, - ( event.clientY / window.innerHeight ) * 2 + 1, 0.5 ); projector.unprojectVector( vector, camera ); var ray = new THREE.Ray( camera.position, vector.subSelf( camera.position ).normalize() ); var intersects = ray.intersectObjects( objects ); if ( intersects.length &gt; 0 ) { console.log(intersects[ 0 ].object); } } function init() { container = document.getElementById( 'container' ); scene = new THREE.Scene(); camera = new THREE.PerspectiveCamera( 90, window.innerWidth / window.innerHeight, 1, 1100 ); camera.position.z = 50; scene.add( camera ); var particle = new THREE.Particle( new THREE.ParticleBasicMaterial( { map: THREE.ImageUtils.loadTexture( "img/satellite.png" ) } ) ); objects.push( particle ); //particle.scale.x = particle.scale.y = 0.25 scene.add( particle ); projector = new THREE.Projector(); renderer = new THREE.CanvasRenderer(); renderer.setSize( window.innerWidth, window.innerHeight ); container.appendChild( renderer.domElement ); } function render() { camera.lookAt( scene.position ); renderer.render( scene, camera ); } </code></pre> <p>As a result, we get clickable particle with a texture. But I don't understand several things:</p> <ol> <li><p>Why the "clickable" area of particle is so small? It works only if I click in the middle of a particle.</p></li> <li><p>Why is that particle so huge? The texture is this <img src="https://habrastorage.org/storage2/932/6cd/613/9326cd613aa9b4afe2f048ad67004aab.png" alt="16×16"> .png file and the particle is way more bigger than 16×16. How can I fix that? Yes, I know about particle.scale, that will make particle look smaller. But, the "clickable" area of particle woukd also become smaller.</p></li> </ol>

    1. COThat's an interesting problem. Maybe we can add some code to `Ray` so the particle area cutomisable... Do you mind reporting it as a feature request on the github page?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
