    <p>I am trying to change a cube image at run time by selecting an option from Select Form element. When running the code, the image changes after selecting, but the previous cube and image stays in the scene. </p> <p>How I clear / refresh / update the scene properly when changing the material / image / texture. </p> <pre><code>&lt;div id = "container"&gt;&lt;/div&gt; &lt;form id = "changesForm"&gt; Cube Image: &lt;br&gt; &lt;select id = "cubeImage"&gt; &lt;option value = "random"&gt;Random&lt;/option&gt; &lt;option value = "image1"&gt;First Image&lt;/option&gt; &lt;option value = "Image2"&gt;Second Image&lt;/option&gt; &lt;/select&gt; &lt;br&gt; &lt;/form&gt; &lt;script type = "text/javascript"&gt; window.onload = windowLoaded; function windowLoaded(){ if (window.addEventListener){ init(); animate(); //document.getElementById('container').addEventListener('mousemove', containerMouseover, false); window.addEventListener( 'resize', onWindowResize, false ); var cubeImage = document.getElementById('cubeImage'); cubeImage.addEventListener("change", changeCubeImage, false); } else if (window.attachEvent){ //init(); //animate(); //document.getElementById('container').attachEvent('onmousemove', containerMouseover); //window.attachEvent( 'onresize', onWindowResize); } function changeCubeImage(e){ //e.preventDefault(); var target = e.target; cubeImageCheck = target.value; createCube(); } // rest code ..... function createCube(){ //image var cubeImg; switch (cubeImageCheck){ case 'random': { // should load the 2 images random - to do cubeImg = new THREE.ImageUtils.loadTexture("img1.jpg"); break; } case 'image1': { cubeImg = new THREE.ImageUtils.loadTexture("image1.jpg"); break; } case 'image2': { cubeImg = new THREE.ImageUtils.loadTexture("image2.jpg"); break; } } cubeImg.needsUpdate = true; // geometry var cubeGeometry = new THREE.CubeGeometry(200,200,200);; // material var cubeMaterial = new THREE.MeshPhongMaterial({ map: cubeImg, side:THREE.DoubleSide, transparent: true, opacity:1, shading: THREE.SmoothShading, shininess: 90, specular: 0xFFFFFF }); cubeMaterial.map.needsUpdate = true; //mesh cubeMesh = new THREE.Mesh(cubeGeometry, cubeMaterial); cubeMesh.needsUpdate = true; scene.add(cubeMesh); } // rest .... </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
