    <p>I have got the ascii ply file loading fine now. But it has a texture and i can not seem to get it to load not matter how i configure things. I am still learning this Three.js so bare with me.</p> <pre><code> cameraMain = new THREE.Camera(8, MainWidth / MainHeight, 1, 10000); sceneMain = new THREE.Scene(); ambientLightMain = new THREE.AmbientLight(0x202020); directionalLightMainRight = new THREE.DirectionalLight(0xffffff, 0.5); directionalLightMainLeft = new THREE.DirectionalLight(0xffffff, 0.5); pointLightMain = new THREE.PointLight(0xffffff, 0.3); directionalLightMainRight.position.x = dlpx; directionalLightMainRight.position.y = dlpy; directionalLightMainRight.position.z = dlpz; directionalLightMainRight.position.normalize(); directionalLightMainLeft.position.x = -dlpx; directionalLightMainLeft.position.y = dlpy; directionalLightMainLeft.position.z = dlpz; directionalLightMainLeft.position.normalize(); pointLightMain.position.x = plpx; pointLightMain.position.y = plpy; pointLightMain.position.z = plpz; sceneMain.addLight(ambientLightMain); sceneMain.addLight(directionalLightMainRight); sceneMain.addLight(directionalLightMainLeft); sceneMain.addLight(pointLightMain); rendererMain = new THREE.WebGLRenderer(); texture = THREE.ImageUtils.loadTexture('3D/'+ mainURL +'.jpg', {}, function() { rendererMain.render(sceneMain); }); rendererMain.domElement.style.backgroundColor = backgroundColor; rendererMain.setSize(MainWidth, MainHeight); rendererMain.domElement.addEventListener('DOMMouseScroll', onRendererMainScroll, false); rendererMain.domElement.addEventListener('mousewheel', onRendererMainScroll, false); rendererMain.domElement.addEventListener('dblclick', onRendererMainDblClick, false); rendererMain.domElement.addEventListener('mousedown', onRendererMainMouseDown, false); $("#viewerMain").append(rendererMain.domElement); window.addEventListener('mousemove', onMouseMove, false); window.addEventListener('mouseup', onMouseUp, false); </code></pre> <p>That chunk of code initializes the model. Some of it is not needed for question purposes, it has code for zooming, rotating, etc.. I know there is another line, i have it commented out but for some reason it wont show here so i will do it seperately.</p> <pre><code>material = new THREE.MeshBasicMaterial({map: texture}); </code></pre> <p>That line is after the loadTexture code.</p> <p>The rest of it is loaded with a loadPly function</p> <pre><code> var geometryMain = new THREE.Geometry(); for (i in event.data.content[0]) geometryMain.vertices.push(new THREE.Vertex(new THREE.Vector3(event.data.content[0][i][0], event.data.content[0][i][1], event.data.content[0][i][2]))); for (i in event.data.content[1]) geometryMain.faces.push(new THREE.Face3(event.data.content[1][i][0], event.data.content[1][i][1], event.data.content[1][i][2])); geometryMain.computeCentroids(); geometryMain.computeFaceNormals(); mainModel = new THREE.Mesh(geometryMain, new THREE.MeshLambertMaterial({color:0xffffff, shading:THREE.FlatShading})); sceneMain.addObject(mainModel); mainModel.overdraw = true; mainModel.doubleSided = true; </code></pre> <p>I have tried tweaking the THREE.mesh() section to include the material but it breaks everything. I have tried just adding the map:material to the MeshLambertMaterial, also a no go. Anyone have any insight? Sorry if this is over complicated but i am far from knowing this enough to be efficient yet.</p> <p>EDIT:</p> <p>If i add</p> <pre><code>map:THREE.ImageUtils.loadTexture('3D/'+ mainURL +'.jpg') </code></pre> <p>to the THREE.Mesh() line, i get </p> <blockquote> <p>.WebGLRenderingContext: GL ERROR :GL_INVALID_OPERATION : glDrawElements: attempt to access out of range vertices in attribute 2</p> </blockquote>

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.
