    <p>I am trying to build my own three.js geometry. However, when I try to define it, like this:</p> <pre><code>geometry = new THREE.FreeWallGeometry( 3, 5 ); </code></pre> <p>I get the error "TypeError: v is undefined" from the function <code>addSelf</code> at line 714 in three.js.</p> <p>How do I find out what triggers this error?</p> <p>This is the current code for my homemade geometry:</p> <pre><code>define( [ "libs/three.js/build/three", ], function ( three ) { console.log("setting up makeControls. regards, makeControls"); //THREE.FreeWallGeometry = function ( length, height, depth, segmentsWidth, segmentsHeight, segmentsDepth, materials, sides ) { // X = length, Y = height, Z = depth, THREE.FreeWallGeometry = function ( noOfSegments, segmentLength ) { THREE.Geometry.call( this ); var t1, t2, normal = new THREE.Vector3( 0, 0, 1); freePlane; var freePlane = function ( self, parametricPlane_X, parametricPlane_Y, parametricPlane_Z, equidistantSampler_T1, equidistantSampler_T2 ) { for ( t2 = 0; t2 &lt; noOfSegments; t2 ++ ) { for ( t1 = 0; t1 &lt; noOfSegments; t1 ++ ) { console.log("free: t1, t2 ", t1, t2); //var x = t1 * segmentT1_length - length_half; //var y = t2 * segmentT2_length - height_half; var x = parametricPlane_X ( t1, t2 ); var y = parametricPlane_Y ( t1, t2 ); var z = parametricPlane_Z ( t1, t2 ); console.log("free: x, y z ", x, y, z); self.vertices.push( new THREE.Vector3( x, - y, z ) ); } } for ( t2 = 0; t2 &lt; noOfSegments; t2 ++ ) { for ( t1 = 0; t1 &lt; noOfSegments; t1 ++ ) { var a = t1 + noOfSegments * t2; var b = t1 + noOfSegments * ( t2 + 1 ); var c = ( t1 + 1 ) + noOfSegments * ( t2 + 1 ); var d = ( t1 + 1 ) + noOfSegments * t2; //console.log ("free: a, b, c, d ", a, b, c, d); var face = new THREE.Face4( a, b, c, d ); if (!self.vertices[face.a]) { console.log("this face.a can't index vertices: ", face.a); } if (!self.vertices[face.b]) { console.log("this face.b can't index vertices: ", face.b); } if (!self.vertices[face.c]) { console.log("this face.c can't index vertices: ", face.c); } if (!self.vertices[face.d]) { console.log("this face.d can't index vertices: ", face.d); } face.normal.copy( normal ); face.vertexNormals.push( normal.clone(), normal.clone(), normal.clone(), normal.clone() ); self.faces.push( face ); self.faceVertexUvs[ 0 ].push( [ new THREE.UV( t1 / noOfSegments, 1 - t2 / noOfSegments ), new THREE.UV( t1 / noOfSegments, 1 - ( t2 + 1 ) / noOfSegments ), new THREE.UV( ( t1 + 1 ) / noOfSegments, 1 - ( t2 + 1 ) / noOfSegments ), new THREE.UV( ( t1 + 1 ) / noOfSegments, 1 - t2 / noOfSegments ) ] ); } } } var parametricPlane_X = function ( t1, t2 ) { x = t1; return x; }; var parametricPlane_Y = function ( t1, t2 ) { y = t1; return y; }; var parametricPlane_Z = function ( t1, t2 ) { z = t1 * t2; return z; }; var equidistantSampler_T1 = function ( t1 ) { t1 = Math.sqrt(t1); return t1; }; var equidistantSampler_T2 = function ( t2 ) { t2 = t2; return t2; }; freePlane(this, parametricPlane_X, parametricPlane_Y, parametricPlane_Z, equidistantSampler_T1, equidistantSampler_T2); this.computeCentroids(); }; THREE.FreeWallGeometry.prototype = Object.create( THREE.Geometry.prototype ); } ); </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.

SQuiL has stopped working due to an internal error.

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