    <p>I've created a webgl animation using the scenejs framework. As it'll contain a lot of identical elements, I want to minimize the amount of code used and re-use the elements as much as possible.</p> <p>Firstly, I've got diskJSON defined as following:</p> <pre><code>var diskJSON = [{ type: "disk", radius: 3, inner_radius: 2}]; </code></pre> <p>When I run the following code with sceneJS, it works fine.</p> <pre><code>{ type: "material", emit: 0, baseColor: { r: 0.3, g: 0.3, b: 0.9 }, specularColor: { r: 0.9, g: 0.9, b: 0.9 }, specular: 0.9, shine: 100.0, nodes: [ { type: "translate", x:10, y:1, nodes: [ { type: "translate", z:speedMultiplier*0.8, nodes:[{ type: "disk", radius: 3, inner_radius: 2 }] }, { type: "translate", z:speedMultiplier*9.8, nodes:[{ type: "disk", radius: 3, inner_radius: 2 }] }, { type: "translate", z:speedMultiplier*11.64, nodes:[{ type: "disk", radius: 3, inner_radius: 2 }] }, { type: "translate", z:speedMultiplier*13.32, nodes:[{ type: "disk", radius: 3, inner_radius: 2 }] } ] } ] } </code></pre> <p>However, when I try to reuse the same diskJSON as defined previously, it only creates one node, instead of 4:</p> <pre><code>{ type: "material", emit: 0, baseColor: { r: 0.3, g: 0.3, b: 0.9 }, specularColor: { r: 0.9, g: 0.9, b: 0.9 }, specular: 0.9, shine: 100.0, nodes: [ { type: "translate", x:10, y:1, nodes: [ { type: "translate", z:speedMultiplier*0.8, nodes:diskJSON }, { type: "translate", z:speedMultiplier*9.8, nodes:diskJSON }, { type: "translate", z:speedMultiplier*11.64, nodes:diskJSON }, { type: "translate", z:speedMultiplier*13.32, nodes:diskJSON } ] } ] } </code></pre> <p>The application will have thousands of these nodes, so having to redefine it every single time seems quite a waste. Is this a problem with scenejs or is this working as intended in regards to Javascript/JSON functionality? </p>

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.
