These nodes read and change the size of a 3D object. Size is given as three numbers — X, Y, and Z — each a multiplier of the object’s original size: 1 means unchanged, 2 means twice as big, 0.5 means half. Most come in two forms: a world version that uses the ...

These nodes read and change how a 3D object is turned in your scene. An object’s rotation is given as three numbers — Pitch, Yaw, and Roll — measured in degrees (90 = a quarter turn). Most come in two forms: a world version that uses the object’s orientation i...

These two nodes let one participant in a shared VR session follow along with another — for example so a trainee can shadow an instructor, or an instructor can keep an eye on a trainee. Start with Observe User and end with Stop Observing. Observe User Lets...

Every object in your scene can carry extra pieces of information called attributes — small named values you attach to an object and read back later. Attributes can also be grouped into named categories, which lets one object keep separate attributes that share...

These nodes work with a part’s assembly state in a VR assembly. In SimLab’s assembly system a part moves through three stages — think of a screw: all the way out (fully disassembled), dropped into place but not tightened (partially assembled), or tightened all...

These are event nodes for SimLab’s VR assembly system. Each one watches a single part and fires the moment something happens to that part in the assembly — for example the moment it becomes fully assembled, or the moment it becomes this part’s turn to be put o...

SceneState Applied Reacts the moment a saved scene state is switched on in your scene. What it does A scene state is a saved arrangement of your scene — which objects are shown or hidden, where they sit, the materials they use, and so on. This node watches...

Nodes for working with variables — the named values your scene keeps and reuses, each holding a number, a piece of text, or a time. Cast Variable Checks whether a variable holds the kind of value you expect, and only passes it along when it does. What it ...

These events fire when a user picks up or lets go of a scene object in VR. Use them to react the moment an object is grabbed or released — for example to highlight a tool when it is held, or reset it when it is put down. Each event also tells you which user ...

These events fire when a user points at or moves away from a scene object in VR (without grabbing it). Use them to react as an object is hovered — for example to highlight it, show a label, or hide that hint again when the user looks elsewhere. Each event also...

These events fire in response to what a playing sequence does, so you can react automatically when a sequence reaches a key moment — without having to start the check yourself. Sequence events Sequence Ended This node lets your scene react the moment a s...

These events watch a true/false value and fire the moment it changes — so you can start something the instant a condition becomes true, becomes false, or simply flips either way. They never change the value they are watching; they only react to it. Boolean ...

The Dynamic Cloud Attribute nodes save and read small pieces of text in SimLab’s cloud, so a VR experience can remember information between sessions and across devices — a person’s progress, a saved choice, a score, and so on. They are the flexible counterp...

The VR Assembly System in SimLab Composer provides an intuitive, code-free framework to design step-by-step 3D disassembly and reassembly procedures for Virtual Reality and interactive 3D desktop environments. By using a visual node graph, you can map out exac...

Complex mechanical equipment often requires more than simple individual part removal. SimLab Composer allows you to group components into sub-assemblies and create custom components controlled through the Training Builder to handle specialized tools like beari...

When building mechanical assembly diagrams in SimLab Composer, different components require different rules for when they can be detached. Dependency Modes dictate whether a part requires all preceding connected components to be removed first or if removing an...

The Web Browser VR node shows a web page on a plane in the VR viewers. When you set its Source to HTML, you type the page in Composer, and the viewers load that text as the page. The viewers add a set of JavaScript functions to the page's window. A page from S...

A quiz is a set of questions you build with the VR Quiz tool in SimLab Composer — multiple-choice, object-picking or star-rating questions, with an optional time limit. The node on this page shows a quiz to the trainee during the experience. To react to what t...
