Building VR projects in modules: start small, then expand

Building a virtual reality (VR) project in modules means starting small and then expanding step by step. This keeps costs under control, lets you build on experience from real-world use and allows you to reuse components. In this article, we explain why this approach pays off.

1. What is a modular structure?

Software can be structured in very different ways. You can develop it as a “monolith,” which gives you one large block of software. A monolithic application is usually not the result of a conscious decision. It is what happens when planning is poor, especially under time pressure. You may also find our article Why an ideation workshop is essential if you are planning a large virtual reality app interesting.

A modular structure takes extra planning and time. As we’ll see later, though, this investment pays off in almost every case. In modular software, small self-contained parts are developed, each forming a unit of its own. Once a unit is finished, it can be tested, optimized and released. Then the next module can be developed and combined with the first. Like a set of building blocks, the software is developed in pieces and “snapped together.”

2. Why build in modules?

2.1. Keeping costs under control

Building a VR project in modules helps you keep costs under control. Instead of developing a complex, full-scale solution right away, you start with a minimal version 1.0 that contains only the basic features. We especially recommend this if you don’t yet have much experience with virtual reality. That way, you initially invest less money in a basic first app and gain valuable experience in project development. When the app gets its next modules, you can plan and decide on a more solid basis.

2.2. Flexibility through updates

Another advantage of a modular structure is flexibility through updates. Because your VR software is developed in small, manageable units, you can add new features or adjust existing functions at any time without changing the entire app. That makes your project future-proof and lets you respond to new requirements or technologies.

2.3. Building on experience

If you put an app with a minimal feature set into use early on, you can build on the experience you gain as development continues. That is a big advantage over developing the full app from the start. You learn from user feedback and can keep improving your project.

2.4. Reusable functions

At VRtual X, we like to develop functions as packages. This means individual program components take a little more development time because they have to work across projects. In return, they are easy to reuse, which can save a lot of time and money in development. These packages can later be used in other projects, making your development more cost-effective.

3. Our recommendation

If you are planning a large VR application, start by developing the smallest possible unit. Test it in real-world use and apply what you learn to plan and commission the next modules. This keeps costs under control, lets you build the app step by step into a well-optimized full version and keeps you flexible for further development and changes. Reusable packages also save you time and money.
