Virtual Reality

Virtual reality is a technology that immerses you in a completely computer-generated 3D environment through a head-mounted display. As you turn your head and move, the headset updates the view in real time so you feel present inside the virtual world. Controllers or hand tracking let you interact with objects in that space.

A VR headset shows each eye a slightly different image to create a convincing sense of depth, while sensors track your head and controller movements. Software running on the headset or a connected PC renders the environment and updates it instantly as you move, so the world feels stable and responsive. Keeping latency low and the frame rate high is what makes the experience comfortable.

Virtual reality replaces the real world entirely with a computer-generated environment seen through an opaque headset. Augmented reality instead overlays digital content onto your real surroundings, viewed through a phone or transparent display. VR is about full immersion in a new world, while AR adds to the world you are already in.

Real-time formats dominate VR because assets must load and render efficiently, so glTF and its binary form GLB are widely used, along with FBX for authoring inside engines. Models are typically imported into Unity or Unreal, which package them into the final VR application. Optimized, low-poly geometry with PBR textures is preferred to keep performance high.

Most VR experiences are built in a real-time game engine, with Unity and Unreal Engine being the two dominant choices, using their XR toolkits to target headsets like the Meta Quest. You assemble optimized 3D models, add interaction and locomotion, then build the project to run on the headset. The workflow is similar to game development, with extra attention to performance and comfort.

The core software, including Unity, Unreal, and their XR frameworks, is free to start with, and standalone headsets have made hardware far more affordable than early VR. The main challenge is technical: you must keep frame rates high and assets highly optimized, which demands solid 3D and programming skills. Simple experiences are achievable for hobbyists, while polished VR products take real expertise.

Standalone headsets like the Meta Quest are the most popular because they run untethered without a PC, while PC-driven headsets such as Valve Index deliver higher fidelity. Mixed-reality devices like Apple Vision Pro also offer immersive VR modes. The choice affects performance budgets, since standalone headsets have less processing power than a gaming PC.

VR renders the scene twice, once per eye, at high frame rates, so the performance cost is far greater than a normal single view. If assets are too heavy, the frame rate drops and users can feel motion sickness, which makes optimization critical. Artists rely on low-poly models, LODs, and efficient PBR materials to keep VR scenes smooth and comfortable.

Meshy generates textured, PBR-ready 3D models from text or images and exports GLB and other formats that import directly into Unity and Unreal. Its remesh feature lets you reduce a model to a low-poly, VR-friendly budget so scenes stay performant at the high frame rates headsets require. That lets you fill immersive environments with assets quickly instead of modeling each one by hand.
