Prepare a 3D Model for AR: Scale, Materials, and File Formats
A practical asset preparation workflow covering real dimensions, origins, materials, GLB and USDZ delivery, validation, and testing in the intended AR viewer.
Read the guideUse an extra dimension to answer a better question. Explore how models, materials, motion, and viewpoint turn complex shapes and relationships into something understandable.
3D visualization turns an object, arrangement, or system into a view you can explore. Rotating a model may reveal a hidden connection. A cutaway can expose an interior, while a sequence of views can explain how components move together. Each choice can make a particular relationship easier to see.
A useful visualization begins with the information people need. It can live on an ordinary screen, with immersive viewing added when the task benefits from it. This overview helps you choose the model, controls, and supporting explanation that give the extra dimension a clear purpose.
A typical 3D scene combines geometry, materials, object positions, and a camera viewpoint. Lighting and rendering determine how the scene appears on the display. Interactions then let a person change the view, select a component, or reveal an explanation.
Delivery formats help carry those elements between tools. glTF, for example, describes scenes, meshes, materials, and animation; its GLB container can bundle asset data for delivery. The exported result still needs review in the destination viewer, because an authoring viewport alone cannot establish how the public experience will behave.
Give each interaction a reason. Rotation helps inspect shape. Selective hiding can expose an internal relationship. A reset button restores orientation. A short animation can show a movement that would be difficult to infer from a still image.
Start with the action that reveals the essential information, and introduce additional controls only when they contribute. Keep labels consistent with the accompanying text. When a task depends on exact values, show the measurements directly so visitors can connect the visual impression to the underlying information.
A model may come from a design file, a scan, or manual construction. Describe its origin and identify relevant simplifications. Missing surfaces, altered proportions, exaggerated movement, and teaching colors can all influence interpretation. A reviewer should be able to tell what the model is intended to represent.
Performance also depends on the complete scene and destination device. Geometry, textures, materials, and animation can affect the workload. Evaluate a representative asset at the intended viewing distance and interaction level, then simplify according to what the viewer needs to see. Keep a useful static explanation available during loading or when interactive viewing fails.
Choose one subject and write a specific viewing task, such as identifying where a handle joins a body. Prepare a starting view that introduces the whole object, a closer view of the relationship, and a brief explanation of what matters.
Test the experience with someone unfamiliar with the model. Can they locate the feature and describe its significance? Use their answer to refine the presentation. Once that question is answered clearly, decide whether AR placement, a larger spatial scene, or further animation would support another useful task.
