3D & Spatial

Look for a readable silhouette, useful shadow detail and enough separation from the background. Adjust the camera and lights before relying on surface effects to provide all the interest.

Then test the actual materials. Glass, metal and translucent surfaces interact with light differently, so a neutral pass is a starting point rather than a final lighting solution. Refine reflections and highlights around the features the image needs to explain.

A familiar neighbour, a dimension label or a view of the object in use can provide context. Choose the reference that helps explain the object without competing with it.

Keep scene units consistent and check the relationships between objects. Camera position, framing and depth of field also influence the impression of scale. If accurate size is important, do not rely on visual cues alone: include dimensions or another explicit reference.

Begin with the feature or relationship you need to show, then choose the height, angle and distance that reveal it clearly.

Focal length changes the field of view; camera position changes perspective. Review them together instead of treating a lens choice as a shortcut to a particular mood. For an interactive model, provide a useful starting view and a way to return to it, while allowing the movement needed to inspect the object.

Geometry, textures, materials and lighting all contribute to that cost. Agree on the expected devices, network conditions and useful loading time before investing in detail.

Measure a representative scene early. Spend detail where it affects the silhouette or the intended close-up, and simplify what cannot be seen. File size alone does not predict runtime performance. Review memory use and responsiveness as well, and provide a useful fallback while the model loads or when it cannot run.
