Editorial draft available to read. Factual and language review is pending. Examples are illustrative.
Define a specific purpose
Decide whether it explains a product, supports configuration or expresses identity. Do not assume all three. Define memorable meaning and space for branding; for demos, identify information interaction reveals more clearly than a still image.
Compare with a simpler option
Compare interactive and static versions with identical content. Review time to useful information, legibility and mobile behaviour, including model upkeep and fallback. Complexity needs visitor benefit rather than a demonstration of technical skill.
Accept bounded interaction
Example: rotating a part reveals a hidden connection; a decorative sphere does not. Keep primary controls usable and reduce motion when needed. Accept when the declared purpose works across representative devices and absence never blocks reading, comparison or contact.
Key takeaways
- Assess understanding, identity and interaction cost before adding visual complexity.
