Interactive 3D presentations and linear video demos differ primarily in user control and engagement: 3D enables active interaction, while video offers passive, fixed viewing.
- **User control**: 3D lets users manipulate content (e.g., rotate models, zoom into details), tailoring exploration to their needs. Video follows a pre-edited sequence with no user input. - **Engagement style**: 3D fosters dynamic, personalized engagement, ideal for highlighting specific product features. Video delivers consistent storytelling, suited for narrative-driven demos.
In short, 3D suits interactive, user-led exploration; video works for structured, passive storytelling.
