The useful points.
- Use video when the audience needs to see a specific sequence quickly.
- Use interactive 3D when different viewpoints are central to the discussion.
- Agree devices, hosting and access duration before commissioning a walkable experience.
Use a film for a guided explanation
A short video can introduce a site, follow a sequence and pause on an important detail without requiring the viewer to learn controls. It fits meetings, proposal decks and selected marketing channels. Its limitation is the fixed viewpoint: a question about the far side of an object may require another shot or a different deliverable.
Distinguish an object viewer from a walkable scene
A browser object viewer typically lets someone orbit and inspect a supported model. A walkable environment adds navigation through a larger space and can include selected object inspection or sequence controls when scoped. These require different preparation and delivery. Calling both “interactive 3D” without explaining the interaction can create the wrong expectation.
Plan around the viewing conditions
Ask who will open the experience, whether they can install software, which devices they use and whether reliable connectivity is available. A hosted live 3D environment can move rendering work to remote hardware, but access arrangements and running costs must be considered. A desktop application and a streamed browser session are different ways of delivering the same scene.
- For an introductory email, consider a still image or short video first.
- For a scheduled review, consider a guided walkthrough with agreed controls.
- For repeated inspection, define what needs to remain accessible and for how long.
Give viewers a clear starting point
Freedom to move is useful only when the visitor can find the subject. Define an opening viewpoint, concise controls and a way to return to the overview. If selected objects have inspection panels, agree which measurements or details are displayed and where those values come from. The experience should explain the proposal, not turn finding it into a task.
Commission the smallest complete experience
Begin with one clearly defined scene and the interactions required for the discussion. A supporting video can introduce the space before a live exploration. Agree the environment, controls, supported platforms, review rounds and hosting separately. Vekt’s public workspace samples show aspects of the client interface; they are not a promise that every project includes a live streamed environment.
