How implement a walk-through or exploration feature for model (such as a "castle" model)

How can I implement a dynamic camera walkthrough functionality where the camera moves to specified positions around a 3D model and animates forward to explore the model? I want to define specific positions (waypoints) for the camera to move to, and use an animation to smoothly transition between these positions as the camera explores the model.

Hello,
To implement a dynamic camera walkthrough in a 3D model, you can define waypoints and use interpolation for smooth transitions. Here’s a basic approach using JavaScript and Three.js: mypoints login

  1. Define waypoints: Specify the camera positions (waypoints) you want to visit.
  2. Interpolate between waypoints: Use an animation loop to move the camera smoothly between waypoints.
  3. Update the camera position: Continuously update the camera’s position based on the interpolation.
