How to place a dynamic visualization camera

Hi,

I am trying to create a simple simscape scenario of 2 moving vehicles. We need to extract the video from a dynamic visualization camera which is supposed to be fixed with one vehicle and moving along with it to capture the motion of the 2nd vehicle. Please help with the following.

Query-1) While creating dynamic camera, we referred to the example "sm_vehicle_slalom". But its not clear how to set the dynamic camera properly. While trying to create a camera for my program, in the 'camera manager' under the 'new camera' option for 'tracking' mode, its mentioned "Incomplete camera definition. Frame selections cannot be empty. Select a frame for each parameter to resolve this issue.". How to add the frame information to the camera.

Thanks

I understand that you want to know about how to add frame information to the camera while creating a dynamic camera.

To add frame information to the camera, the key step is to use frame objects and configure the camera's view targets to focus on those frames. This way, the camera will capture the frames as specified during simulation.

Complete the camera definition by selecting the camera mode and specifying the camera motion. See:

• Define a Keyframes Camera to define the camera motion in Keyframes mode. Keyframes are viewpoints that you specify at various playback times and that Simscape™ Multibody™ software interpolates to obtain smooth camera trajectories.
• Define a Tracking Camera to complete the camera definition in Tracking mode. Tracking constraints include position, aim, and up vector constraints that you specify relative to coordinate frames in a model.
