Support for Multiple TLS Platforms in a Single Survey

[saidharb]

Issue
To capture all surfaces of an object (e.g., a cube), I need to simulate different scanner orientations — vertical for the side faces, and tilted down/up to scan the top and bottom. I successfully defined custom platforms with specific scanner mount rotations in platforms.xml (e.g., rot axis="x" angle_deg="-90"), but encountered a limitation: surveys currently support only a single platform. This means all scanner positions within a survey inherit the same orientation, making it impossible to use different orientations within one survey.

Request
I would like to request support for assigning different platforms (with different scanner mount configurations) to individual legs or scanner positions within a single survey. This would greatly enhance the flexibility and efficiency of scene design and scanning simulation in HELIOS++.

Current Workaround
As advised from the HELIOS++ team, the current workaround is to:

• Define multiple platforms with the required scanner mount rotations.
• Split the simulation into multiple sub-surveys, each using a different platform.

While this works, it's not ideal in terms of usability or integration with automated dataset generation workflows.

Thank you for considering this request.

Best regards,
