Question on scene animation and rotating scanners

[han16nah]

I would like to implement a simulation of an animated scene using a rotating scanner, where the scene is updated as the scanner head rotates. How can I do this with BLAINDER?
In my first attempts, each frame contained my entire scene.
What I want is for the first frame to scan the leftmost part of the scene, the next frame to scan the next section to the right, and so on.

It sounds like you did not configure your scanner correctly. The angle which is scanned in each frame is determined by the Frame rate parameter (frames per second) and the Rotations per second parameter (only visible when selecting the scanner type rotating) which can both be configured within the BlAInder interface.

You can calculate it yourself using: 360° * rotations per second / frames per second = angle per frame

For example:

• when your frame rate is 2 and your rotations per second is 1 then in each frame should scan 360° * 1 / 2 = 180°.
• when your frame rate is 24 and your rotations per second is 6 then in each frame should scan 360° * 6 / 24 = 90°.

You can have a look at the velodyne.blend file inside the examples directory which shows the use case of a rotating sensor. If that does not help you, could you provide me with a minimal reproducer example please?
