I’m new to Babylon.js and hence I’m overwhelmed with the large amount of functionality and details in Babylon.js. I have a Birddog PTZ camera in front of a rounded greenscreen and this scene is 1:1 modeled in a basic 3D model inside Blender in order to project large images onto the rounded greenscreen in a natural fashion. I can successfully export the model from Blender to Babylon.js through glTF and when I use getCameraByName(), Babylon.js already correctly renders the scene as it is in Blender.
The Birddog PTZ camera now sends FreeD-based coordinates 30 times per second via UDP to a small server which I forward via WebSockets into my Babylon.js app. I now finally want the camera in Babylon.js to pan/tilt/zoom in sync with the physical Birddog PTZ cam, of course. The FreeD coordination system for pan/tilt has floats from -180 degree to +180 degree and for zoom it is a float in the range from 0 to 20. The questions to me now are:
(1) what optimal type of Babylon.js camera should I use for PTZ (e.g. DeviceOrientationCamera)?
(2) how can I convert the camera from getCameraByName() into this optimal target camera type?
(3) how do I translate the FreeD coordination system into the coordination system of the Babylon.js camera?
