6.2. Principle function diagram
The following pattern demonstrates how data is processed.
If you connect the grandMA VPU to a grandMA2 desk you can compare the result with some slide projectors
remote controlled by an MA desk.
In contrast to a slide projector the slides are not projected on the screen.
The screens or 3D objects are active light emitters like monitors and can take the shape of any geometric form.
This takes place on so called “layers”. Each layer output feeds a virtual camera.
The virtual camera outputs can be mixed up to a resulting video output.
Each layer has its own magazine containing emitting 3D objects.
Each layer has its own magazine containing videos, images and masks.
The number of 3D video layers can vary in dependence of the complexity of your show.
You can patch up to 32 layers
If the grandMA VPU is invited in a session by the desk, layers behave similar to a fixture. All layers have access to
the same content pool.
The application receives the amount of layers and each layer magazine is assembled with several images and
videos.
These are indicated by their relative paths and names.
If a layer 3D object or the content of a magazine is changed within grandMA VPU, the changed properties are
immediately taken up by the desk.
Several grandMA VPU applications are shown in several 'fixture layers’ on the MA-desk.
The following diagram shows a principle structure with 4 layers.
