3D Perspective Camera - PRG MBOX User Manual

The Mix Mode parameter is used to modify how a layer's rendering is affected by the mix. The mix's size, position, and
rotation can all be taken into effect and used to modify the layer. There are 29 mix modes in total, with each mode being
a combination of one or more of the flowing properties:
+ Cropping - the layer's content may be cropped to the boundary of the mix. If enabled, the content may be manually
moved (X or Y position parameter) or scaled (overall scale and/or X and Y scale parameters) but will only ever be
visible inside the mixes boundaries.
+ Centering - the layer's content may be centered in the center of the mix. If enabled, the content may be manually
moved and that will act as an offset from the center of the mix.
+ Fit H - the layer's content will be scaled up or down to fit the width of the mix. The width of a rotated mix is different
to the width of the same mix if it were not rotated; it's the distance between the two opposite corners. If enabled,
the content can be scaled, and that will act as an offset from the automatic horizontal fit scaling. The aspect ratio of
the content will not be affected.
+ Fit V - the layer's content will be scaled up or down to fit the height of the mix. The height of a rotated mix is
different to the height of the same mix if it were not rotated; it's the distance between the two opposite corners. If
enabled, the content can be scaled, and that will act as an offset from the automatic vertical fit scaling. The aspect
ratio of the content will not be affected.
+ Fit H and V - a combination of the above two properties. However, in this case, the aspect ratio of the content may
be affected.
+ Rotate - the layer's content will be rotated to match the rotation of the mix. If enabled, the content can be manually
rotated using the Z rotation parameter, and that will act as an offset from the automatic rotation.

3D Perspective Camera

All three versions of Mbox have a default 3D camera that allows a basic, straight-ahead, perspective view of 3D objects
within Mbox's 3D environment. This default 3D camera is permanently assigned to the global surface (Mix 0) and is not
configurable.
However, in Mbox Designer, one or more 3D cameras can be added and configured:
+ Outputs can have a live-controlled (from Director or lighting console) "DMX Camera" if an output master is assigned
to the output.
+ Any mix (including outputs) can have a 3D camera applied to it using the Mbox Remote Projection Editor toolset.
These 3D cameras can only be adjusted from within Mbox Remote
+ It is possible to switch an output's 3D camera back and forth between a live DMX camera and a static camera
configuration created in Mbox Remote.
Typically, 3D cameras will be used on outputs when projection mapping, but it is possible to create and configure a 3D
camera for various compositional purposes.
Note: In Mbox Studio and Mini, only the global surface has a 3D camera.
In the default state, none of Mbox's mixes have a 3D camera assigned to them, except for the global surface. In this
state it is possible to use 3D objects and to see them in perspective, with the center of 3D space being the center of
the global surface and the camera's view being centered on the center of the global surface. Objects on layers can be
moved and the camera's view of them will change perspective as the objects move. However, in this default state, the
position, look-at point, and properties of the camera are preset and cannot be changed.
