Camera are structures used to render graphic objects (2D/3D). They thus can be referenced by other structures.

[CameraTemplate]
GroupList        = Group1 # ... # GroupN
GroupValue       = sort # raw
Zoom             = <float>
Position         = <vector>
Rotation         = <float>
FrustumNear      = <float>
FrustumFar       = <float>
FrustumWidth     = <float>
FrustumHeight    = <float>
ParentCamera     = CameraTemplate
IgnoreFromParent = none | all | rotation | scale<.xyz>

Here's a list of the available properties for an orxCAMERA structure:

• FrustumNear/FrustumFar: Defines the near and far planes for the camera frustum. The near plane is excluded whereas the far plane is included when doing render culling.
• FrustumHeight/FrustumWidth: As orx's cameras are 2D ones, their frustum are rectangle cuboids instead of real frustums. If you want to achieve a 1:1 aspect ratio with your main display window, you can use the Display.ScreenHeight and Display.ScreenWidth values.
• ParentCamera: If defined, this will set this camera as a child of the specified camera, in the same way it's done for orxOBJECTs that have a ParentCamera property.
• Position: Camera's initial position.
• Rotation: Camera's initial rotation (along its Z-axis).
• Zoom: Camera's initial zoom.
• GroupList: Groups (of objects) will be rendered in the order of declaration. Up to 16 groups can be associated to a camera. Defaults to “default” group. ^{1) 2)}
• GroupValue: If a group is set to “raw”, objects assigned to it will not be sorted before rendering, which allows for rendering very large amounts of objects at high performance *when* sorting isn't required. Defaults to “sort”.
