Cameras
Cameras are another display type in the disguise software. Similarly to projectors they render the scene from a specific point of view and allow you to output that view using feed rectangles in the Feed editor.
The Visualiser's view of the stage is also a Camera called the Visualiser Camera. This can be accessed by clicking the Visualiser Camera button below the Cameras list or right clicking on the background.
Warning: Be aware that having multiple cameras requires part of the scene to be rendered multiple times so can incur a major performance cost.
-
Open the stage editor by right clicking stage from the dashboard or by right clicking the floor in the visualiser.
-
Expand the Cameras tab.
-
Click + to add a camera.
-
Left click the new camera field in the Camera manager.

You will now see a camera object in the visualiser, at the origin point (0,0,0).
-
Open the stage editor by right clicking stage from the dashboard or by right clicking the floor in the visualiser.

-
Position the camera in the visualiser.
-
Left click Feed from the dashboard.
-
Right click on the camera feed at the top of the feed scene and left click Add feed rectangle or alternatively hold ALT, left click and drag an arrow from the camera feed to an available output head.
The camera properties include the following categories:
-

Settings
The offset in meters of the camera’s position from its parent. When parented to the stage which is the default this is the camera’s world position.
The rotation transformation in degrees from its parent. When parented to the stage, which is the default, this is the camera’s world rotation.
See Object tracking source for more information.
Take from GUI - Default, Use the resolution of the GUI display.
Fixed - You can specify a custom resolution. Will not change the resolution of the display, only the camera's view.
The resolution that the camera will use to render its view.
The vertical field of view in degrees of the camera.
The horizontal field of view in degrees of the camera.
Preview
Sets the camera to Transmission, Backplate or Frontplate.
Toggles whether the camera will show Alpha or not.
Output
Opacity of the set extension.
Feather of the set extension. This is defined as the width of the feather.
Defines whether you have video input on or off. Helpful if you want to see how well the set extension is lined up.
AR content on or off. Frontplate content only. Helpful to see how well the AR content is lined up.
Applies a radial mask to the film content.
Backplate aligned
Front plate is delayed and reprojected with the backplate so frontplate and backplate content are displayed in sync. This is the default.
No reprojection
Frontplate is delayed along with the backplate content but is not reprojected. This is used for frontplate content that aligns more with the filmed content.
Minimal latency
Backplate image and frontplate images are taken from two different points in time. This results in the latest frontpate frame being displayed.
Defines how content assigned to frontplate is ordered in the composite stack.
Defines which LUT is applied to the camera. The disguise software has a number of LUT files built in.
Defines which colour profile the camera is. The disguise software has a number of colour profiles built in.
Hold output freezes the current frame of the camera output. This is a toggle setting.
Hierarchy
Shows the parent object (this is usually the stage, so the object will be offset from the origin point of the stage).
Shows children of the object.
Click Add child to create a parent/child relationship between this object and another.
Click Parent to stage to re-parent the object back to the stages origin point.
Stage Render
Anti aliasing can smooth out jagged edges caused by aliasing. The higher the number the smoother aliasing, but at more of a performance cost.
Changes the background colour of the scene. In schematic this will be the background colour.
In Lux this will be the base colour of the environment and is affected by lighting. For example if the ambient light is 0 the background will be black regardless of the colour.
In heatmaps the background is always black.
Luminance - Luminance - The intensity of light emitting from an object or surface per meter in a given direction, measured in nits (cd/m²)
Illuminance - The density of incident light in lumens hitting a surface per meter, measured in lux (lm/m²).
White point - Camera exposure in lux.
Ambient occlusion power - Power of the ambient occlusion effect in the lux renderer. 0 disables it.
Glow brightness - Impact of glow effect in lux renderer.
Any geometry closer than the near clipping plane or further than the far clipping plane will clipped (not be rendered). The values are in meters.
Reducing the range of these values can improve shadow quality and reduce shadow acne.
Used to temporarily disable rendering of faces with normals pointing to the front or to the back
Camera type
Perspective - Perspective view.
Orthographic - Orthographic view.
Orthographic Camera has no concept of depth and distance from the scene. A zoom-like effect can be achieved by adjusting the Orthographic Scale, but this setting is independent from Zoom in the equivalent Perspective Camera.
Visibility
Hidden (default) - hides measurements from view.
Visible - shows measurements in view.
Hidden - hides projector from the view
Beam - Shows projector beam only
Wire - Shows projector wireframe only
Beam and wire (default)- Shows projector beam and wireframe.
Projectors - Labels for projectors only.
Projection Surfaces - Labels for projection surfaces only.
LED Screens - Labels for LED screens only.
DMX Screens - Labels for DMX Screens only.
DMX Lights - Labels for DMX Fixtures only.
Props - Labels for props only.
Cameras - Turn on or off the visibility of Cameras.
Camera Labels - Labels for cameras.
Visible (default) - People are visible in the view.
Hidden - People are hidden from the view.
Visible (default) - Venue is visible in the view.
Hidden - Venue is hidden from the view.
Visible - Tracked points from Blacktrax are visible in the view.
Hidden (default) - Tracked points from Blacktrax are not visible in the view.
Visible - Tracked point labels are visible in the view.
Hidden (default) - Tracked point labels are not visible in the view.

Physical
Defines the live video input this camera is linked to.
Used as a reference to re-align filmed content when using virtual zoom.
Used to create spatial calibration configurations
Roundtrip latency time calculated from calibration process.
Amount of time in seconds between the camera frame arriving and the tracking data associated with it arriving. This is calibrated automatically.
Allows for adjustment to the time needed to sync between lens and tracking data.
Lens
Defines the overscan ratio. Default is 1. Setting to 1.1 would mean an overscan of 10%. The higher the overscan, the higher the performance impact.
Overscan resolution is the readout value in resolution of the overscan values.
This is a readout value of the final aspect ratio of the camera.
This is a readout value of the calculated focal length of the camera.
Defines the sensor width.
Offset of the focal point of the lens from the centre of the light sensor, measured in mm.
k1 - First order radial distortion coefficient, as measured.
k2 - Second order radial distortion coefficient, as measured.
k3 - Third order radial distortion coefficient, as measured.
Prediction
The amount of time between the disguise software outputting the frame and capturing the image. Prediction is turned off when this value is zero. If you want to turn prediction on, increase this value until the image looks good. Do not increase beyond the Video Receive Delay value.
How much of the history of the tracking data to predict into the future. Expressed in frames.
How many terms we used to model the movement. Two terms is linear. Three terms is a cubic prediction.
