Generic Properties

NameProperty descriptionConstraintsTypeUpon change
Camera Orbit
Orbit RotationRotation of the camera in the view-port orbital system. The field X,Y and Z represent Yew, Pitch and Roll in degrees. Vector3D
Orbit CenterCenter of the camera orbit in the world coordinates. Point3D
Orbit ScaleScale of the camera orbit height relative to the orbit center. The value is in percentates where 100% match to the default camera position in the current 3D model. Double
Camera Settings
Camera PositionCamera location in world coordinates. The property does not specify where the camera is directed. The direction is defined by the Camera Lookup Direction property. Point3D
Lookup DirectionVector3D which defines the direction in which the camera is looking in world coordinates. Vector3D
Camera Up DirectionUnit vector that that represents the upward direction of the camera and scene projection Vector3D
Near Plane DistanceDistance from the camera to the camera's near clip plane Double
Far Plane DistanceDistance from the camera to the camera's far clip plane Double
Field of viewHorizontal bounds of the camera's projection between the camera's position and the image planee, in degrees Double
Object tracking
Is TrackingEnables 3D reatime object tracking Boolean
Tracked ObjectName of 3D object which is currently tracked String
Tracked Point3D coordinate of the tracked point on the tracked object Point3D
Tracking DistanceDistance from the screen surfce to the tracked point of 3D object, in the world units Double

Alpha MaskingDefines whether the visual content rendered by this element will be used as an opacity mask which is applied onto the given event surface. The active opacity mask allows one to expose pixels of the parent event surface through a solid background of the given event. If the value is true, the darker pixels of the content will make more transparent holes on the entire event surface.Boolean
AntiAliasingIf true, the rendered content will be anti-aliased for smoother visual appearance. If false, rendering will be authentic to its source, e.g. a bitmap. Boolean
PositionDefines the position of the element viewport on the screen. The position can be set in any of three coordinate systems: a) pixels, b) polar, c) central. clPoint
SizeDefines the size of the element viewport on the screen. The size can be set in any of three coordinate systems: a) pixels, b) visual degrees, c) 'relative-to-screen' size. clSize
Z OrderIndicates the current depth order of the element viewport on the surface of the parent event. The greatest number corresponds to the top position. The order can be changed by moving the element up and down in the element list.Int32
Pivot PointDefines the pivot point (coordinate and the rotation centers) within the element viewport. stAlignment or Int32
VisibleDefines whether the element is currently visible on the event surface. The property is convenient for switching visual content on and off. Boolean
RotationDefines the rotation angle (in degrees) of element viewport relative to the its pivot point. Double in the range 0..360
Transparent ColorThe color of the original pixels of rendered content that will be set as transparent. stColor
Transparency ToleranceTolerance ratio for choosing colors that become transparent. Zero means that effect is not applied, 1 denotes that all colors will become trasparent. Int32, range (0..100)
Color MaskProduces a multiplicative combination of the original pixels and the selected mask color (except the alpha channel). The effect emulates a look through a colored glass. White or transparent mask color doesn't change the original pixels. stColor
OpacityOpacity of the rendered content. Int32, range (0..100)
ContrastContrast of the rendered content. Int32, range (-100..100)
BrightnessDefines the brighness of the rendered content. Int32, range (-100..100)
SaturationSaturation of the rendered content. Double
PixelationDefines the pixel scale of the rendering. Int32, range (0..100)
BlurringThe radius used in the gaussian blur of rendered content, as a pixel-based factor. The default is 0 which means no blurring. Int32
Reset JitterSet to true at runtime to reset the current positional jitter.Boolean, set true for action
Current JitterJitter range, in pixels (non inclusive)..clSize
Jitter RangeJitter range, centered at the original position of the element.. clSize

Material List
Selected IndexDefines the index of the active item in the material list of the element. Int32A change causes the current item to be reloaded and an update of the element.
Selected ItemDefines the name of the active item in the material list of the element. The name matches to a name of item in the Material Library StringA change causes the current item to be reloaded and an update of the element.
Item CountReturns the total number of items in the material list of the element.Int32
Equalize RGBThe property is only available in the visual element. If the value is true, the average RGB pixel intensity will be equalized across all items in the material list. You can turn on this property, when you need to obtain a luminance-balanced set of visual stimulus. Boolean

3D Viewport element allows rendering of 3D models stored in popular 3D formats, e.g. the Wavefront obj. The elements allows to control the camera position for changing 3D views or producing 3D animation. Multiple 3D scenes can be loaded into element's material list in order to form a 3D stimulus set. If you need even deeper control of 3D scenes, consider using another element, 3D XAML element, which requires model conversion to the XAML 3D format.
