NameDescription                              ConstraintsTypeOn
colspan="5" bgcolor="#AADDDDD" |   
Reset Trajectory        Represents the command that resets the current trajectory list                Boolean         
Save Trajectory        Represents the command that saves the current trajectory list into a datafile                String         
Add Regular Keyframe        Represents the command that adds a new keyframe to the current trajectory list. The keyframe time is defined by 'New Keyframe Time' property                Boolean         
Add Blank Keyframe        Represents the command that adds a new blank keyframe (zero position and size) to the current trajectory list. The keyframe time is defined by 'New Keyframe Time' property                Boolean         
New Keyframe Time        Defines a local event time for the new trajectory keyframe                clTime         
Keyframe Pace                        Double         
Trajectory Control
Preview Trajectory                        Boolean         
Export To Library                        Boolean         
Visual Appearance
Alpha Masking        Defines, whether the visual content is used to create an opacity mask on the event surface. If masking is on, the content's pixel luminance (or, its inverse) defines transparency within element's viewport. The alpha masking allows, for example, create transparent holes on the event surface.                Int32         
AntiAliasing        if true, the rendered content will be antialiased for smoother visual appeariance. If false, rendering will be authentic to its source, e.g. a bitmap.                Boolean         
Position        Defines a position of the rendering viewport on the screen                clPoint         
Size        Defines a size of the element's rendering viewport on the screen                clSize         
Z Order        Indicates Z Order of the element on the given event                Int32         
Pivot Point        Defines alignment of the pivot point (or, element's position) relative to element's rendering area. The pivot point sets the center of element's rotation and scale directions.                stAlig..         
Visible        Defines whether the element is visible                Boolean         
Transparent Color        The color of the original pixels of rendered content that will be set as transparent                stColor         
Transparent Tolerance        Tolerance ratio for choosing colors that become transparent. Zero means that effect is not applied, 1 denotes that all colors will become trasparent                Int32         
Color Mask        Produces 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 dont change the original pixels                stColor         
Opacity        Opacity of the rendered content                Int32         
Contrast        Contrast of the rendered content                Int32         
Brightness        Brightness the rendered content                Int32         
Saturation        Saturation of the rendered content                Double         
Pixelation        Pixelation of the rendered content                Int32         
Blurring        The radius used in the gaussian blur of rendered content, as a pixel-based factor. The default is 0 which means no blurring.                Int32         
Scrambling                        Double         
Scrambling Grid Size        Defines a size of the scrambling grid                clSize         
Positional Jitter
Reset Jitter Now        Runtime command that resets the positional jitter.                Boolean         
Current Jitter        Returns the current jitter                clPoint         
Jitter Range        Defines a possible range for the random jitter. The range is centered to the position of the element.                clSize         
Is Enabled        If set to false the element is completely omitted when the experiment is run                Boolean         
Title        Title of the element                String         

Trajectory Builder Element assists in building a custom trajectory data set, which are made of keyframe list. The element allows to create a keyframe defined by the position and size of the element's viewport and export the resulting trajectory into Material Library or datafile. The element can be used at design-time only.
