Element Icon Old Random-dot motion
Category: Deprecated AddIn: Visual Kernels
Creator: OkazoLab Scope: Parent event
Owns Snippets: None Usage: Stimulus screen


NameDescription                              ConstraintsTypeOn
Dot Pattern
Dot Density        (%) The requested proportion of the all visible dots to the total number of dots in element's rendering area                Double         
Lookup Map Size        The size of the lookup map. Use value larger than the rendering area of the given element. Larger lookup map increase non-periodicity of the dot motion                clSize         
Allow Dot Clusters        Indicates whether clusters of two or more dots are allowed. If false, all visible dots will be isolated but the actual dot density may be decreased.                Boolean         
Lookup Index        Index of the random lookup map. If value is 0 then an automatic time dependent index is used. Otherwise, the value has to be a positive integer.                Int32         
Background color        Background color such that its brightness (B) is used to define the luminance of element's background                stColor         
Dot color        Foreground color such that its brightness (B) is used to define dot luminance                stColor         
Show Lookup Borders        Indicates whether the left and top borders of the lookup map are shown being superimposed over the dots. Use for debuging purposes.                Boolean         
Motion Coherence        (%) Proportion of the dots coherently moving in a single direction                Double         
Motion Step        The pixel distance of one step of the coherent motion. Can be less than 1 for slow motion                Double         
Motion Angle        Direction of the coherent motion in degrees (0..360).                Double         
Noise Lookup        Lookup position on the map A representing the noise dots                Point         
Motion Lookup        Lookup position on the map B containing coherently moving dots                Point         
Make Noise        Runtime action.                 Boolean         
Make Motion        Runtime action.                 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         
Rotation        Rotation angle in degrees                Double         
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         
Test Jitter        Click to test the current jitter                Boolean         
Is Enabled        If set to false the element is completely omitted when the experiment is run                Boolean         
Title        Title of the element                String         

Old Random-Dot Motion Element generates a sequence of 2D frames that can make up a random dot motion pattern. The selected fraction of all dots can be set to move in a single direction, thus producing a coherent motion. This element is deprecated, use Random Dot Motion element instead.
