View Edit History Print PDF ## Set of surfaces (3D) A set is just an empty element, that can host other elements (and sets). As such, a set has a position and a size, and accepts a transformation, but you need to add other elements to the set to make it display anything on the panel. The great advantage of sets is that they allow manipulation of collections of other drawables as a whole. ## Properties
SurfaceSet3D
Number of elements
Name | Description | Values accepted | Default
#Elements | The number of elements in the set. | An integer value. |
Input
Name | Description | Values accepted | Default
Data | The double[nu][nv][3] data for the points of the surface. | A double array, double[][][]. Use a double[][][][] array for several elements. |
Position and Size
Name | Description | Values accepted | Default
Pos X | The X coordinate for the element. | A constant or variable of type double,int or double[]. |
Pos Y | The Y coordinate for the element. | A constant or variable of type double,int or double[]. |
Pos Z | The Z coordinate for the element. | A constant or variable of type double,int or double[]. |
Position [] | The double[] array with the coordinates of the element. | A matrix with double values. |
Size X | The size of the element in the X direction. | A constant or variable of type double or int. |
Size Y | The size of the element in the Y direction. | A constant or variable of type double,int or double[]. |
Size Z | The size of the element in the Z direction. | A constant or variable of type double,int or double[]. |
Size [] | The double[] array with the size of the element in each coordinate. | A matrix with double values. |
Transform | The transformation to apply to this element. | Use the editor provided or read more about transforms. |
Visibility and Interaction
Name | Description | Values accepted | Default
Visible | The visibility of the element. | A boolean variable or a boolean array with true or false values. |
Draggable | Whether the element can be moved. | A boolean variable or a boolean array with true or false values. |
Drag Group | Whether dragging the element affects its group. | A boolean variable or a boolean array with true or false values. |
Element | The index of the element affected by the interaction. | An integer value. |
On Press | The action to invoke when the element is pressed. | The Java code to invoke for the action. |
On Drag | The action to invoke when the element is dragged. | The Java code to invoke for the action. |
On Release | The action to invoke when the element is released. | The Java code to invoke for the action. |
On Enter | The action to invoke when the mouse enters the element. | The Java code to invoke for the action. |
On Exit | The action to invoke when the mouse leaves the element. | The Java code to invoke for the action. |
Graphical Aspect
Name | Description | Values accepted | Default
Line Color | The color used for the lines of the element. | Use the editor provided or read about colors. In this case you can use an Object[] to choose a different color for each element of the set. |
Fill Color | The color used to fill the element. | Use the editor provided or read about colors. The special value null draws a hollow element. Use an array to assing a color to each element. |
Line Width | The thickness for the lines of the element. | A constant or variable of type double or int indicates the thickness. | 1
Draw Lines | Whether to draw the lines. | A boolean variable or one of the constants true or false. |
Draw Fill | Whether to fill the element. | A boolean variable or a boolean array with true or false values. |
Resolution | The resolution with which to display the element. | A 3DResolution, a string, an Object or Object[]. In this case you can use an Object[] to choose a different resolution for each element of the set. |
