Vtk-based 2D mapper for PointSet.
Due to the need of different colors for selected and unselected points and the facts, that we also have a contour and labels for the points, the vtk structure is build up the following way:
We have three PolyData, one selected, and one unselected and one for a contour between the points. Each one is connected to an own PolyDataMapper and an Actor. The different color for the unselected and selected state and for the contour is read from properties.
This mapper has several additional functionalities, such as rendering a contour between points, calculating and displaying distances or angles between points.
Point Representation
The points are displayed as small glyphs of configurable shape (see property "PointSet.2D.shape"). The size of these glyphs is given in world units. That means, the size or shape of those glyphs is independent of the BaseGeometry object that you assign to the PointSet. As for all other objects, positions of points will be transformed into the world via the Geometry's index-to-world transform.
Then the three Actors are combined inside a vtkPropAssembly and this object is returned in GetProp() and so hooked up into the rendering pipeline.
Applicable Properties
Properties that can be set for point sets and influence the PointSetVTKMapper2D are:
- "line width": (IntProperty 2) // line width of the line from one point to another
- "point line width": (IntProperty 1) // line width of the cross marking a point
- "point 2D size": (FloatProperty 6) // size of the glyph marking a point (diameter, in world units!)
- "show contour": (BoolProperty false) // enable contour rendering between points (lines)
- "close contour": (BoolProperty false) // if enabled, the open strip is closed (first point connected with last point)
- "show points": (BoolProperty true) // show or hide points
- "show distances": (BoolProperty false) // show or hide distance measure
- "distance decimal digits": (IntProperty 2) // set the number of decimal digits to be shown when rendering the distance information
- "show angles": (BoolProperty false) // show or hide angle measurement
- "show distant lines": (BoolProperty false) // show the line between to points from a distant view (equals "always on top" option)
- "layer": (IntProperty 1) // default is drawing pointset above images (they have a default layer of 0)
- "PointSet.2D.shape" (EnumerationProperty Cross) // provides different shapes marking a point 0 = "None", 1 = "Vertex", 2 = "Dash", 3 = "Cross", 4 = "ThickCross", 5 = "Triangle", 6 = "Square", 7 = "Circle", 8 = "Diamond", 9 = "Arrow", 10 = "ThickArrow", 11 = "HookedArrow", 12 = "Cross"
- "PointSet.2D.fill shape": (BoolProperty false) // fill or do not fill the glyph shape
- "Pointset.2D.distance to plane": (FloatProperty 4.0) //In the 2D render window, points are rendered which lie within a certain distance to the current plane. They are projected on the current plane and scaled according to their distance. Point markers appear smaller as the plane moves away from their true location. The distance threshold can be adjusted by this float property, which ables the user to delineate the points that lie exactly on the plane. (+/- rounding error)
Other Properties used here but not defined in this class:
- "selectedcolor": (ColorProperty (1.0f, 0.0f, 0.0f)) // default color of the selected pointset e.g. the current point is red
- "contourcolor" : (ColorProperty (1.0f, 0.0f, 0.0f)) // default color for the contour is red
- "color": (ColorProperty (1.0f, 1.0f, 0.0f)) // default color of the (unselected) pointset is yellow
- "opacity": (FloatProperty 1.0) // opacity of point set, contours
- "label": (StringProperty nullptr) // a label can be defined for each point, which is rendered in proximity to the point
