Encapsulates creation of a series of connected or disconnected line segments or points, for drawing paths or rays.
This class doesn't attempt to be the smartest it could possibly be; it's intended primarily as a visualization and editing tool.
| LineSegs | ( | string | name | ) |
Constructs a LineSegs object, which can be used to create any number of disconnected lines or points of various thicknesses and colors through the visible scene.
After creating the object, call move_to() and draw_to() repeatedly to describe the path, then call create() to create a GeomNode which will render the described path.
| LineSegs | ( | ) |
Constructs a LineSegs object, which can be used to create any number of disconnected lines or points of various thicknesses and colors through the visible scene.
After creating the object, call move_to() and draw_to() repeatedly to describe the path, then call create() to create a GeomNode which will render the described path.
Appends to an existing GeomNode a new Geom that will render the series of line segments and points described via calls to move_to() and draw_to().
The lines and points are created with the color and thickness established by calls to set_color() and set_thick().
If dynamic is true, the line segments will be created with the dynamic Geom setting, optimizing them for runtime vertex animation.

| drawTo | ( | float | x, |
| float | y, | ||
| float | z | ||
| ) |
Draws a line segment from the pen's last position (the last call to move_to or draw_to) to the indicated point.
move_to() and draw_to() only update tables; the actual drawing is performed when create() is called.
| drawTo | ( | VBase3 const | v | ) |
Draws a line segment from the pen's last position (the last call to move_to or draw_to) to the indicated point.
move_to() and draw_to() only update tables; the actual drawing is performed when create() is called.
| Point3 const getCurrentPosition | ( | ) |
Returns the pen's current position.
The next call to draw_to() will draw a line segment from this point.
| int getNumVertices | ( | ) |
Returns the total number of line segment and point vertices generated by the last call to create().
The positions of these vertices may be read and adjusted through get_vertex() and set_vertex().
Returns the nth point or vertex of the line segment sequence generated by the last call to create().
The first move_to() generates vertex 0; subsequent move_to() and draw_to() calls generate consecutively higher vertex numbers.

| bool isEmpty | ( | ) |
| moveTo | ( | VBase3 const | v | ) |
Moves the pen to the given point without drawing a line.
When followed by draw_to(), this marks the first point of a line segment; when followed by move_to() or create(), this creates a single point.

| float | z | ||
| ) |
Moves the pen to the given point without drawing a line.
