public class Extrusion
extends Mesh

An extrusion of a 2D object (Line) along a path (List of Vector3). Either a convenience constructor can be used or the updateGeometry method. It is also capable of doing a cubic spline interpolation for a list of supporting points

Constructor Details

Extrusion

public Extrusion()

Default Constructor. Creates an empty Extrusion.

Extrusion

public Extrusion(String name)

Creates an empty named Extrusion.

Parameters:

name - name

Extrusion

public Extrusion(Line shape,
 List<ReadOnlyVector3> path,
 ReadOnlyVector3 up)

Convenience constructor. Calls updateGeometry.

Parameters:

shape - see updateGeometry

path - see updateGeometry

up - up vector

Extrusion

public Extrusion(String name,
 Line shape,
 List<ReadOnlyVector3> path,
 ReadOnlyVector3 up)

Convenience constructor. Sets the name and calls updateGeometry.

Parameters:

name - name

shape - see updateGeometry

path - see updateGeometry

up - up vector

Method Details

updateGeometry

public void updateGeometry(Line shape,
 List<ReadOnlyVector3> path,
 ReadOnlyVector3 up)

Update vertex, color, index and texture buffers (0) to contain an extrusion of shape along path.

Parameters:

shape - an instance of Line that describes the 2D shape

path - a list of vectors that describe the path the shape should be extruded

up - up vector

updateGeometry

public void updateGeometry(Line shape,
 List<ReadOnlyVector3> path,
 boolean closed,
 ReadOnlyVector3 up)

Update vertex, color, index and texture buffers (0) to contain an extrusion of shape along path.

Parameters:

shape - an instance of Line that describes the 2D shape

path - a list of vectors that describe the path the shape should be extruded

closed - true to connect first and last point

up - up vector

updateGeometry

public void updateGeometry(Line shape,
 List<ReadOnlyVector3> points,
 int segments,
 ReadOnlyVector3 up)

Performs cubic spline interpolation to find a path through the supporting points where the second derivative is zero. Then calls updateGeometry(Line, List, ReadOnlyVector3) with this path.

Parameters:

shape - an instance of Line that describes the 2D shape

points - a list of supporting points for the spline interpolation

segments - number of resulting path segments per supporting point

up - up vector

updateGeometry

public void updateGeometry(Line shape,
 List<ReadOnlyVector3> points,
 int segments,
 boolean closed,
 ReadOnlyVector3 up)

Performs cubic spline interpolation to find a path through the supporting points where the second derivative is zero. Then calls updateGeometry(Line, List, boolean, ReadOnlyVector3) with this path.

Parameters:

shape - an instance of Line that describes the 2D shape

points - a list of supporting points for the spline interpolation

segments - number of resulting path segments per supporting point

closed - true to close the shape (connect last and first point)

up - up vector
