Constructor Details

TrailMesh

public TrailMesh(String name,
 int nrTrailSections)

Creates a new TrailMesh.

Parameters:

name - Name of Spatial

nrTrailSections - Number of sections the TrailMesh should consist of. Number of vertices in the mesh will be nrTrailSections * 2.

Method Details

setTrailFront

public void setTrailFront(Vector3 position,
 float width,
 float tpf)

Update the front position of the trail.

Parameters:

position - New position of the trail front

width - Width of the trail

tpf - Current time per frame

setTrailFront

public void setTrailFront(ReadOnlyVector3 position,
 ReadOnlyVector3 tangent,
 double width,
 double tpf)

Update the front position of the trail.

Parameters:

position - New position of the trail front

tangent - Specifies the gradient of the trail (if facingmode is set to tangent)

width - Width of the trail

tpf - Current time per frame

update

public void update(ReadOnlyVector3 camPos)

Update the vertices of the trail.

Parameters:

camPos - Camera position used for billboarding.

invalidate

public void invalidate()

resetPosition

public void resetPosition(ReadOnlyVector3 position)

write

public void write(OutputCapsule capsule)
           throws IOException

Specified by:

write in interface Savable

Overrides:

write in class Mesh

Parameters:

capsule - the capsule

Throws:

IOException - Signals that an I/O exception has occurred.

See Also:

• Savable.write(OutputCapsule)

read

public void read(InputCapsule capsule)
          throws IOException

Specified by:

read in interface Savable

Overrides:

read in class Mesh

Parameters:

capsule - the input capsule

Throws:

IOException - Signals that an I/O exception has occurred.

See Also:

• Savable.read(InputCapsule)

setUpdateSpeed

public void setUpdateSpeed(float updateSpeed)

getUpdateSpeed

public float getUpdateSpeed()

setUpdateMode

public void setUpdateMode(TrailMesh.UpdateMode updateMode)

getUpdateMode

public TrailMesh.UpdateMode getUpdateMode()

setFacingMode

public void setFacingMode(TrailMesh.FacingMode facingMode)

getFacingMode

public TrailMesh.FacingMode getFacingMode()

getTrailData

public LinkedList<TrailMesh.TrailData> getTrailData()

Get the mesh data to modify it manually. If data is modified, invalidate() method call is required.

Returns:

the mesh data
