Method Detail

init

public void init()

Initialization.

Overrides:

init in class PjProject

start

public void start()

Initializes display, geometries.

Overrides:

start in class PjProject

Specified by:

update in interface PsUpdateIf

Overrides:

update in class PsObject

Parameters:

event - carries a lot of information

Returns:

true if event has been handled, otherwise false

pickVertex

public void pickVertex(PgGeometryIf geom,
              int picked,
              PdVector pickedVertex)

Drags a picked vertex of m_trunk.

Specified by:

pickVertex in interface PvPickListenerIf

Overrides:

pickVertex in class PjProject

Parameters:

geom - Picked geometry on which vertex lies

picked - Index of picked vertex in vertex array of geometry

pickedVertex - 3d coordinates of vertex position

PvPickListenerIf

getAge

public int getAge()

Returns the age of the tree which is the number of consecutive branches.

Returns:

the age of the tree.

setAge

public void setAge(int age)

Sets the age of the tree which is the number of consecutive branches. Main allocation method, allocates tree element set.

Parameters:

age - New age of the tree.

isEnabledRightTriangle

public boolean isEnabledRightTriangle()

Returns true if the triangle above trunk is kept right.

Returns:

true if the triangle is kept right.

setEnabledRightTriangle

public void setEnabledRightTriangle(boolean bRightTriangle)

Determines if the triangle above trunk is a right triangle.

Parameters:

bRightTriangle - use right triangle above trunk

isEnabledSquareTrunk

public boolean isEnabledSquareTrunk()

Returns true if the trunk is kept square.

Returns:

true if the rectangle is kept square.

setEnabledSquareTrunk

public void setEnabledSquareTrunk(boolean bSquareTrunk)

Determines if the trunk should be a square.

Parameters:

bSquareTrunk - use square trunk
