Class NavigationControl

java.lang.Object
  hmi.environment.NavigationControl

All Implemented Interfaces:

GLRenderObject, ClockListener

public class NavigationControl
extends Object
implements ClockListener, GLRenderObject

A simple form of keyboard based NavigationScene module. Keys: A and D move left and right, W and S move back and forth, Left and right "arrow" keys rotate, Up and down "arrow" keys move back and forth. PageUp and PageDown move up and down. One can pass required keymodifiers KeyEvent.VK_CONTROL/VK_ALT/VK_SHIFT at construction time

                         VJoint viewpoint,
                         boolean invert,
                         int[] keyModifiers)

Creates a new NavigationScene, listening to Component c for key and mouse events

public void setVelocities(float vel)

setLinearVelocity

public void setLinearVelocity(float vel)

setVerticalVelocity

public void setVerticalVelocity(float vel)

glInit

public void glInit(GLRenderContext gl)

OpenGL initialization.

Specified by:

glInit in interface GLRenderObject

glRender

public void glRender(GLRenderContext gl)

OpenGL rendering.

Specified by:

glRender in interface GLRenderObject

setPosition

public void setPosition(float[] pos)

set the position vector

setPosition

public void setPosition(float x,
                        float y,
                        float z)

getPosition

public float[] getPosition()

setOrientation

public void setOrientation(float xrot,
                           float yrot,
                           float zrot)

set the three Euler angles

getOrientation

public float[] getOrientation()

correctModifiers

private boolean correctModifiers(KeyState keyState)

Returns true if the keystate contains exactly those modifiers with which this control was initialized

initTime

public void initTime(double currentTime)

Description copied from interface: ClockListener

initTime() is called before the Clock starts running, and sends some initial time value. This will often equal the time send for the first regular time() call. This is done on the same clock Thread that is going to send the regular time() calls.

Specified by:

initTime in interface ClockListener

time

public void time(double currentTime)

Every clock tick, - check the new movements from the keystate, depending on the pressed keys - update the position and orientation of the controlled object

Specified by:

time in interface ClockListener

setRollPitchYaw

public void setRollPitchYaw(float roll,
                            float pitch,
                            float yaw)

setTranslation

public void setTranslation(float tx,
                           float ty,
                           float tz)
