Detailed Description

the FixedAxis Camera Controller is used to control the camera position and orientation in relation to a pivot point where the rotations generated are around the fixed axis of the world.

More specifically the horizontal mouse drag rotates the scene around the world z-axis whereas the vertical drag movements rotate the scene around the camera y-axis located in the pivot point.

Member Function Documentation

draw()

void draw ( )

virtual

draw the camera control.

Implements CameraController.

getCenter()

rw::math::Vector3D getCenter ( )

inlinevirtual

get the current pivot point in world coordinates

Returns

current pivot point

Implements CameraController.

getTransform()

rw::math::Transform3D getTransform ( ) const

virtual

get the current world to camera transformation

Returns

world to camera transformation

Implements CameraController.

handleEvent()

virtual void handleEvent ( QEvent *  event )

virtual

event handler, typically mouse and keyboard

Parameters

event

[in] the specific event

Implements CameraController.

setBounds()

void setBounds	(	GLfloat	NewWidth,

set the bounds that define the area where the 2d point is valid. The bound is defined in a plane with [0,width] and [0,height]. Where (0,0) is the upper left corner of the plane.

Parameters

NewWidth	[in] width
NewHeight	[in] height

setCenter()

void setCenter ( const rw::math::Vector3D<> &  center, const rw::math::Vector2D<> &  screenCenter  )

virtual

update the center of rotation and screen center

Parameters

center	[in] center of rotation in world coordinates
screenCenter	[in] center of rotation in screen coordinates

Implements CameraController.

setTransform()

void setTransform ( const rw::math::Transform3D<> &  t3d )

virtual

set world to camera transformation

Parameters

t3d	[in] world to camera transformation

Implements CameraController.
