[IGSTK-Developers] View refactoring- Camera control

[Andinet Enquobahrie]

Team,

One of the main weaknesses of the view classes is lack of camera control as
pointed out by several people. As part of the view class refactoring 
effort,
I will be adding Request methods that provide control of  some of the 
camera
parameters to the user.

I am proposing to add the following methods

// Set camera position
RequestSetPosition(double x., double y, double z);

//Set focal point coordinates
RequestSetFocalPoint( double x, double y, double z);

//Set view vector up
RequestSetViewUp( double vx, double vy, double vz);

//Set clipping range
RequestSetClippingRange( double dNear, double dFar);

//Set parallel projection on
RequestSetParallelProjectionOn( );

//Set perspective projection on
RequestSetPerspectiveProjectionOn()

Let me know if you see the need to have control of
other parameters of the camera.

Thanks
