詳解

MGglViewAttrib is a class to serialize MGOpenGLView.

MGglViewAttrib is used by MGOpenGLView and MGContext to define view-mode, construction plane's geometry data, and viewing transformation matrix data.

関数詳解

const MGPosition& MGglViewAttrib::center ( ) const

inline

return the center of the box of this view.

MGPosition& MGglViewAttrib::center ( )

inline

void MGglViewAttrib::compute_viewing_environment

(

const MGBox &

box

)

Compute the viewing environment the parameter box. compute_viewing_environment() uses (eye_position,view_up_vector) as input. They must be set before compute_viewing_environment.

引数

box	Input the box of the target scene.

void MGglViewAttrib::copy

(

const MGOpenGLView &

glview

)

~MGglViewAttrib();

Copy the informations of glview2 into this.

const MGConstructionPlane& MGglViewAttrib::cplane ( ) const

inline

MGConstructionPlane& MGglViewAttrib::cplane ( )

inline

double MGglViewAttrib::diameter ( ) const

inline

Obtainthe the diameter of the sphere that surround the whole model.

double& MGglViewAttrib::diameter ( )

inline

const MGPosition& MGglViewAttrib::eye_position ( ) const

inline

Get the eye position.

MGPosition& MGglViewAttrib::eye_position ( )

inline

bool MGglViewAttrib::is_perspective ( ) const

inline

Return if this is a perspective view or not.

void MGglViewAttrib::set_center ( const MGPosition &  pos )

inline

void MGglViewAttrib::set_fovy ( double  fovy )

inline

void MGglViewAttrib::set_perspective	(	bool	pers,
		double	fovy = 45.
	)

Set if this view is a perspective view(true), or orthnormal view(falsle).

void MGglViewAttrib::set_view_up_vector ( const MGVector &  up )

inline

Set the view-up vector.

void MGglViewAttrib::setEyePositionUpVector	(	const MGPosition &	eyeP,
		const MGVector &	upVector
	)

Set m_eyeP and m_up_vector(the eye position and view-up-vector of the OpenGL).

void MGglViewAttrib::setHomeMatrix

(
