◆ doInversePerspective()

template<class T>

virtual bool OdGiWrapperViewport< T >::doInversePerspective ( OdGePoint3d & p ) const

inlinevirtual

Applies the inverse of the current perspective transformation to the specified point.

Parameters

point [in/out] Point relative to which the inverse transformation is applied. Receives point coordinates after transformation if successful.

Remarks: The point is transformed from normalized device coordinates to EyeSpace coordinates

true if the point was transformed; i.e., an inverse perspective transform is active, and the point was neither too close or behind the camera.

◆ getFrontAndBackClipValues()

template<class T>

virtual bool OdGiWrapperViewport< T >::getFrontAndBackClipValues	(	bool &	clip_front,
		bool &	clip_back,
		double &	front,
		double &	back ) const

inlinevirtual

Returns the front and back clipping parameters for the associated Viewport object.

Parameters

clipFront	[out] Receives true if and only if front clipping is enabled.
clipBack	[out] Receives true if and only if back clipping is enabled.
front	[out] Receives the front clipping distance.
back	[out] Receives the back clipping distance.

Returns: true if clipFront || clipBack which means that one of the values is non-zero, false otherwise.

Remarks: front and back are the eye coordinate Z values.

Clipping planes are perpendicular to the view direction.

If the front clipping plane is enabled, geometry in front of it is not displayed.

If the back clipping plane is enabled, geometry in back of it is not displayed.
