Detailed Description

A CkInterestViewable is a viewable whose reprojection (view coherence) is characterized by a set of "interest points".

The interest points are used to determine which view to use, and when views are out-of-date.

Member Function Documentation

void CkInterestViewable::setUnivPoints

(

const CkInterestSet &

univPoints_

)

[protected]

Subclasses MUST call this from their constructors or pup routines.

void CkInterestViewable::setCenter

(

const CkVector3d &

center_

)

[inline, protected]

Definition at line 399 of file ckviewable.h.

References center.

virtual bool CkInterestViewable::shouldRender	(	const CkViewpoint &	univ2screen,
		const CkView &	oldView
	)			[virtual]

Default implementation checks the rms reprojection error.

Implements CkViewable.

virtual CkView* CkInterestViewable::renderView

(

const CkViewpoint &

univ2screen

)

[virtual]

Uses newViewpoint and renderImage to build a new CkInterestView.

Implements CkViewable.

virtual bool CkInterestViewable::newViewpoint	(	const CkViewpoint &	univ2screen,
		CkViewpoint &	univ2texture
	)			[virtual]

Create a new texture viewpoint (univ2texture) for this new universe viewpoint (univ2screen).

Default implementation just windows the universe viewpoint to fit the new texture. Returns false if no viewpoint is possible or appropriate.

virtual void CkInterestViewable::renderImage	(	const CkViewpoint &	vp,
		CkImage &	dest
	)			[pure virtual]

Subclass-overridden routine: Render yourself into this new, *garbage-filled* ARGB image.

To change the image format, call dest.setLayout.

virtual double CkInterestViewable::getSize

(

const CkViewpoint &

univ2screen

)

[virtual]

Returns size of bounding sphere.

Reimplemented from CkViewable.
