void CCameraPathInterpolator::compute

(

)

[protected]

Computes path.

CCameraKeyPathPoint* CCameraPathInterpolator::getFrame

(

int

nFrame

)

[inline]

Returns frame of computed path. frame in [1..getNumFrames()]

int CCameraPathInterpolator::getNumFrames

(

)

[inline]

Returns total number of frames of computed path.

CList<CCameraKeyPathPoint> CCameraPathInterpolator::getPath

(

)

[inline]

Returns computed path.

CCamera CCameraPathInterpolator::mul	(	const CCamera &	c,
		const double	d
	)			const [inline, protected]

Multiplies CCamera with double value Copies CCamera, multiplies (eye, ref point, view up, ratio, fovy, vpheight)

CCamera CCameraPathInterpolator::sub	(	const CCamera &	c1,
		const CCamera &	c2
	)			const [inline, protected]

Subtracts two CCameras. Copies first CCamera, subtracts (eye, ref point, view up, ratio, fovy, vpheight)
