◆ Point3() [2/2]

Member Function Documentation

◆ Ext()

template<class P3ScalarType >

P3ScalarType vcg::Point3< P3ScalarType >::Ext ( const int i ) const

inline

Padding function: give a default 0 value to all the elements that are not in the [0..2] range. Useful for managing in a consistent way object that could have point2 / point3 / point4

◆ FromPolarRad()

template<class P3ScalarType >

void vcg::Point3< P3ScalarType >::FromPolarRad	(	const P3ScalarType &	ro,
		const P3ScalarType &	theta,
		const P3ScalarType &	phi
	)

inline

Convert from polar coordinates to cartesian coordinates.

Theta is the azimuth angle and ranges between [0, 2PI) radians. Phi is the elevation angle (not the polar angle) and ranges between [-PI/2, PI/2] radians.

Note: Note that instead of the classical polar angle, which ranges between 0 and PI degrees, we opt for the elevation angle to obtain a more intuitive spherical coordinate system.

◆ operator=() [1/2]

template<class P3ScalarType >

Point3& vcg::Point3< P3ScalarType >::operator= ( Point3< P3ScalarType > const & p )

inlinedefault

Default copy assignment

◆ operator=() [2/2]

template<class P3ScalarType >

template<class Q >

Point3& vcg::Point3< P3ScalarType >::operator= ( Point3< Q > const & p )

inline

Copy assignment from Point with different template

◆ ToPolarRad()

template<class P3ScalarType >

void vcg::Point3< P3ScalarType >::ToPolarRad	(	P3ScalarType &	ro,
		P3ScalarType &	theta,
		P3ScalarType &	phi
	)		const

inline

Convert to polar coordinates from cartesian coordinates.

Theta is the azimuth angle and ranges between [0, 2PI) degrees. Phi is the elevation angle (not the polar angle) and ranges between [-PI/2, PI/2] degrees.

/note Note that instead of the classical polar angle, which ranges between 0 and PI degrees we opt for the elevation angle to obtain a more intuitive spherical coordinate system.
