template<typename coord_t>
struct teca_geometry::polygon< coord_t >

@breif The vertices of a 2D polygon in clockwise order. The first and last point are required to be the same.

Member Function Documentation

copy()

template<typename coord_t >

template<typename in_coord_t >

void teca_geometry::polygon< coord_t >::copy	(	const in_coord_t *	in_vx,
		const in_coord_t *	in_vy,
		unsigned long	in_n_verts
	)

deep copy the vertices of the polygon.

from_stream()

template<typename coord_t >

int teca_geometry::polygon< coord_t >::from_stream

(

teca_binary_stream &

bs

)

deseriealize from the given stream

get_bounds()

template<typename coord_t >

void teca_geometry::polygon< coord_t >::get_bounds

(

coord_t *

bounds

)

compute an axis aligned bounding box around the polygon with the layout [x0 x1 y0 y1].

inside()

template<typename coord_t >

bool teca_geometry::polygon< coord_t >::inside	(	coord_t	px,
		coord_t	py
	)

returns true if a point is inside the polygon

normalize_coordinates()

template<typename coord_t >

void teca_geometry::polygon< coord_t >::normalize_coordinates

transforms coordinates to be in [0 360 -90 90]

to_stream()

template<typename coord_t >

void teca_geometry::polygon< coord_t >::to_stream

(

teca_binary_stream &

bs

)

serialize to the given stream
