Detailed Description

template<typename T>
class Triangle< T >

DGL Triangle class.

This class describes a triangle, defined by 3 points.

Constructor & Destructor Documentation

Triangle() [1/4]

template<typename T >

Triangle< T >::Triangle ( )

noexcept

Constructor for a null triangle.

Triangle() [2/4]

template<typename T >

Triangle< T >::Triangle ( const T &  x1, const T &  y1, const T &  x2, const T &  y2, const T &  x3, const T &  y3  )

noexcept

Constructor using custom X and Y values.

Triangle() [3/4]

template<typename T >

Triangle< T >::Triangle ( const Point< T > &  pos1, const Point< T > &  pos2, const Point< T > &  pos3  )

noexcept

Constructor using custom position values.

Triangle() [4/4]

template<typename T >

Triangle< T >::Triangle ( const Triangle< T > &  tri )

noexcept

Constructor using another Triangle class values.

Member Function Documentation

isNull()

template<typename T >

bool Triangle< T >::isNull ( ) const

noexcept

Return true if triangle is null (all its points are equal). An null triangle is also invalid.

isNotNull()

template<typename T >

bool Triangle< T >::isNotNull ( ) const

noexcept

Return true if triangle is not null (one its points is different from the others). A non-null triangle is still invalid if two of its points are equal.

isValid()

template<typename T >

bool Triangle< T >::isValid ( ) const

noexcept

Return true if triangle is valid (all its points are different).

isInvalid()

template<typename T >

bool Triangle< T >::isInvalid ( ) const

noexcept

Return true if triangle is invalid (one or two of its points are equal). An invalid triangle might not be null under some circumstances.

draw() [1/2]

template<typename T >

void Triangle< T >::draw

(

const GraphicsContext &

context

)

Draw this triangle using the provided graphics context.

drawOutline() [1/2]

template<typename T >

void Triangle< T >::drawOutline	(	const GraphicsContext &	context,
		T	lineWidth = 1
	)

Draw lines (outline of this triangle) using the provided graphics context, optionally specifying line width.

draw() [2/2]

template<typename T >

void Triangle< T >::draw

(

)

Draw this triangle using the current OpenGL state.
DEPRECATED Please use draw(const GraphicsContext&) instead.

drawOutline() [2/2]

template<typename T >

void Triangle< T >::drawOutline

(

)

Draw lines (outline of this triangle) using the current OpenGL state.
DEPRECATED Please use drawOutline(const GraphicsContext&,T) instead.
