Detailed Description

template<typename vector3_type>
class OpenTissue::scan_conversion::FragmentIterator< vector3_type >

Fragment Iterator. Typical usage is as follows:

typedef FragmentIterator<vector3_type> fragment_iterator;

vector3_type v1; vector3_type v2; vector3_type v3; vector3_type n1; vector3_type n2; vector3_type n3;

pragment_iterator pixel ( v1, n1 , v2 , n2, v3 , n4);

while( pixel() ) { std::cout << "sreen x = " << pixel.x() << "sreen y = " << pixel.y() << "normal = " << pixel.normal() << std::endl; ++pixel; }

Constructor & Destructor Documentation

template<typename vector3_type>

virtual OpenTissue::scan_conversion::FragmentIterator< vector3_type >::~FragmentIterator

(

)

[inline, virtual]

template<typename vector3_type>

OpenTissue::scan_conversion::FragmentIterator< vector3_type >::FragmentIterator	(	vector3_type const &	v1,
		vector3_type const &	n1,
		vector3_type const &	v2,
		vector3_type const &	n2,
		vector3_type const &	v3,
		vector3_type const &	n3
	)			[inline]

vertex coordinates are assumed to be transformed into screen space of the camera. Normals can be given in whatever coordinate frame one wants. Just remember that normals are lineary interpolated in screen space.

		vector3_type const &	v2,
		vector3_type const &	v3

vertex coordinates are assumed to be transformed into screen space of the camera.

Returns:

If there are any more fragments left then the return value is true otherwise it is false.
