Detailed Description

template<typename Scalar>
class ACG::Geometry::PlaneT< Scalar >

This class stores a plane in normal form and provides useful algorithms for left/right test, itersection, and so on.

Member Function Documentation

template<typename Scalar >
bool ACG::Geometry::PlaneT< Scalar >::intersect ( const Vec3 _v0,
const Vec3 _v1,
Vec3 _v,
Scalar &  _t,
IntersectionTarget  _target 
) const
inline

General intersection function.

General intersection between a line/ray and the plane.

Parameters
_v0start vector of the ray
_v1end vector of the ray
_vreturned intersection point
_treturned relative distance from the interection to _v0 compared to _v1
_targettype of intersection to test
Returns
true if an intersection was found
