Detailed Description

Add intersection functions.

<glm/gtx/intersect.hpp> need to be included to use these functionalities.

genType const &  point1,
genType const &  sphereCenter,
typename genType::value_type  sphereRadius,
genType &  intersectionPosition1,
genType &  intersectionNormal1,
genType &  intersectionPosition2 = genType(),
genType &  intersectionNormal2 = genType() 
)

From GLM_GTX_intersect extension

bool glm::intersectLineTriangle ( genType const &  orig,
genType const &  dir,
genType const &  vert0,
genType const &  vert1,
genType const &  vert2,
genType &  position 
)

Compute the intersection of a line and a triangle.

From GLM_GTX_intersect extension.

bool glm::intersectRayPlane ( genType const &  orig,
genType const &  dir,
genType const &  planeOrig,
genType const &  planeNormal,
typename genType::value_type &  intersectionDistance 
)

The ray direction vector is unit length. From GLM_GTX_intersect extension.

bool glm::intersectRaySphere ( genType const &  rayStarting,
genType const &  rayNormalizedDirection,
genType const &  sphereCenter,
const typename genType::value_type  sphereRadius,
genType &  intersectionPosition,
genType &  intersectionNormal 
)

From GLM_GTX_intersect extension.

bool glm::intersectRayTriangle ( genType const &  orig,
genType const &  dir,
genType const &  vert0,
genType const &  vert1,
genType const &  vert2,
genType &  baryPosition 
)
