Detailed Description

a 3d cylinder of unit radius 1. Used for sphere sweep collision detection with triangles. cSegment3f = center ray starting at point (m_vMin) and proceeding to m_vMax in 3d space.

Constructor & Destructor Documentation

◆ cCylinder() [1/2]

GrayLib::cCylinder::cCylinder ( )
inline

ASSUME m_vMin,m_vMax are undefined.

◆ cCylinder() [2/2]

GrayLib::cCylinder::cCylinder ( const cVector3f &  v1,
const cVector3f &  v2 
)
inline

Member Function Documentation

◆ GetIntersectWithTri()

bool GrayLib::cCylinder::GetIntersectWithTri ( const cTriangle3f &  Tri,
OUT cVector3f &  rvCollisionPoint,
OUT DVALUE_t &  rfDistToCollision 
) const

Does the cylinder of unit radius 1 collide with the triangle?

Returns
fDistToCollision = distance along cCylinder (from m_vMin) to vCollisionPoint

◆ GetLowestRoot()

bool GrayLib::cCylinder::GetLowestRoot ( DVALUE_t  a,
DVALUE_t  b,
DVALUE_t  c,
DVALUE_t  maxR,
OUT DVALUE_t &  rfRoot 
)
static

check if solution exists. Called by GetIntersectWithTri()

◆ UNITTEST_FRIEND()

GrayLib::cCylinder::UNITTEST_FRIEND ( cCylinder  )

◆ Update()

void GrayLib::cCylinder::Update ( )
inline

if cSegment3f changes call this.

Member Data Documentation

◆ m_vDir

cVector3f GrayLib::cCylinder::m_vDir

derived values from cSegment3f

vector of move. m_vMax - m_vMin

◆ m_vDirNorm

cVector3f GrayLib::cCylinder::m_vDirNorm

normalized vector of m_vDir.
