Detailed Description

class to represent a Sphere in 3d space. (float) keep the radius squared for faster access.

◆ cSphere2() [2/2]

Member Function Documentation

◆ get_RadiusSq()

inline

◆ GetRayIntersectionFrustum()

GINTERSECT_TYPE GrayLib::cSphere2::GetRayIntersectionFrustum ( const cVector3f &  vRayOrigin,
const cVector3f &  vRayDir,
cVector3f *  pvIntersect,
DVALUE_t  fDistMaxSq 
) const

ray to sphere intersection test

Note
ASSUME vDir is normalized!
Returns
0 = GINTERSECT_None = no intersect. 1 = GINTERSECT_Partial = intersect. 2 = GINTERSECT_In1 = intersect from inside.

◆ IsRayIntersectionDistSq()

bool GrayLib::cSphere2::IsRayIntersectionDistSq ( const cVector3f &  vRayOrigin,
const cVector3f &  vRayDir,
DVALUE_t  fDistMaxSq,
OUT cVector3f *  pvIntersect 
) const

Similar to D3DXSphereBoundProbe but with intersection returned.

◆ IsRayIntersectionInFront()

bool GrayLib::cSphere2::IsRayIntersectionInFront ( const cVector3f &  vRayOrigin,
const cVector3f &  vRayDir,
cVector3f *  pvIntersect 
) const

No idea what this means. what is the 'front' of a sphere ? closest intersection to vRayOrigin ?

◆ put_Radius()

void GrayLib::cSphere2::put_Radius ( DVALUE_t  fRadius)

◆ SetSphere()

void GrayLib::cSphere2::SetSphere ( const cVector3f &  vCenter,
DVALUE_t  fRadius 
)
inline
