Constructor & Destructor Documentation

CameraRay::CameraRay (  const Vector3  o, const Vector3  d, Scene *  s, InsideList *  l )

Constructs new camera ray. Parameters: o  ray's origin d  ray's direction s  scene belonging to ray l  list of object which is the ray inside at origin

CameraRay::CameraRay (  const CameraRay &  r  )  [inline]

Copy constructor.

Member Function Documentation

Colour CameraRay::evaluateMedia (  Colour &  absorb  )  const

Evaluate media interval. Calculates the colour contribution by the interval between ray's origin and hitpoint.

InsideList* CameraRay::getInside (   )  const [inline]

Get list of objects which the ray is inside in.

FLT CameraRay::getWeight (   )  [inline]

Returns ray's contribution factor to the resulting colour.

Vector3 CameraRay::hitpoint (   )  const [inline]

Returns the intersection point.

Vector3 CameraRay::normal (   )  const [inline]

Returns object's surface normal at intersection

void CameraRay::reflect (  FLT  weightmult  )

Reflect ray. Parameters: weightmult  factor for colour weight reduction

bool CameraRay::refract (  FLT  weightmult  )

Refract ray. Parameters: weightmult  factor for colour weight reduction Returns: true if total reflection has occured else false

void CameraRay::scaleWeight (  FLT  s  )  [inline]

Scale ray's contribution factor. Parameters: s  factor

bool CameraRay::shoot (   )

Shoot ray. Calculate the ray-scene intersection.

Texture* CameraRay::texture (   )  const [inline]

Returns object's texture at intersection
