Member Function Documentation

Vertex3 Matrix3::applyInverse (  const Vertex3 &    v )  const

. Note: Only for pure rotational matrices.

void Matrix3::construct (  Vertex3 &    up, const Vertex3 &    dir )

. Construct the orientation matrix given an up vector and direction. Parameters: up  up-vector or camera y-axis. dir  direction-vector or camera z-axis. Precondition: up and dir are normalized vectors. up and dir may not lie on the same line. Postcondition: The matrix orientation is aligned to the input vectors. up is recalculated and is orthogonal to dir.

void Matrix3::rotateX (  real    alpha )

Post concatanate x-axis rotation. Calculates:

void Matrix3::rotateY (  real    alpha )

Post concatanate y-axis rotation. Calculates:

void Matrix3::rotateZ (  real    alpha )

Post concatanate z-axis rotation. Calculates:
