Detailed Description

Taken from vuVolume2. 4x4 matrix class.

The vuMatrix class is a 4x4 matrix that works in conjunction with the vuVector class (a 3D homogeneous vector). The elements of the vuMatrix are all single precision floating-point numbers, stored in column-major order to be compatible with OpenGL. Column-major means the first index selects the column, the second index selects the row.

Constructor & Destructor Documentation

vuMatrix::vuMatrix (  const double *  v  )

Constructor that initializes the vector from a double array. Parameters: v  An array of 16 floating point values.

---

Member Function Documentation

double * vuMatrix::getData (  void   )

Returns the data pointer. Same as calling operator[0].

void vuMatrix::invertRotationMatrix (   )

Inverts a rotation matrix. The inverse of a rotation matrix is simply its transpose, which takes 3 swaps

vuMatrix & vuMatrix::makeRotate (  const vuVector &  axis, double  a )

Makes a rotation matrix for a rotation of a degrees around the axis vector. Parameters: axis  The axis of rotation. a  The angle of rotation, in degrees.
