示例1: getCameraTransformationMatrix
/** Get a reversed transformation matrix to be used for cameras
* @param matrix place to place matrix in
*/
void Position::getCameraTransformationMatrix(Matrix44f& matrix)
{
// z is reversed
Vector3f z(-forward.getX(), -forward.getY(), -forward.getZ());
// get x vector
Vector3f x;
x.crossProduct(up, z);
// matrix is transposed (rows instead of columns)
