Constructor & Destructor Documentation

 csDVector3::csDVector3 ( )` [inline]`
 Make a new vector. The vector is not initialized. This makes the code slightly faster as csDVector3 objects are used a lot.

 csDVector3::csDVector3 ( double m )` [inline]`
 Make a new initialized vector. Creates a new vector and initializes it to m*<1,1,1>. To create a vector initialized to the zero vector, use csDVector3(0)

Member Function Documentation

 csDVector3 csDVector3::Unit ( ) const` [inline]`
 Returns the unit vector in the direction of this vector. Attempting to normalize a zero-vector will result in a divide by zero error. This is as it should be... fix the calling code.
