[ODE] tricollider question

[Henry]

It's perfectly acceptable to cast a dVector into a dcVector but it looks 
like it was done with references so that all the dcVector operators and 
functions could be used on the dVector in place. I could make a copy and 
then write it back but I suppose the real question is why not just do 
the operations on the original data ie write the missing functions for 
dVector ( operator *, DotProduct etc) Can anyone think of a good reason 
why this couldn't be done?
