[Paraview] Calculator and vector products

[Scott, W Alan]

Silly me, of course.  Math class was just too many years ago.

Hello

The + sighs between cross terms should be replaced by - signs as follows:
    i ( a_2b_3 - a_3b_2 )
 + j ( a_3b_1 - a_1b_3 )
 + k (a_1b_2 - a_2b_1 )

I don't know if this is correct, but I took a quick attempt at making a cross product.  I am using the dataset can.exo.  In the calculator, I am trying to create the cross of the DISP and ACCL vectors.  Here is the formula:

iHat*(DISPL_Y*VEL_Z+DISPL_Z*VEL_Y)+jHat*(DISPL_X*VEL_Z+DISPL_Z*VEL_X)+kHat*(DISPL_X*VEL_Y+DISPL_Y*VEL_X)

I am trying to do a vector product with the Calculator, but this seems to fail "Error deciding between ambiguous operators".
Is there a way to do vector products ? Or is this something that needs to be implemented ?
