[ccp4bb] Model Building: continuous update of distances as fragment moved

[Paul McLaughlin]

In doing some model building I want to move a domain of a protein 
manually, as a rigid body, and see in real time continuous updates of 
some distances from points on the domain to the rest of the protein (we 
have cross linking data).
I dimly remember being able to do with this O,at least a decade ago 
(probably more),  but it doesn't seem to work in current versions (I 
have even dimmer recollections that this might have been a special 
feature of a particular graphics card in an SGI)
In any event, does anyone know of anything that might allow us to do 
this? { I am not asking about computational ways of exploring alternate 
packing of the domain to satisfy distances ( I know about these) - 
rather we want to get a feel for what is possible by "seeing" it for 
ourselves).
