Creates a plan.
plan = NEW_PLAN(
node1, node2, node3
) ;
plan
The plan.
node1
The first node defining the plan.
node2
The second node defining the plan.
node3
The third node defining the plan.
plan = NEW_PLAN( node, vector ) ;
plan
The plan.
node
A node contained by the plan.
vector
The vector normal to the plan.
plan = NEW_PLAN( A, B, C, D ) ;
plan
The plan defined by the formula.
A
The A coefficient.
B
The B coefficient.
C
The C coefficient.
D
