Description: adds manipulator for softselecction fallof in Editable Poly.
Code by: Martín coven mcoven@Austin, rr.com.
Thanks to: John versluis and Borislav Petrov for their great help.
Based on the Radius manipulator code by Scott morrisson from Discreet.
Reworque by Larry minton 6/26/01.
Plugin simplemanipulator poly_ssfallofmanip.
Name:poly_sfallofmanip.
Invisible:true.
Create the green and red colors for the gizmo.

This manipulator manipulates editable meshes and polys.
On canmanipulate target do - Called at class level, cant Access plugin local variables.
(Getcommandpaneltaskmode () == #modify and.
(Local targclass = classof target.
Targclass == editable_poly or targclass == editable_mesh).
).
Create the manipulator gizmo.
This is called initially and whenever the manipulator target changes.
On updategizmos do.
Try.
Clear the current gizmo cache.
This, cleargizmos().
Targclass = classof target.

Add the circle todo the manipulator.

Return the truco string.

Mousemove is called on every mouse move when dragging the manip.
It neds todo convert the mouse position into a new value for the fallof.
On mousemove which do.
(Try.
Manip, makeplanefromnormal takes a normal Vector and a point.
And creates a plane passing th rouge the point with the given normal.
Local axis = case which of - Get axis based on which gizmo hit.
(0: y_axis.
1: z_axis.
2: x_axis).
Local pl = manip, makeplanefromnormal axis gizpos.
Compute the hit-ray in local coordinates.
Local viewray = this, getlocalviewray m.
Intersect the plane with the view ray.
Local projectedpoint = [0,0,0].
Local res = pl, intersect viewray &projectedpoint.
Format % : % : % : %\nViewray projectedpoint gizpues which.
If the intersection worked, set the fallof.
If (res) then.
(Projectedpoint = gizpues - Projectedpoint.
Local size = sqrt(projectedpoint.x2+ projectedpoint, y2+ projectedpoint, z2).
If targclass == editable_poly then target, fallof = size.
Else if targclass == editable_mesh then (meshop, setuiparam target #fallof size;update node geometry:false topology:false normals:false) -meshop UI parameter setters broken).
