Select Face Array

Submitted by kimarotta on Tue, 2012-06-05 06:57

Hi,

I need a help in faces...
I'm trying to collect some faces, some faces have an array but I can not load the array in setSelection ...

Thanks in advanced

	prov = $.selectedFaces as integer
-- Unable to convert: #faces(181, 234, 347 : $Editable_Poly:Plane003 @ [32.705963,272.583252,0.000000]) to type: Integer
 
prov
#faces(181, 234, 347 : $Editable_Poly:Plane003 @ [32.705963,272.583252,0.000000])
 
$.EditablePoly.SetSelection #Face #{prov}
-- Unable to convert: #faces(181, 234, 347 : $Editable_Poly:Plane003 @ [32.705963,272.583252,0.000000]) to type: Integer

Here we go


with redraw off
(
	max create mode
	plane1 = $Plane001
	plane1Mod = plane1.modifiers[#Vol__Select]
	modNode = plane1Mod.node
	plane2 = snapshot $Plane001
	prov1 = #{} -- empty bitarray
	intersectFrames = #()
	getFaceSel = getFaceSelection
	setfmID = setFaceMatID
	for t in 0 to 50 do
	(
		at time t 
		if (intersects plane1 modNode) do append intersectFrames t	
		local selFaces = getFaceSel plane1.mesh
		if selFaces.numberset != 0 do prov1 += selFaces
 
	)
	for f in prov1 do (setfmID plane2 f 2)
	plane2 = (convertto plane2 Editable_Poly)	
	plane1.baseobject = plane2
	delete plane2
	format "frames at intersection = %\n" intersectFrames
)

Little trick

This works with your file. Solution for Editable Poly object

with redraw off
(
	max create mode
	plane1 = $Plane001
	plane2 = snapshot $Plane001
	prov1 = #{} -- empty bitarray
	getFaceSel = getFaceSelection
	setfmID = setFaceMatID
	for t in 0 to 50 do
	(
		at time t 
		local selFaces = getFaceSel plane1.mesh
		if selFaces.numberset != 0 do prov1 += selFaces
	)
	for f in prov1 do (setfmID plane2 f 2)
	plane2 = (convertto plane2 Editable_Poly)	
	plane1.baseobject = plane2
	delete plane2
)

yes, I will use this

yes, I will use this separation to paint a map of footprint ... I do have one more question ... could somehow know which frame each collision that occurs?

this works only if you use

this works only if you use editable_mesh object not editable_poly.
open the file in attachments and run this code

plane1 = $Plane001
plane2 = $Plane002
prov1 = #{} -- empty bitarray
getFaceSel = getFaceSelection
setfmID = setFaceMatID
for f in 0 to 50 do
(
--sliderTime = f
	at time f 
	local selFaces = getFaceSel plane1.mesh
	if selFaces.numberset != 0 do prov1 += selFaces
)
--uncomment *line 14* i if you want to select faces
--plane2.selectedfaces = prov1 --
for f in prov1 do setfmID plane2 f 2 
update $

So, two question. when I use

So, two question.

when I use "prov = $. selectedFaces the BitArray" and then ask prov.count it returns the total number of faces and not the number of items in the array ...

.
above the editablepoly I have a Vol. Select modifier and when I use "prov = $.selectedFaces as bitarray" he can not get the selected faces anyone have any idea ?
