[Closed] get coordinates of each vertex on plane

Hi.

This function will return an array with the world-space vertex positions for the object “obj”.

fn getVertexPositions obj = (
	local vPositions = #()
	local triMesh = snapshotAsMesh obj
	for v = 1 to triMesh.numVerts do (
		append vPositions (getVert triMesh v)
	)
	delete triMesh
	return vPositions
)

Did you mean that?

Looks like it, but I am not able to run this; it gives a runtime error “snapshotAsMesh requires a node”.
Thanks for the quick reply

Try getVertexPositions $

Light

If I try
getVertexPositions $Plane01
it Works!
(Plane01 is the name of the object in my scene.)

But
when I try
getVertexPositions ($+objName)
OR
$objname
Doesn’t Work!
(obName is the name of object in my script)

Any help on this.

if you mean you assigned a variable objname to the object in your scene like this:

objname = $Plane01

then you call the function with just the variable name as the argument like this:

getVertexPositions objname

Thats what I tried for the first time
Did not work

I have one object in my scene named “Plane01” and this works fine for me:

fn getVertexPositions obj = (
	local vPositions = #()
	local triMesh = snapshotAsMesh obj
	for v = 1 to triMesh.numVerts do (
		append vPositions (getVert triMesh v)
	)
	delete triMesh
	return vPositions
)

objname = $Plane01
getVertexPositions objname

What are you doing differently?

Say I have a list of object names in an array; Plane01, Plane02 etc
This way I do not have “$” in front. I tried adding that to the name and it still gives problems.

fn getVertexPositions obj = (
::::::::::::
::::::::::::
)

newName = “$”+objName
getVertexPositions newName

Thank you for your reply
