Q MAXSCRIPT : Local vertex rotation data

leslievdb

i would like to know how i can retrieve the local rotation parameters from a vertex in maxscript.

MoP

If by "rotation" you mean "average normal" then this should be fairly easy to determine.

A vertex on its own has no inherent "rotation" as such...

Is there a difference in average normal and normal or is it the same ?

does that normal correspondent with the direction the z axis is pointing at in the example (i am looking for that direction)?

i currently calculate my normals by using this method, but it doesn`t seem to be doing the trick

fn GetVertNormal obj vert =
(
vertFaces = polyOp.getFacesUsingVert obj vert
tNormal = [0,0,0]; for i in vertFaces do tNormal += polyOp.getFaceNormal obj i
tNormal / vertFaces.numberSet
print tNormal
return (tNormal)
)

PolyHertz

The 'normal' of a vertex is simply the averaged normals of the surrounding faces. Get the verts connected faces, then use the polyop.getFaceNormal function for each and average to get the normal.

Maybe something like this:

vrtNum = (polyOp.getVertSelection $.baseObject) as array
vrtFacs = (polyop.getFacesUsingVert $ vrtNum) as array
vNormal = [0,0,0]
for vf in vrtFacs do (vNormal = (polyop.getFaceNormal $.baseObject vf) + vNormal)
tNormal = vNormal / vrtFacs.count


It could also help to know what your trying to do with this.

tnx polyhertz , seems to me that the problem is somewhere else in the code but i think i`ll be able to find it ^^

i`m working on a wrapmode (lowpoly wrapping around highpoly) for a tool that i am making btw )
