View Full Version : Rounding all Vertices of a Mesh by nearest number?

04-30-2008, 06:34 PM
Hi guys,

Is there a way to round all vertices of a mesh to the nearest numbers? E.g. If a vertex is at 3.24 then round it down to 3 for example.

fn roundfloat floatvar =
if floatvar-(floatvar as integer) >= 0.5 then (return ceil floatvar as integer) else (return floor floatvar as integer)
for i = 1 to $.numverts do
positionvar = (polyop.getvert $ i)
positionvar.x = roundfloat positionvar.x
positionvar.y = roundfloat positionvar.y
positionvar.z = roundfloat positionvar.z
polyop.setvert $ i positionvar

Out of curiosity... why do you want to do this? Or am I not understanding the question correctly? :D

As expected... Bobo has a more elegant solution I just found in the Scrolls of the Ages(tm) aka the archives.

fn RoundFloat valfloat =
floor (valfloat + 0.5) as integer

It's just something for work. Having geometry without floats... Thank you very much it works! :)

Keep in mind that this is a biased rounding method. It's faster than a proper round (e.g. round-to-even), though.

You might want to check out this script also:

I've found it very useful for straightening up verts in a mesh and for fixing small offset errors in object positions.
