Is there anyway to see the triangle count of a mesh? (answered)

ZBrush Usage Questions

I can’t seem to find this feature, if there even is one?

#2

No, but it’s easy enough to figure out.

ZBrush gives you the number of points. The number of points minus 2 gives you the number of quads and one quad equals 2 triangles.

So…

(number of points minus 2) x 2 = number of triangles

#3

Hover your curser over the tool in the Tool / SubTool palette to show infomation about your sub tool. This includes the number of polygons. If you know you only have quads, just double this number.

#4

Why double ? A polygon consists two triangles, so divide to two and you get the tris… Am i wrong ?

#5

Yes. :slight_smile: If a quad is divided into two tris then there are twice as many tris as quads.

zber2, Your math won’t always work. The points/polygons ratio depends on how many poles (points that belong to more than four polygons) there are.

Oh, im so stupid… :mad:

My appologies, you are right. I assumed that points were the same as vertices. Even so, they would all have to be quads. My bad…brain fart…:confused: :o at least I was half right :lol:

zber2,
Points are the same as vertices. And yes, for the quads x 2 = tris calculation to be accurate the mesh must be all quads. Of course it will be for every subdivision level above 1.
