My simple experiment of Prim Equivalent

[TANAKAAKIO Inshan]

Though it is too late.

I am trying to manage to reduce PEs of meshes of my car.
The mechanism is mysterious for me.

After I saw following results, I figured out the aspect vaguely.

PEs of meshes change significantly depending on the sizes.
This is more than I could have imagined.
I think that tiny avatars may have advantage in PE.

 

In Blender.

Of course this cylinder is single prim as a sculpted prim.

But as a mesh...

 

 

Next small and more simple.

 

Minumum of PE  is 2.0.

Wellcome to the wonderful world of Linden mathematics. You can read about it in the links here. Be prepared with headache remedies. By the way, you will probably find the cylinders have lower PE if you make their circumferences smooth.

The reason is because the smaller a mesh is the more triangles an avatar can bump into causing physics work. Also the smaller a mesh is than the more triangles would see if that mesh were copied to sim capacity and distributed evenly at ground level.

Thanks for your advice.　It is good for studying .
It's so complicated and have a profound effect.
I saw that PE generates controversial and hottest issue in this forum.

Headache? I feel a pain in my left shoulder a bit recently.
It seems that PEs irritate an old wound in my left shoulder instead.

when an object is =< 0.20 it automatically becomes a box for the physics hence the sudden drop in Phy wt.

As for the stand anone min PE cost is 1.5 rounded to 2.0

if a mesh PE is 0.5 for example a trianlge and is not linked it is 1.5 (2.0 ronded). BUT the more that are linked reduces the min cost linking 200 these would be close to 100 PE total (actual 101) averaging 0.5 PE per mesh. Unless the object scripted/physical then the min cost is 3.0 for stand alone and 1.0 min when max number linked. thus the linkset of 100 prims is close to 200 (actual 202) since min cost when scripted/physical is now 1.0.

Also as Drongle stated if you have no smoothing on your model cost may be over exagerated. Also the more UV stiched together also the better example as follows
