Polygon Count
-
I tried my first serious SketchUp model on this new computer, and I very quickly ran into lag. I was encouraged to find my graphic card type and install all the latest drivers (which I did) but the help it offered was marginal. So now I'm wondering if the model I was doing simply had too many polygons, but I realize I don't even know how SketchUp counts it's polygons.
I did find this thing which counts "entities": http://i215.photobucket.com/albums/cc42/Edward_Wolf/Entities.png
And as my model increases in complexity the number of entities does increase. The cube has 6 sides though... and 18 entities... does this mean the entities include all surfaces and all edges? Anyway, my super Torus started making my computer cough blood at around 16000 entities, is that really that many? I have a dual core processor running at 2.8 GHz, 3 GB DDR3 RAM, and an Nvidia GeForce 9200 graphics unit. You'd think it would be able to handle a decent amount. What is the typical limits for polygons (or entities) for your average user?EDIT:
This is the super Torus that gave me so much grief, I didn't even get to finish it!

In Sketchup, polygons are faces, check model statistics for that count.

Window, Model Info, Statistics,
Got it, thanks. I'd still like to know what the average user's polygon count is though. If you all don't mind my asking.

Mind you, most other applications refers to polygons as triangles. Each SketchUp face is internally built up of triangles and one face can have a different number of triangles than the other.
So a face count is not the most accurate way to measure a model complexity.
You can use this plugin to get the number of triangles in a modelØ http://forums.sketchucation.com/viewtopic.php?f=323&t=33233&p=293079#p293079 -
Thomas, Thanks, I didn't know that. How do you count the triangles in a face?

face.mesh.count_polygons -
Note that at that moment of counting these triangles are just the 'potential triangles' in the face.
Other mesh tools can actually 'split up' the face into triangles if desired - the tools are used in exporters etc -
True, the count you get from
face.mesh.count_polygonsis SU's own internal triangulation. It might not match if you try to export and compare in another 3d application.But it works as a good complexity comparison between SketchUp models.
