Increase detail level of 3D polygon Face

[Jack2022]

Hi All,

 

hopefully an easy one. 

 

Is there a way to simply divide a 3D polygon face into more faces then lift up the new vertices while the outside edges remain glued in place (I.e I dont want to create gaps in the overall mesh structure). Increasing the polygon detail of this rock for eg.

 

 

Many thanks,

 

Jack

Is it just one polygon or many that you want to convert?

[Jack2022]

one would be good as the rocks are generally good shapes but there are a few glaring flat sides I want to make not flat

 

[Jack2022]

to be honest which ever way reduces the larger flat faces so if it applies to the whole object then thats ok but I wondered if the control of one face at a time allows me some conrtrol

I don't see a function in Vectorworks that does sub-divide automatically, but maybe someone else knows if there is

 

You may have to convert your object to individual 3D polygons (Convert to 3D polygons)  and work on them that way.  Once you fix the offending geometry, then use add solids to reconnect them.

 

If you can share the geometry, it might be easier to explain.

Any way to make this flat face look more rock-like would be helpful. simplest way best. All the faces are 3D polygons. Not connected. I can move them about but they detach from one another which I dont want. I can convert to nurbs and add vertices which moving about but again you get the face splitting off form the others

Did this very quickly, trying to dial in.  Something like this.  Can make much rougher.

I do not know — but I would think that Marionette would be able to do something like this.

 

I found this thread below which has a Marionette network to randomly triangulate objects, I would think it could be modified to randomly move the points — but I have no idea how.
 

Maybe @Marissa Farrell could enlighten us whether this would be possible.

Thankyou both. 

 

To Virtual - was looking to increase the triangulation of the face. I did have a go with this sort of nurbs manipulation but was after larger simpler facets. When I pulled up the nurbs face it pulled away from the abutting polygons. 

 

rDesign - this looks ideal. Was hoping there would be a simple tool to divide up the face though. This option requires scripts which on a google looks like a bit of a slog to install and get working. 

 

If theres no obvious tool i'm missing I'll just supplement the symbol with some extra rocks to make it look more natural. 

 

Thanks again for your time though.

Got it - Taper Face with Picked Face Mode does a decent job

What about converting the 3D Poly into a Subdivision then Edit Subdivision Tool...? Split Mode then Transform Mode.

[Jack2022]

this look promising Tom. It insisted on making a hemisphere though and deleted the source face: 

 

 

have I got a setting set to create a dome or something? 

[Jack2022]

Im looking it up - thanks for help all.

[Tom W.]

I just tried it on a triangular-shaped 3D Poly + it seemed to work but I don't know much about Subdivision so could be aspects I'm missing...

[VIRTUALENVIRONS]

Sorry, in and out today.  This works fairly simple and  quickly.  Use the Cut tool to slice the polygon face the way you want it and convert to mesh.  Then move the points upward.

@Jack2022  I could not get any time yesterday, but there is a functional way to do this.  Below is a short video explaining the process.  Very easy and controllable.

This is great thank you! and appreciate the video and time. I shall use this method!

Yes, you just need to change settings in the subdivision tool. I would go with the subdivision method, much easier & faster to adjust than anything that involves converting between object types.

Note that if you want to keep the object as a collection of flat faces, make sure that all the faces you add are triangular. As you can see at the end of the recording, if you adjust the vertice of a face with more than 3 vertices it will make it into a curved surface.
