Many ways to Flow a Mesh – Some post-class review notes:

The Flow/FlowAlongSrf Family

imported OBJ mesh from Blender

See below screenshot, refer to notes (click image to see bigger version):

"Flow" and "FlowAlongSrf"

  • A: The basic OBJ mesh modelled in Blender (Import)
  • B:  Draw guide curves using the line tool.
  • C:  Draw a Base surface (“Plane“).
  • D:  Blender mesh “A” is “Flow” along curve “D” (“Circle”) to produce “D1”
  • E:  Blender mesh “A” is “Flow” along curve “E” (“Circle”, “Split – Point”) to produce “E1”
  • F:  Blender mesh “A” is “Flow” along curve “F” (“Spiral”) to produce “F1”
  • G:  Blender mesh “A” is “Flow” along curve “G” (“Helix”) to produce “E1”
  • H1: Simple surface (“Plane“) is “Flow” along curve “H2” (“Helix“) to produce “H3”.  Then mesh “A” is “FlowAlongSrf” to produce “H4”
  • J1:  Simple Surface (“Plane“, “Rebuild“,  “PointsOn” to create the shape)is “Flow” along curve “J2” (“Helix“) to produce “J3”.  Then mesh “A” is “FlowAlongSrf” to produce “J4”
  • J3 is “Flow” along curve K1 (“Circle”)to produce “K2”.  Then mesh “A” is “FlowAlongSrf” to produce “K3”

You can see it kind of starts getting messy the more you start meddling with it.  Results will of course depend on what kind of geometry you have to start with.

Here are some renders of the different shapes:

The starting mesh, modelled in Blender

objects D1, E1 and F1, made using the "Flow" command

Objects G1, H4, J4, made using "Flow" and/or "FlowAlongSrf"

Objects K3, and another version of K3 which I can't remember how I got...

I have no idea what I did to get the other K3, some fluke combination of Flow/FlowAlongSrf.  Turned into quite a nice object.  It was a bit jaggy after the Flow operation in Rhino, so I imported it back into Blender and smoothed it out again.  Below is the result.  I think I might go get it printed….

Fluke-y version of K3 that turned out quite nice

Ahhh all those red ticks to fix...!
