[Plugin] Drape Cpoints
-
Sounds pretty complicated !
Don't you want something inside SketchyPhysics like a 'chain of hinged links' that you anchor at its two ends and it then 'sags' appropriately ?
Each 'chain' would be made representing a 'rib' of a 'mesh' or 'net'...
You'd then swap the links for simple edges and explode stuff and you have the basis of the surface ???
My brain hurts already...
Thomthom is making a Vertex Editor and that might help ?
Remus has also done some work on Catenary Curves...
These things combined might do what you want BUT it'd be at the end of along list for me... others might pick up the gauntlet ?
-
Sounds like he's looking for a real physics based cloth simulation plugin for sketchup. That seems as though it would be better integrated into sketchy physics as it has the framework for gravity simulation. I would love to see it, but I imagine it's still a far way off unless SU 8 implements a better engine under the hood.
-
great plugin. thankyou. here is the .zip file that contains this and the other two plugins needed to create a mesh. maybe you could add it to your original post. would be less confusing for some.
-
TIG..I've got a problem.
The construction points appear, but they are not draped over the mesh (see screengrab). It just creates a regular, flat grid of c points under my mesh.
Am I doing something wrong?
-
Never mind, I've got it to work now. You have to drape points over a group....I was triple clicking the mesh and then trying to use the plugin. duh!
I am using this to simplify a dirty 3D topographical survey and it work beautifully! such a good idea. I was just about to start manually draping construction points then I thought, "hang on a minute.....there MUST be a plugin for this"
so thank you ever so much for taking the time to make and share this wonderful ruby! It will save me lots and lots of time and stress so hats off to TIG! bravo!

If I remember correctly, the Archiland plugin has a tool that recreates a terrain in a regular pattern: http://forums.sketchucation.com/viewtopic.php?f=323&t=13760#p102771

ah thomthom thank you!! i didnt know that plugin existed. you can really simplify a mesh with it, nice one!! and cheers to cadfather too.
here is a screenshot of my mesh tests.
Think i will be using the triangulated construction points at 5000mm centres....detailed enough for my needs. I love the archiland "simplify contours" tool as well, its a great idea.

Another use for the script.....5 minute bedspread. (Bed model from warehouse)
adam,
did you just move the points using the regular move tool or did you use another plugin to make the bedspread?
-
Yes, Edson I just moved the Cpoints manually before running the triangulate plugin to give the appearance of ruffled edges. I also used JPP to give thickness to simulate the fold over atop the pillows.

The script 'points_cloud_triangulation.rb' [which shows in the Plugins menu as 'Triangulate Points'] is here...

that also requires 'delauney2.rb' - which you can get here...

I have recently updated a version of the 'cloud' tool and a related delauney3 - do a search on the Plugins forum...

Hi,
Note that I recently changed the old typo in the main script 'require ./delauney2.rb' to 'require 'delaunay2.rb'
The required file has been renamed 'delaunay2.rb'

hi,
could you please make step by step tut for creating your wonderful "5-minute bedspread" for those, who´re in the process of learning, just a bit far behind you (youtube is fine too)thanks !
-
Excellent Adam
-
Nice tut!
-
Wow Adam that is a cool tutorial.
-
Thanks guys..glad it was helpful. Here's a few tests of the method on different shapes. It's not as good as a physics based cloth simulation, but the results are fairly convincing. For table cloths, you just need to make sure you have a ground shape object that is slightly larger than the table and in the same group, so that the Cpoints will drape down and onto the ground. The same method can be used to make water in a stream bed or snow on a rooftop.
-
hi earthmover,
thanks for your valuable time and desire to share your knowledge among sketchup fans/learners.
it´s pretty cool, well done!
cheers! -
Tibet, here is a quick tutorial on the bedsheet.

"and a related delauney3" can't find this?
