MODEL THIS: Loopita Bonita Lounger
-
None yet. Want to see if I can do with vanilla tools. I'd imagine Chris' stringer would make it easy. Maybe even shapebender.
-
Great start!
-
I wish I could join this challenge, but I'm no good at organic modeling. I'd never be able to recreate her.
-
Here is my try at it
-
i don't have the time right now to draw all the details/fine tune etc. but here's 5 minutes worth of an idea
(if you have suPRO)
****[edit]- and i guess i'll add that i'm lobbying for dynamic component usage here.. i've lately started to realize that DCs have more/less been sold as one thing when they are in fact more than making a cabinet with different sized drawers (or whatever).. they can be used as a calculator for actual drawing as shown in this example (or i like to think of them as the ability to quickly produce very specific plugins for the task at hand?)
i think if more people started using them and/or their popularity increased then the SUteam may be more inclined to update/add functionality etc.. -

It's not organic modeling, it's CAD Modeling

Yes Dynamic Components are very under used!
But you must make some efforts, it's not "Spontaneous generation" ! -

But you must make some efforts, it's not "Spontaneous generation" !right, the geometry has to be there in the first place, but, with little bit of creativity, you have all the geometry you need..
lines can be hidden unless needed and you can use copies to generate new lines etc..
pretty much the main problem with DCs right now is that you can't control lines/faces unless you make them separate components in which case they lose their ability to make faces in the main component. -
Jeff,
How does it work? Interact doesn't do anything? I never use DC's so forgive the ignorance.

fwiw, i never use interact..
this version is just the raw version of how i'd use it as a calculator while drawing.. i'll make a more polished version w/ user input etc in a little bit..
-
This calculator will works only with the Loopita Bonita Lounger model or it's will be universal?
-
Not quite identical but I enjoyed the actual maths more than the model. I'll finish the cushions tomorrow if I've time.
Make for a nice Render This also
-
Rich, that looks great, I never use DC's so I'm stumped.
I want to use some sort of stringer but cannot find one that strings perpendicular to the path...anyone know if one exists?
-
re: the DC.. look at the screen shot --
those are all the functions i used showing in the component attributes dialog..
i made the rib and set it's axes to 2 1/2' above it as i figured i'd make a 5' inner radius.. (this is changeable if you want and i'll include a height example in the user friendly dc i make of this)..
i put 120 for the amount of copies meaning the rib component will be copied 120 times.. for rotX (rotation around the X axis) i put:
RotX=0+copy*3
which means the first rotated copy will be rotated 0º then every copy there after will be rotated 3º (and 3º * 120 copies = a full circle)for position X (position along the red axis), i put:
PosX = 0+copy.35"*
which means the first copy will not move sideways along the red (or 0) then each copy after that will shift .35" to the right along the red.. -
I never thought to use a Ruby function. Great idea Jeff. You could probably get the same result by doing the maths then manually moving/rotating the second instance relative to the first, then using AdamB's xformclone.rb which appears in this thread. Obviously, this can be done on the free version.
[Edit] Yes...works a treat. I've got RSI now, though.
-
I'm going to try to model this for FormFonts. In order to save polygons I'm going to probably ignore stuff like the doubling up of ribs where each section joins the next; and just do a straight array like the ones posted so far.
However, I would like to get the geometry right...and it's more complicated than at first sight. You'll notice that the ribs are level at the beginning and end...and also at the TDC...but they they are noticeably banked (like a real rollercoaster) as they go up each side of the loop. That's another function that will need to be calculated.
Once the ribs are looking correct; rather than building separate rails, it's probably going to be easier to simply draw the rail profiles on one of the rib components and P/P them to join onto the adjacent one. That will probably require unique components for the flat section at either end, as the rails on the loop are going to have to be slightly skewed. -
I see that there are segments of approximately 120 degrees. And they are twisted. This is obvious. Your tests are similar, but incorrect, because the segments are the horizontal and rotated about two points

Strange that I should get the same result then.
-
I was talking about the first examples
. your test is really similar -
Ah! I misunderstood. Great model BTW.
I could see that the actual construction was made up of maybe a dozen sections of 8 or 9 ribs each, so I decided to just do a single array of 96 ribs.
If anyone wants to try this from scratch (actual dimensions unknown):-
Make a single rib component 30" wide.
Make a 5' disc at the side as in alvis's image...to get the centre of rotation for the loop.
Make a rotated copy of the rib at 3.75 deg, then using the Move tool on the rotate handles, rotate it by -0.7 deg.
Activate the xcopyclone.rb until your finger drops off or you get a complete loop...whichever comes sooner. -
not bad not bad
