[Obsolete] BZ__Animation (divider for flight path)
-
I used this workflow a couple of days ago and it worked well. But I tried to re-create it today and I cant seem to get the "Polyline divider for animation" choice, just the Polyline choice after I weld it all together. If I go into the Draw - Bezier menu and select the Polyline Divider for Animation is just allows me to create a new path which I dont want. Any ideas?
EDIT:
I found the problem. It was with one of the corners I had filleted. Works fine now thanks. -
Updated version, managing more accurately the rounding of segment length, avoiding the last segment to be too short in some cases. Also, the first segment will respect the given length (but the last one may not).

Bonjour Fredo, Hi everybody,
First I have a (probably silly) question.
How can I make that rounded BZ_Animation curve you are showing into the first post??
So far, I'm only able to produce angled polyline..Secondly, it is for a request.
I have found of a great interest to use this BZ_Animation in conjunction with Chris Fullmer's Component Stringer (and ChrisFullmer's ShapeBender actually to curve the "animation line".
-)But for me It is lacking various possibilities for "acceleration" (from various parabolic curves ... heyhey, my school knowledge is so far now)
More often this unique acceleration is too "strong" for my purpose..
a little study
dreaming HelixStairs using in conjunction: Bz_Animation + ComponentStringer + FredoScale =
Sorry dear Fredo to ask you anything: You are already giving so much...

Hi Simon, about your question... From Fredo's first post:
@unknownuser said:In practice, the most common usage is to Convert an existing Polyline or Spline to this type of Animation curve, via the contextual menu.
Draw a polyline-->select it-->right click and choose "convert to"-->"polyline divider for animation".

,
so simple (and it was written black on white
), thank you. This is a very good first point. Because I was using a complete Shape Bender process to achieve this until now..(another picture of my "dreaming stairs" on which you need to start with very small legs and growing up, you get to finish with very tall ones
. Maybe the stairs of life: we always do the same, just incrementing by steps.... OK it's enough.

You are right, it should be possible to actually to map the variations on other mathematical curve. This would of course require more parameters. The one that springs to mind is the S-curve (also called Logistic curve) which provide slow then growing then slowing down acceleration.
Let me check if I can isolate the formula so that it is easier to try various models of formula without multiplying the number of plugins.

Remember my rustic plug where you can cook any formula
Thank you Fredo to listen and to agree ; thank you Pilou to bring your quote..I feel right in such a good place...

Hi Sketchy laborers
I want to use again BZ__Animation in conjunction with Component Stringer.
My purpose was to draw an animated straight edges with an exact length. It is silly but I hadn't found how to reach this precise length via the VCB!!
After some tries,I had used two perpendicular guide lines spaced from my length and inferences to draw my animated edge!
Do I have missed something?

Here is my reverse curve script.
Hi Pixero,
Just to say, your reversecurve.rb script didn't work properly for me (it didn't appear in Sketchup 7). So, with your permission, I dug around in the script and fixed it so it should work for Sketchup 7 users. I've posted it here. Enjoy, and thanks for this script - it's a life saver! (and the only one on the web..)

Hmm...it worked fine for me with SU 7.1.
Are you on a Mac?
