Pivot Animation
Madelyn Westfall
I'm trying to create a 'swinging' animation using a rectangular prism. The animation is very basic: The prism is going to swing back and forth, like the arms of this robot toy. I need to use the above matrix.
I just need help figuring out a series of values for theta that can be plugged into this matrix in order to cause the rectangular prism it will be applied to to swing back and forth, like in the image linked to above.
I'm very new to blender and animation, so I'm not sure how to proceed >
When you animate, it doesn't take the 3D Cursor into account anymore, it will rotate around the object origin, or around the bone to which your object will be parented (or empty as suggested by Nicola Sap). So if you want your door hinge as a pivot point, you need to change the door origin and put it on its hinge: in Edit mode, select a hinge vertex, press shiftS > Cursor to Selected, then back in Object mode, press shiftctrlaltC > Origin to 3D Cursor (for 2.8: Header menu > Object > Set Origin > Origin to 3D Cursor). Then create your animation, your door should pivote around its hinge.
I wish to move the pivot point in Animation. The facility exists in the "Transform Components" dialog box, but when you re-position the pivot the component you are trying to move stay's put, although a move angle is indicated.
I am trying to animate the opening and closing of a carton from a flat blank so need the panels to rotate around the crease lines (panels are individually modeled components and do rotate in the model). At the moment the pivot and move points show in a random position on each panel.
Hi,
From what I understand from your basic issue, using the Pivot tool, you are setting the PERMANENT pivot.
Using the Transform tool, you can then animate your drawing. If you need to temporarily move your pivot, do it with the Transform tool.
If you move the pivot again using the Pivot tool, you are changing the permanent pivot which recalculates all of your animation from this new pivot position.
Does that help you in any way?

Thanks for his input clarity in this discussion Marie-Eve.
I think that an oficial video tutorial that unify clearely all concepts about using pivots, showing, what the user can do, and what never can do in each instance of using pivots in drawings and symbols, copy and paste, with and without using setting the pivot on all frames, reseting pivots, using the paste special - update drawing pivot, adding template contents with pivot and adjust it to use the same pivot that are in the previous drawings, copying these pivots in the parent symbol and how manage the drawing parts in camera view using the transform tool and too using the temporary transform pivot, not the pivot tool itself, that popping out if it is placed in a new location, setting the peg pivot with rotate, scale or skew tools not with transform tool, can be fully used by all users for understand clearely and definitely this important aspect of the rigging and animating puppets process. Thank you very much.
Best Regards.

Hi,
You are welcome.
A video about Pivot will be published shortly on the Animate and Animate Pro How To page once we start teaching how to build cut-out puppets.
I will make sure to transmit your comments to the instructor.
Also, using symbols to build a cut-out puppet can be handy, but to animate in production can slow down the process a little bit and limit the possibility of morphing. You cannot morph between 2 symbol cells.
Make sure not to embed symbols inside symbols, you will cause yourself more headache than good.
Good luck!

Hi,
If you use Drawing pivots, you can duplicate your drawing using the DUplicate Drawing function and set a new pivot for this particular drawing.
That should do the trick.

Pivot Animator is designed to be a user friendly way of creating 2D stick-man animations. The basic concept is that stick figures can be easily moved and positioned by dragging handles. An animation is made up of frames added to the time-line, which are shown at the top of the screen. This can require more time to create a smooth animation than it does in flash for example, because Pivot doesn't support frame tweening. This however makes Pivot very easy to use and gives the animator full control over figure movement.
Due to licensing restrictions we cannot make latest version (4.2.6) of this great application available on rollApp. Please, visit pivotanimator.net to download latest version of the application to run on your computer.
Its good but not that much . I face problem in saving , adding background and opening animation , moreover the animation is too fast . I only like it because it is easier than other animation making apps.
great for chromebook users (probably 99% of these people) with all of the features of the original. great for my animations or if i just want to mess around a bit. also you can add figures other than stickmen
I have used this app and it is very good for beginning animators. it does not crash for me so maybe get a better internet connection, this is not 5 stars because there is no tutorial on the page. for a tutorial go to you tube that is where I learned how to use this program.
Good tools for learning about animation but not very good that is doesn't allow you to save your work without having to pay. Doesn't help they hide that fact you cant save till it too late. Feel a little dishonest.
But how can I have a consistent pivot point when the size of the caracter needs to change ? For exemple :
when my hero is jumping, his legs are getting closer to his body so the player is getting smaller. What can I do to avoid those weird movement between frames ?
Now in left top corner we can set how sheet should be sliced. Automatic one is quite good, but sets also automatically pivot point. Best pivot is probably left-bottom or center. Hit slice and You will have frames.
Pivot Animator (formerly Pivot Stickfigure Animator and usually shortened to Pivot) is a freeware application that allows users to create stick-figure and sprite animations, and save them in the animated GIF format for use on web pages and the AVI format (in Pivot Animator 3 and later).[1]
The first version of Pivot Animator had several software bugs. Stick figures were limited to one type of stick figure, the default stick figure. Animations could be saved in the PIV (Pivot Project File) or exported as Animated .GIFs (Graphics Interchangeable Format). Users were given few options of image optimization, compression or resizing when saving their animation. This was one of the first animation programs available on the computer.
The second major release of the Pivot Stickfigure Animator. This version implemented the 'Stick Figure Builder', which allowed users to create their own stick figure designs saved in the STK format. This allowed a much wider scope of animation choice for Pivot users. It also fixed a few minor bugs, added the buttons to the main interface to bring a stick figure in front or behind other figures, and could automatically check to make sure the user didn't lose any unsaved projects.
This release was sent intentionally to the Pivot Animation groups for testing but the Beta was leaked from various unofficial sources to the general public. There was an improved interface, with new icons, a better default stickman with a thicker body, and a reorganization of the features. New features included the ability to import any image into the animation. Another added feature was the ability to have multiple backgrounds in an animation. When a user saves a .piv file, the frame rate is saved with it.
Pivot 4.2 was announced on December 23, 2014 followed by a beta release on January 1, 2015.[3]New features include copying and pasting selected stick figures and sprites, a transparent figure builder window,[4] and the ability to export images in the Scalable Vector Graphics format.

This week the Prep-2s started off easy with an app called Easy Animator, the Grade 3-4s looked at Pivot Animator and the Grade 5-6s started their unit on Video Production with making screencasts (or instructional videos) using the free web based tool "Screencast-o-Matic".
Really, you could get easier than this. This is basic app, made by Crayola, that lets the students choose a character, a background and then punch in some predefined movements to have the character move in sequence. It's a perfect introduction to how animation works without having to learn any difficult concepts.
There is also another layer to this app that we haven't used yet, but I would love to in the future. You can buy a kit that allows you to manipulate a puppet, record the movements, and program that into the app. The video below shows how this works:
As I say, a perfect introduction for the younger kids on how animation. Below is an example of what some Prep kids did. Note, there is the facility (similar to PuppetPals) for the students to record audio over their animations.
It's important to stress to the students - in my case the Grade 3-4s doing this - that to create the illusion of movement, the changes between frames needs to be very slight. Small movements, and LOTS of frames. Otherwise what you get is a lot of figures flashing on the screens in random positions.
I talked to them about the onion-skin feature. That "shadow" that shows where the previous frame was, so they can get an idea of what kind of movements they should be looking at. We also looked at creating backgrounds from taking photos, as well as playing with colour and opacity.
