Morphing Particle systems with Keyed Physics in Blender
Why Blender Stack Exchange recommends it
Blender Stack Exchange answerers point people to it when someone wants to morph between meshes with different vertex counts or make particles travel from one shape to another.
Recommended by 5 people across 5 different months, 2015 to 2023.
What it is
A 13-minute Blender tutorial by Blender HD showing how to use keyed physics in particle systems to morph one particle system into another. It covers transforming one object into another and switching between physics types.

Is your medical imagery made only of vertex (no planes)? If this is the case, you could morph one to another by using a particle system. add a particle system to each object, with the same number of particles create one additional object with the same number of particles add Physics > keys in the last created object's particle system, create a key for each of your medical imagery objects. Here is a complete tutorial about this. [this video] Hope it helps!

Morphing smoothly between two totally different objects with different vertex counts that also contain submeshes like text or single words is done more easily and efficiently by using particle systems and keyed physics. You basically "fill" your objects (the meshes with its submeshes which in this case are our letters) with particles and then use keyed physics to do the transition. I recommend the video tutorial from BlenderHQ which you can find here: Morphing Particle Systems with keyed Physics in Blender [this video]

One thing to try are keyed particle systems, example [this video] . *"for a novice user to do without a lot of confusion..."* I don't think so. Some practice is going to be required

I've found a solution that's pretty simple with the help of this video: [this video] Basically, create a controller particle system that manages other particles systems. Then create the first (1) particle system which keeps the leaves tracked onto the tree, using No 'Physics'. Then, create a second (2) particle system in the same position, which uses Newtonian physics and Brownian motion. In the controller cube, the first key should be attached to (1) and second key should be attached to (2) and you can use timing to set how long you want the leaves to stay attached. [LINK] It's an alright start: [LINK] One problem is, the leaves fall off all at once. The Brownian motion can hide this and make it

Have a look at the Harmonic Force Field [LINK] and look for "keyed particles" tutorials like this one [this video] to control the shape of particles.

Another way is morphing objects with Particle Systems [LINK] You can morph shapes of objects and even objects themselves (influnced by Explode modifier) with Keyed Particle Systems . From wiki [LINK] : The particle paths of keyed particles are determined from the emitter to another particle system’s particles. This allows creation of chains of systems with keyed physics to create long strands or groovy moving particles. You should only setup them in appropriate way so to make particles travel from one emitter to another. Step 1: Add objects and assign "simple" particles systems These systems don't do anything but providing particles needed for action. Because we need them to not emit in time

I am looking to achieve an effect similar to the particles shown in this tutorial: [LINK] BUT When the particles are in mid-air - whilst being affected by the force field, I want them to come back to the center to create a new shape or text field. I do not want to simply merge one shape into the next - like in this tutorial. [this video] Thanks in advance!

@3DSinghVFX Thanks so very much for your detailed explanation, and taking time out of your busy study life to help, greatly appreciated. Sorry for the delay had a family health emergency. What I'm trying to do is very similar to what is described here ( [this video] ) but without using the keyed particle setup and its limitations.

An old-school method would be to use Keyed Physics [LINK] , on matched particle systems. Perhaps the most controllable way is to set up 3 particle systems. One each on the source and target objects, and one on a dummy transition object. The source and target systems have normal particle effects, perhaps involving curve-guides or force-fields. The transition system is keyed between the other two: [LINK] I'm not sure it would be very helpful to share a file.. it's all in the settings, which will be very different case-to-case, and I won't pretend they aren't quite fiddly. There's quite a nice reference here [this video] . If you go this way and get stuck on a particular aspect, you can come back wi
