Animation?

I have never done animation in Grasshopper. What would be the best way/plugin to animate an object to:
-follow a path of points/curve (and control its speed somehow as it goes from point to point or curve segments)
-be able to rotate this object (in all directions) through a vector input in each point (possibly controlling speed of this rotation too)?

You can use the sliders in grasshopper to make animations. If you right click on a slider there’s an “animate” button which outputs images while it’s going through the slider. You can then combine those images into a video. This has been working well for me so far.

For camera movement you can use the plugin Horster.

I appreciate your reply. Would you know how to combine the sliders so I can have move and rotation in one?

Yes. You can use 1 slider to control different things at once. If you make a slider going from 0.000 to 1.000 and then use the remap domain component to control the different inputs of the move and rotate component. Like so:

Thank you so much!

Hey !

I’m new to this forum but I’m getting very familiar with animations in Grasshopper.
Here is a simple definition for a very simple multi clip animation (move then rotate) dictated by only one slider (to animate).

There is a more presice way to actually work with duration of each clips in seconds (I will make a tutorial about that when I got some free time), but this is a good way of approaching multi clip animations in Grasshopper.

Notice that I use a (great) plugin from Daniel González Abalde (Riched Graph Mapper).
This very computer cannot save the graphs into the definition so you might need to rebuild the definition by yourself after installing the plugin (this computer is sheeeet) :slight_smile:

If you’re interested to see what can be done in animation with Grasshopper, you can check my instagram account.

Thanks for your reply Maes. Your animations on Instagram are amazing, looks like I’ll have to make an Instagram account to follow :slight_smile: One question, how long did the animations on your Instagram take to render/export?

I notice you guys don’t make use of compounding transformations. Just so you know using X outputs and compounding will save you lots of computation time on larger animations. Making transform data doesn’t take much computation, then you just transform the object once rather than for each transformation. (note the compound component description says “combine two transformations”, but this is a typo as it combines as many as you plug in, but keep in mind the order that you plug them in is important to how you want the transformation process to work)

Hugely helpful, thanks! Is there any way to gauge the computational savings?

@Michael_Pryor
I didn’t really know about that x output !
Thank for the advice, I’m going to try that for the next ones ! :raised_hands:

@sarka.harrington
Thanks ! For the render it depends… Right now I’m only using the rhino rendered viewport (don’t know how to use cycles render through “animate” in grasshopper yet).
So this means they are kinda bad renders :joy: and that it’s kinda fast to animate. But some of them actually took 5h (the swirling thing one) as pipes are heavy to compute and that the loop is around 15 sec long :slight_smile:

You can also get pretty sweet animations using a modified Arctic display mode. :slight_smile:

Thanks for your reply, I love Rhino arctic mode. In order to get GH animation in arctic mode, do I have to bake the geometry into Rhino? Or can I somehow render arctic mode from GH without baking geometry?

Hi Sarka,
Right now I’m not on my Rhino 6 machine, but I believe you can do that by sending your geometry to the Custom Preview component and feeding it a material name into Shader input, maybe via Value List. Don’t forget to disable preview of the rest of your Grasshopper code.

I can check later if you struggle to replicate.
