Animations using build123d

[Miguel-N]

Is there a way to make good animations using build123d?

I'm interested in animating mechanisms.

So far, i have tried to just move a box using the move commands and view the animation in the ocp-vscode viewer, but i think this is not the right approach, as the movement doesn't feel fluid.

Animation using build123d and OCP CAD Viewer

Previously, I tried a similar approach to animate a fourbar mechanism using FreeCAD to import step files and updating the positions of the parts based on the results of an optimized complex algebra quick solver i made, and the results seem fine, but when the complexity of the step files increases, the visualization is very buggy. From what i could gather, this is due to the backend FreeCAD uses to render the models.

Is there a viewer that works with build123d that would give me fluid animations?
Or is there an animation file format that i can use to export an animation using build123d?

Any help would be appreciated.

You can try https://github.com/bernhard-42/bd_animation, it uses the threejs animation system for fluid animations. I added some gifs in the Readme to show some results
It needs to be installed from github, there is no pypi lib yet.
