This blender experiment is based on the curve generation python script from my erlier post - Ths time I added keyframes to the locations of the bezier curve vertices and their handles.

Keyframing a curve vertex from a python script is pretty simple. All that is required is calling the keyframe_insert method on the point object and specifing the path to the attribute that should be keyframed.

For example

b.bezier_points[i].co = (1,1,1)
    b.bezier_points[i].keyframe_insert(data_path='co')

inserts a new keyframe for the position of a curve vertex at the current frame of the scene.

to change the frame i used

bpy.context.scene.frame_set(framenumber)

For this blender 2.80 experiment I created four bezier curves using the blender python api. There have been some changes in the api, but porting existing python scripts to 2.80 is pretty easy - the main changes required for older code to run is how the objects get added to the scenes, because of the new collections in blender 2.80

to run a python script open a texteditor and run a script with ALT-p

I haven't used the animation nodes addon in a while - so I dug it up and created a new animation with it. It took me a while to get it running on my box due to python installation absurdities but I finally got an 1.6 up and running in my blender 2.78 installation. For this animation I used an empty list of vectors and filled it with random vectors generated by a vector-wiggle-node. I then used these vectors to create curves. Since I wanted to create a knot I used a second loop that creates several of these splines and adds them into a spline list. This spline-list is then added to a new object and rendered.

For this animation I used a pyhton script node to generated 3D coordinates for a closed curve you can download the blend file here

For this animation I used the "Network From Particles"-Template of the Animation-Node-Addon to add splines between clusters of particles

For this animation I used the python script node of the Animation-Node-Addon to create a list of coordinates for a bezier-curve.

I used a uv mapped curve with a ring texture in cycles to create this animated light-stripes

For this experiment with the cubesurfer-addon by pyroevil, I made a particle emitter follow a curve path and used particles that don't react to gravity
