After happening across the P5Sunflow library for Processing, I just had to put together a sketch that used it. Since I’ve been playing with the Phys2D library recently, I figured a nice little physics simulation would be the most appropriate direction for a test sketch.

As the title suggests, this little 600 frame movie took rather a long time to render. I think I need to invest in a new machine before I make any more attempts to render pointless, but beautiful movies.

You can have a look at a realtime version of the sketch over here and the source for the P5Sunflow version can be downloaded here.

Started playing with Phys2d recently while researching 2D physics engines. As every man and his dog seems to be copying Crayon Physics at the moment, I thought I might as well go ahead and do the same.

Just draw with mouse and the objects will drop into the scene. I’ve not added any checks for complex polygons, so try not to draw any shapes which intersect themselves as they tend to freak out a bit. Press R to reset the scene.

Cloth Simulation

I happened across this rather nice spring physics library for Processing, so I thought I’d try making a simple cloth simulation to see what it was capable of. Turns out it’s really easy to use and works exactly as advertised. I think it’s time for a little more experimentation.

Instructions

Drag any of the vertices around to control the “cloth”. Hold down the space bar while releasing the mouse button to “pin” the vertex.

Source

You can grab the source code for this if you really want to. You’ll need the traer.physics library if you want to run it in PDE.
