toxiclibs pumpkin function
since helloween is comming nearer I made a processing sketch that generates a 3D pumpkin using the toxiclibs mesh builder. Generating a pumpkin-shape isn't very hard to do when using polar coordinates.
I use a sin of the phi angle to make the shape a litte bit more flat on top and bottom
and than i subtract the absolute of a sin of the tetha angle to generate the segments.

Spikes and Bumps with Toxiclibs
My next toxiclibs surfacebuilder experiment generates spikes and bumps on a spherical surface

how to make a tentacle using processing and toxiclibs
the Toxiclibs are a very interesting collection of processing libraries. One of the libraries is called volumeutils and allows to use a volumetric space to model a 3D object.
I used it to generate a tentacle and export it as a stl file to make it printable on my 3D-printer.

In the setup method i define a volumetric space containing 100x100x100 voxel, a iso surface and a Triangle mesh (which is needed to display the object and export it later)

gfx = new ToxiclibsSupport(this); VolumetricSpace volume = new VolumetricSpaceArray( new Vec3D(100,200,100), 100, 100, 100 ); IsoSurface surface = new ArrayIsoSurface( volume ); mesh = new TriangleMesh();
