A tiny spare-time project with some strand and particle parts. I rendered it in Redshift with some little comp-work in Fusion.
in sum: take the normals from the obstacle with some crossproducts and random values for the direction vector. In frequence i add points to the position of the parent points to generate the brunches.
really simple stuff: Curved animated brunches. Strand dynamic framework (verlet) uses for the tentacles. Balls done with rigid bodys, covered with a dynamic mesh generated with the polygonizer. Cached all out and shifted into renderscene(s).
