The paper develops a 3D model of social coordination in fish using real behavior data and validates it through a closed-loop virtual reality system.

Real rummy-nose tetras follow a projected, anamorphically rendered virtual conspecific in a low-cost open-source 3D-tracked VR bowl, largely matching its speed and depth; a moving sphere elicits weak following.

This paper introduces a theoretical framework for growth-driven collective behavior inspired by plant tropisms, analyzing dynamics of single and interacting organs.
