Target & Hardware

Wild Animal Species (17 Classes) 3D RIGGED

Species

Panthera pardus orientalis: Articulated 3D feline rig with procedural rosette pelt, stalking gait & reflective tapetum eyes.

Timeline Progression Guide

• t = 0.0s to 1.0s: Animal is outside PIR zone ($d > 8\text{m}$). Camera & light are OFF (Sleep).
• t = 1.1s: Animal crosses into PIR zone ($d = 7.7\text{m} \le 8\text{m}$) → Light switches ON → Camera wakes up!
• t = 1.2s to 4.5s: Camera streams frames → Backend runs 3-layer servo math → Gimbal follows animal.
• t ≥ 4.5s: Deterrent sound fires → Animal flees crop area.
