## Abstract

Game development in 3D is mostly done by characters, items and the environment. Game items such as character weapons modeled in 3D will be the attraction of a game. In this paper, spear motion as a game items is modeled in 3D. Nonlinear Equations Six Degrees of Freedom (6 DOF) are used for mathematical models of spear motion. The parameters studied in the motion model are: geometry, mass and aerodynamics. Spear aerodynamic parameters were analyzed using the Datcom method. Numerical simulation of mathematical models of spear motion with variations in the initial velocity of the throw and the direction of the throw. From the results of numerical simulation, the maximum range R = 131.7 m at the initial velocity V_{0} = 40 m/s, the direction of throw (angle θ_{0} = 35 deg, angle φ_{0} = 10 deg, ψ_{0} = 0 deg). And the maximum height H_{max} = 12.18 m is achieved at the initial velocity V_{0} = 20 m/s, direction of throw (angle θ_{0} = 35 deg, angle φ_{0} = 40 deg, angle ψ_{0} = 0 deg).
