Simulation can show the movement of the object in space to obtain realistic display of their behavior in the real world. To create simulations it is necesseary to have graphically as stronger and powerful computer (depending on how much detailed the simulation is running), and of course some of the programs to create 3D objects and animations, but in this case we will be using Blender. The goal of this diploma thesis is to create models and simulations of ragdoll movement with the help of Blender game engine, and also make the same simulation in 3ds Max program so that we can compare these two projects with their different parameters and to visually compare. It is important to know that the transformation of the ragdoll will only affect the mechanical force, as opposed to figures with armature (skeleton) where the animator has the ability to manually control the movements and potencialy problems that can occur. Creating detailed ragdoll is a very tedious process, therefore we will in this thesis use a very simple model, made up of the most basic elements. All set parameters and performance parameters of the computer will be described in detailed steps. Simulation will further enhance the visual texture and appropriate lightning. Testing will be done on a desktop computer.
