Abstract [en]

Dynamic locomotion in computer games is becomingmore common, but is still in its cradle. In this report weconduct an investigation into whether gait oscillators couldbe used as an in-game technique to generate dynamic locomotionin realtime. We tested this by using an industrialquality physics simulator to simulate a biped and aquadruped (humanoid and salamander) and measure quality,runtime and memory usage. The tests show that abiped need some balance system in order to walk indefinitely,while the salamander managed to walk properly withonly minor defects. Memory allows several thousands ofinstances while runtime allows up to a thousand instances.This leads to the conclusion that it is a cheap system, suitablewhere the quality is secondary to number of instances.

Abstract [sv]

Dynamisk förflyttning i datorspel blir allt vanligare, menär fortfarande i sin vagga. I denna rapport genomför vi enutredning om ifall oscillatorer i form av ett CPG-systemkan användas som en spelteknik för att generera dynamiskrörelse i realtid. Vi testade detta genom att använda enfysiksimulator av industrikvalitet för att simulera en tvåfotingoch en fyrfoting (humanoid och salamander) och mätakvalitet, tidsåtgång och minnesanvändning . Försöken visaratt en tvåfoting behöver något sorts balanssystem för attgå längre sträckor, medan salamandern lyckades gå med endastmindre defekter. Minnet tillåter flera tusen instansermedan tidsåtgången tillåter upp till ett par hundra instanser.Detta leder till slutsatsen att det är ett billigt system lämpligtdär antalet instanser är viktigare än kvaliteten.
