With CPU cycles ever the more generous and efficient, modern shooters have had little reason not to incorporated bullet penetration into their physics models. However, the inner workings of such mechanics are never fully revealed, leaving most to spray at wooden doors, sandbags, windows... OK, well anything solid really, in the hopes of getting a lucky hit on an opponent.
With ARMA 3, we finally get a look at just how accurate a ballistics model can be... and the answer is very.
YouTube user Dslyecxi put together an almost 14-minute video that painstakingly goes over the penetration profiles of several weapons from Bohemia Interactive's recently released FPS, including 5.56mm, 7.62mm and .50-cal rifles and a .45-cal SMG. Dslyecxi uses a custom script to not only paint the trajectories of the bullets as they leave each weapon, but to colour-code changes in velocity as well.
Along with firing the weapons at different materials of varying thicknesses, he also unloads at obstacles at various angles, to show the effects of deflection.
Unsurprisingly, the .50-cal performs the best, but I was surprised at how poorly the .45 SMG performed — for some reason I thought it'd do better.
