Calibre Destruction Engine

Calibre Destruction Engine is a free-license destruction engine, created by DECA. It first appeared as an intregated part of the Wartech 4 engine, but was later developed as a sole secondary physics engine to be used by every developer.
==Features==
*Real-Time ballistic calculations
*Pin-point projectile accuracy
*Microdestruction & cover destruction
*Gravitational pull
*High speed texture rerendering
*Projectiles motion blur & shadows
*Dynamic illumination
*Structure impact calculator 
*Enhanced blast radius & effects
==Destruction==
The main feature of Calibre is the destruction physics. Calibre features an unique non-scripted destruction ability, which is possible due to the gravitational pull and structure impact calculator, as well as the microdestruction. The way it works is that all objects that are destined to be destroyed have a gravitational pull above them, which has a certain amount of "weight". For a wall to collapse, it's "strenght" has to be lower than the "weight". Then the structure will collapse. 
For the strenght to decrease, the structure can take damage from explosives and bullets. While explosives tend to destroy the structure completely, bullets also have the chance to weaken it. If a bullet hits a wall, it leaves a hole in it. Each hole takes away a bit of strenght, until the weight surpasses the strenght and the structure collapses. 
While walls and pillars mostly have gravity on them, whole buildings also have them. The buildings also collapses when it's strenght is gone. Only for a building, the strenght is measured over multiple pillars and walls. When most of them are destroyed, the building will collapse and leave a pile of debris behind, but can also have big junks of rooms of that building still accesable on the ground.
==Games using Calibre==
*All games using Wartech 4
**i.e. Warzone: Evolved, Dark Half 3
*Empire of Earth
==Trivia==
*While Calibre is intregated in Wartech 4, Dark Half 2 and Blackstreak don't use the destruction in the same scale as in Warzone and other future titles.
