Overview

The Glacier 1 game engine was created by IO Interactive in 1998 and was used publicly for the first time in the year 2000, with the release of IO Interactives first game, Hitman: Codename 47. With the announcement of Hitman: Absolution the new game engine Glacier 2 was set to be a "clean cut" from the Glacier 1 engine, thereby retire-ring the 12 year old engine with over a handful of succesful games.

Facts

Creator:

I.O. Interactive

Operating Systems:

Windows-, Xbox- & Playstation systems

Number(s) of games:

8

Graphics API:

OpenGL, DirectX

Programming Language:

C/C++

Technical information

General features:

Object-Oriented Design, Plug-in Architecture, Save/Load System with more.

Scripting:

A flexible, object-oriented script that can be assigned to custom-programmed objects and thereby enable them to participate in the AI-state machine. The usage of scripts allows behavior to be changed at runtime. The language is event-driven and state-based.

Artificial Intelligence -AI:

  • Pathfinding
  • Finite State Machines
  • Decision making
  • Scripted hierarchical 3D path planner supporting teleports and special moves including: (Climbing latters, stairs, going through holes and so forth...)

Different physics:

  • Basic physics
  • Collision detection
  • Rigid body
  • Vehicle physics
  • Advanced collision detection - Precise at polygon level or a simpler level of detail if needed
  • Advanced dynamics - Real time calculated cloth and hair on character, plants, hanging bridges etc.
  • Rigid body dynamics - Making it possible, to make objects and rag-dolls very realistic
