    Glacier Engine 1

    Concept »

    The Glacier 1 engine was created in 1998 by IO Interactive, and have been running most of all IO Interactive's games since. The Glacier 1 engine is by 2011 retired through the announcement and upcoming release of the newer and stronger Glacier 2 engine, in the latest franchise Hitman: Absolution.

    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
