Epic Games today announced its Epic Citadel App is now available from the App Store. The app showcases the technical capabilities of Epic’s Unreal Engine 3 on iPad, iPhone and iPod touch.
In Epic Citadel, players navigate through a castle using simple controls and Multi-Touch gestures. Epic Citadel's visuals, special effects, and environment are part of Project Sword, Epic’s newest game -- an action role-playing adventure game exclusively for iPad, iPhone and iPod touch developed by Epic’s studio, Chair Entertainment, creators of the Xbox LIVE Arcade games Undertow and Shadow Complex.
A small team of Epic’s programmers, artists and testers created Epic Citadel in just eight weeks of development time.
Features of Unreal Engine 3 for iOS platforms (iPod Touch, iPhone, iPad) include:
Bump offset mapping - Also known as parallax mapping or relief mapping, bump offset mapping enhances the visual appearance of stone walls and rocks providing intricate textures.
Normal mapped architecture - Brings stunning detail to bricks and ground surfaces within the environment.
Texture blending with painted weight maps - Refines nuances on roads and terrain, making them rich and lifelike.
Global illumination - Unreal Engine 3’s built-in global illumination system, Unreal Lightmass, provides realistic lighting and shadows with minimal development resources.
Dynamic specular lighting with texture masks - Helps create authentic cobblestone roads and vivid reflective marble surfaces, while lens flares and light coronas add dramatic emphasis when panning across light sources.
Real-time reflections and animation - Environment mapping enables real-time reflections on objects such as the statue inside the cathedral. Dynamic movements of trees and banners are made possible through the use of vertex deformation and skeletal animation.
