  1. 3D Game Engine Design for Portable Game Device

  2. 3D Game Engine List • 대표적인 상용 게임엔진 • Quake1,2,3(id Soft) • Unreal Engine(Unreal Tournament), Unreal2 Engine • Lithtech Engine(Jupiter, Triton, Talon, Cobalt system) • 기타 유명 해외 게임엔진 • Genesis3D • Power Render3D • Fly3D • Crystal Space • Revolution3D • ETC.. Sogang Graphics Lab

  3. 국내 게임엔진 개발 현황 • 몇몇 게임 엔진들이 출시되어 상용화 되어있음 • ‘블루’(판타그램) – 킹덤언더 파이어, 샤이닝 로어 • ‘왕리얼’(손노리) – 화이트데이 • ‘Axis’ – 자체 개발한 3D엔진으로 온라인 게임Axis개발 • ‘Xtasy’(조이온) – ‘Gears’에 사용 • ‘Game Infinity 3D Engine’ – 한국 게임종합지원센터에서 국내 개발업체에 보급 • ‘Lipton GL’ – 세고 엔터테인먼트 • ‘Dream3D’ – ETRI개발, HCI2002 시연, 발표 • 기타 60여종의 국내 게임 엔진들이 개발중 Sogang Graphics Lab

  5. 휴대용 게임기 • Nintendo GameBoy Advance • 16Mhz 32비트 ARM RISC + 8비트 CISC • 240x160, 32,768색, 2.9인치 반사형 TFT • GamePark GP32 • 순수 국내 기술로 개발 • S3C2400X01 99MHz CPU, 3.5" TFT, 320x240, 65,536 칼라 • Bandai Wonder Swan Color Sogang Graphics Lab

  6. 휴대용 게임기의 특징 • 작은 액정 • GP32의 경우 3.5인치, GBA는 2.9인치 액정을 사용 • 320x240 정도의 낮은 해상도 • 낮은 사양의 CPU • GBA : 16Mhz RISC칩 사용 • GP32 : 99MHz RISC칩 사용 • 저전력, 저발열 요구 • PC와는 달리 GPU와 CPU사이에, 외부 BUS를 통하지 않기 때문에 효율적인 처리 가능 Sogang Graphics Lab

  7. 휴대용 게임기용 3D Engine • BlueRoses-Raylight Studio 개발 • - Motion capture animation- Affine texture mapping- Camera animation- Skeletal animation- Skinned characters- Linear key interpolation for smooth animation- Morphing support- Scalable engine for either internal rooms and wide open space- LOD- Hierarchial hidden polygons/object remover to reduce overdraw.- Glows, Lens FX, Coronas- Particle systems- Texture animation support- All mapping method supported: planar, sphere, face, cylindrical, unwrap, box, tiling, mirroring…- Multicamera with dynamic FOV- Automatic maps arrangement in "texture memory" to optimize pipeline rendering- Possibility to mix 2d and 3d together having 3d polygonal scene with custom 3d sprite technologies already used in our current projects • GS3D - Graphic-State 개발 • A3D features a true 6-degrees of freedom texture mapped 3D engine. • Lightning fast 2D and 3D Point processing. • N-sided polygons. • Full perspective correct texture mapping on all surfaces. • 2D scaled sprites support - multiple rotations and animation frames are supported. • Hardware sprite overlays. • True 3D collision. • Mesh animations. • Import models directly from Lightwave. • Import Scene files directly from Lightwave and play them back within the engine. • Hand-optimised 32bit assembler ensures maximum performance for all low-level functionality. • Support for 1 to 4 players via link cable.

  8. 요구되는 기본 기능들 • Standard Triangle Rasterization • Hardware T&L • Z-Buffer Rendering • 6 Degrees Of Freedom • Texture Mapping, Lightmap, MultiTexture, Shadow • Environment Mapping(Bumg Mapping) • Perspective Corrected Texture mapping, Mipmapping • BSP/PVS, Landscape • LOD • Character Animation(Vertex Morphing or Vertex Skinning) • Full 3D Collision detection • Particle system • Mirror, Lens Flare, Fire, ETC.. Sogang Graphics Lab

  9. 추가적으로 요구될 사항 • SGIX_SHADOW Extension을 이용한 shadow생성 • 1차원 텍스춰의 Dependent Dot-Product Texture기능 • Texture Rectangle(Non-power of 2 size Texture) • Stencil Buffer Sogang Graphics Lab
