  1. Importance of Graphics

  2. Importance of Visual Sense • Graphics communicate the game through the eyes • Visual Cortex most massive system in the human brain • Hardwired to recognize objects, relative depths, patterns, etc. • Major target for immersion

  3. Graphics should provide • Images • Context • Interface

  4. What style? • Graphics need not provide state of the art realistic Images • It is important to link graphics style and game play

  5. Historic War Games & Realism • Goal • Present a war or skirmish • Put the player in the middle of the action

  6. Historic War Games & Realism • Result: Imagery of a realistic combat environment Typically combined with accurate representations of weaponry

  7. TF2 Pits two opposing forces against each other

  8. TF2 & Cartoon Shading • Pits two opposing forces against each other • Relates absurdity of the situation to cartoon-like graphics

  9. TF2 & Cartoon Shading • Root Unreality • Two teams build bases next door to each other • Extended Unreality • Significant Player Size Differences • Flying Soldier • Medicharger • Expanding Equipment

  10. DEFCON & Tactical Overview • Tactical Nuclear War Simulator • “Everybody Loses” • Player controls military forces • Destroy All Opponents • Protect Your Cities

  11. DEFCON & Tactical Overview

  12. DEFCON & Tactical Overview • In real situation, the commander-in-chief would be in a secure bunker • Commander can only see the overview map • DEFCON directly mimics this idea • Utilitarian Icons • Motion Paths • Alert Icons & Messages

  13. Potential Pitfalls

  14. Uncanny Valley • Humans are good at detecting human-like qualities • Especially when the target is barely human • Humans are also good at detecting inhuman qualities • Especially when the target is almost human

  15. Uncanny Valley The more human a representation is, the less human it may appear

  16. Uncanny Valley • Old games avoided this problem • No attempt to simulate real people with real‑time graphics • Modern games fall on both sides • Fantastical games may appear barely human • Realistic games may appear almost human

  17. Breaking the Fourth Wall • Derives from theatre • Occurs when a character, event, or image alerts the audience that they are watching or participating in an artificial event • Can also occur in computer games • Lens Flare • In-Game Hints • Easter Eggs

  18. Breaking the Fourth Wall • If done right, a player will accept it and move on • It can be entertaining • It may be appropriate for the game • On the other hand… • It can be distracting

  19. Misjudging Capabilities • Increasing rendering quality tends to increase the performance requirement • Increasing the performance requirement reduces capable players

  20. Misjudging Capabilities • Generally, a minimum of 30 FPS is required for smooth animation • 60 FPS is optimal • If the frame rate drops dramatically, player control and immersion similarly drops • Supporting multiple levels of hardware ensures all players can enjoy the experience

  21. Glitches • Inconsistencies can cause problems • Visible Levels of Detail • Misaligned Textures • Leaks • Shadows

  22. FINAL THOUGHT Perfect graphics cannot save a game with other problems
