2. Diego Colombo colombod@di.unipi.it Game Elements A scenario, for sure! Some characters Something to interact with Something to see Something to ear

3. Diego Colombo colombod@di.unipi.it Production Pipeline

4. Diego Colombo colombod@di.unipi.it 3D Modeling for a game

5. Diego Colombo colombod@di.unipi.it Texturing Each model can have different materials Each material can have different textures Textures can be integrate with FX code

6. Diego Colombo colombod@di.unipi.it Just a note about FX FX are used to achieve realistic materials Water Reflection Glowing

7. Diego Colombo colombod@di.unipi.it Texel, Pixel, Area, and Real world measure Placing a texture is similar to put a sticker on a surface The sticker should be as large as the surface to cover One common assumption is that a 64x64 texture is 1 m 2

8. Diego Colombo colombod@di.unipi.it Texture and distance We can use a mipmap to obtain lower resolution image from a given texture Using lower tex when an object is far from the camera is to reduce memory allocation in favor of near objects

9. Diego Colombo colombod@di.unipi.it We need a skeleton The First step to get a acting character is to give it a skeleton This way defines matrix to be applied to each vertex biased by some weight

10. Diego Colombo colombod@di.unipi.it Rigging a character We need to define a tweak deformation Then we need to give a character some motion curves We would like to blend curves

11. Diego Colombo colombod@di.unipi.it Blending Typical approach for facial animation Number of polygons must match between blending shapes

12. Diego Colombo colombod@di.unipi.it Beware of interaction

13. Diego Colombo colombod@di.unipi.it MotionBuilder snapshot

14. Diego Colombo colombod@di.unipi.it Characterization Pipeline

15. Diego Colombo colombod@di.unipi.it Scenario tweaking Scenario should be as detailed as a detail is visible The more you tune and tweak the more cpu you can use to increase effects

16. Diego Colombo colombod@di.unipi.it Texture and Text 32 x 128 16 x 64

17. Diego Colombo colombod@di.unipi.it Prelightning with image based illumination Vertex contains information about illumination Illumination is achieved through global illumination from an image

18. Diego Colombo colombod@di.unipi.it Geometry details and illumination We can use vertex color illumination Vertex shaders can be used to pertubate the value

19. Diego Colombo colombod@di.unipi.it Daylight changes

20. Diego Colombo colombod@di.unipi.it Shadows Shadows should be smooth Static shadow can be faked Geometry must be corrected to support good shadows

21. Diego Colombo colombod@di.unipi.it Tweaking

22. Diego Colombo colombod@di.unipi.it Almost done

23. Diego Colombo colombod@di.unipi.it Level Completed Prelight + shadows + texturing

24. Diego Colombo colombod@di.unipi.it Low poly does not mean low detail

25. Diego Colombo colombod@di.unipi.it A beautiful ugly game (Matrix path of Neo by Atari) To low resolution models compensated by a rich texturing But an ugly character remains an ugly character

26. Diego Colombo colombod@di.unipi.it A beautiful ugly game (Matrix path of Neo by Atari)

27. Diego Colombo colombod@di.unipi.it Always Faking when possible We can use texture to simulate geometrical details This balcony is a “background” component With just a quad we achieve a great outcome

28. Diego Colombo colombod@di.unipi.it A game goes to the market if..

29. Diego Colombo colombod@di.unipi.it.. It holds the 4 B of success Blade Bop Blood Breast

30. Diego Colombo colombod@di.unipi.it Did anybody say camera? A game is a visual interactive story telling technique Director makes an actor a star Director tells audience what to see, think, and feel Director is the god of camera, he is the ruler of your world

31. Diego Colombo colombod@di.unipi.it Finding similarities..

32. Diego Colombo colombod@di.unipi.it Defining a standard palette Scenes must be “homogeneous” in colors Textures should use a common palette Textures should not mind about lightning Color definition is a key to emotion

33. Diego Colombo colombod@di.unipi.it Motion blur, another lesson Games are moving towards cinema Rendering should be performed as photorealistic as possible Photorealistic is something realistic seen through a realistic camera

34. Diego Colombo colombod@di.unipi.it Dead or Alive 4 (Xbox)

35. Diego Colombo colombod@di.unipi.it Cinematic.. Games move from one level to another through short movies Graphics definition should match as much as possible

36. Diego Colombo colombod@di.unipi.it DevilMayCry3(PS2) & 4(PS3) Game Short Movie

37. Diego Colombo colombod@di.unipi.it How To A good combination of –Low Poly –Textures –Reflection –Refraction –HW Acceleration –Normal Map

38. Diego Colombo colombod@di.unipi.it Ninja Gaiden XBox Game

39. Diego Colombo colombod@di.unipi.it Effects and sparkles (God of War) Games arise from imagination Putting supernatural in game enforce the performance Do it when it is necessary

40. Diego Colombo colombod@di.unipi.it Masses and AI: Colossal Games (Spartan total warrior) Noise is noise, not duplication!

41. Diego Colombo colombod@di.unipi.it Just a shopping list for game makers 3D authoring tool (Maya) 3D Painting tool (3DPaint, 3DPaintUV) Character Animation tool (MotionBuilder) Image editing tool (Photoshop) Game Engine Exporters
