2. Outline • Introduction • Background • Method • Tutorial Introduction • Examples • Results Analysis • References

3. Introduction • The game and entertainment industry plays an enormous role within the development and extensive usage of new technologies • A convergence between the fields of computer graphics and computer vision has been observed • This convergence has been motivated by the idea to create photorealistic visualizations of real world scenes in a computer

4. Introduction (cont.) • 3D Gamestudio is a 3D computer game development system which allows users to create their own 3D applications and publish them royalty-free • It comes complete with a model editor, a world editor, and a script editor. • It also has an expansive texture collection, template scripts, and more, enough to create a simple 3D game

5. Background(1) • Some issues of 3D video : • Recent technological make it seam feasible to lift the medium video onto a novel, an immersive level. • Data storage • Transmission technology • Presence of specialized graphics hardware • The algorithmic core of 3D video is formed by: • Methods for the reconstruction of shape • Appearance models of real-world scenes from video data • Algorithms for rendering them in real time

6. Background (2) • Some issues of 3D video game design: • There is a recent increase in the number of game environments or engines that allow users to customize their gaming experiences by building and expanding game behavior • Real-time visualization of 3D data is already well established and also commercially successful in the entertainment industry, namely in the market of 3D video games • The number and complexity of visualization tools for analyzing and exploring data has increased dramatically

7. Background (3) • 3D Game Engines are low-cost, networking support, collision detection, support for high frame rates per second, and entry level hardware requirement • These game engines include not only visualization functionality, but also offer physics, sound, network, artificial intelligence and graphical user interfaces to handle user in- and output. • These engines can be extended to build more serious applications at very little costs

8. Method • The purpose of this project is to introduce you to 3D game studio by helping you create a small model. • 3D game studio is an excellent tool to quickly prototype and develop 3D graphics applications • No programming experience is required. • In this experiment we want to evaluate the usefulness of this tool to prototype and develop 3D graphics applications as curricula aids in their classrooms with 3D game studio.

9. Tutorial Introduction 1. Download and install the 3D Game Studio by checking this link:http://download.conitec.net/gsdemo.exe2. Look at the tutorial for 3D game development. 3. Follow the tutorial, and run the simulation by yourself.4. Print the Questionnaire and give the choice for each item about the experiment process.

10. An example: Create Static Flower Model • Open the Model Editor environment. • Click button • Click “All Programs” • Click “3D Game Studio” • Create a new model • Press File on the menu • Then click “New” • Or press “New” icon on the tool bar • Create a simple 3D object • Click “Object” on the menu • Click “Primitive” • click “Cylinders” • Select “Six-sided” • You will see the new six-sided cylinder in 3 dimensions • You drag the cylinder by mouse in different dimensions, and observe the motion

11. Load an existed model • Load an existed model • Click “Object” on the menu • Click “Prefab” • Choosedirectory “Plants” • Choose “PETAL.WMP” • Click “OK”

12. Modify the Model • Resize “Petal” • Click the petal to select it (notice it will turn to red) • Click “Mode” on the menu • Select “Object Scale” • Move your mouse to resize the Petal • Do the same to resize the Cylinder • Move “Petal” to the right place • Click the petal to select it • Click “Mode” on the menu • Select “Object Move” • Use your mouse to drag the Petal to the right place • Rotate “Petal” to the right place • Click the petal to select it • Click “Mode” on the menu • Select “Object Rotate” • Rotate the Petal in the right dimension • Different views will result in different rotation

13. Color the Model • Click “Texture” on the menu • Click “Texture Manager” • Choose “Add WAD” • Choose “standard.wad” then Open • Click “OK” • Click “Texture” on the left workspace • Click “standard.wad” • Choose “Add WAD” • Drag the slider bar to find the greenplain texture • Click the one you choose • Select Cylinder • Notice it turns to red • Click the greenplain on the Texture Workspace • Notice the “Object” in Texture Workspace turns to green

14. Run the Model • Press Build button • Click “OK” • Press Compile button • Click “OK” • You see the static 3D model • Use your Keyboard up and down to adjust the views • You can add more petals to this model, and to create a flower finally

16. Another Example: Create A Motion Model • Open the Model Editor environment. • Click button • Click “All Programs” • Click “3D Game Studio” • Click “Model Editor” • ChooseGXL Objectwhen run at the first time • Choose both “Gxl2DX8A.dll” from 2-d and 3-d • Open a .wmp file created by GameStudio • Click “File” • Click “Open…” • Select file type “A5 Level File” • Select the file have been created by GameStudio • Save model as a MDL file • Click “Save” and then choose file type “MDL7” • Click “OK”

17. Create a new frame • Click button • Add a new frame • Click “Edit” • Click “Add Frame…” • Set property of new frame • Select “use current frame” • Click “OK” • Move the object to a new position • Select the part tended to be moved • This part will become into red • Click button • Press left button and move the object • Click button to save this new frame • Play the motion • Click button to play the motion

18. Results Analysis Fig. 1 The task was easy for me to learn and use

19. Fig. 2 It was easy to get started

20. Fig. 3 It was difficult to remember where some of the tools and commands were located

21. Fig. 4 This task would be easy to complete by folks who don’t know much about computers

22. Fig. 5 This system would be fun for building simulations

23. Fig. 6 I have a good understanding of how to use this system to complete the task

24. Fig. 7 Turning my ideas into working simulations was complicated

25. Fig. 8 How many steps would this take to create a new object

26. Fig. 9 Rule ordering was confusing Fig. 10 It was hard to recover from errors Fig. 11 I was able to use this system to turn my ideas into working simulations Fig. 12 I found the creation of rules for object behaviors confusing

27. Fig. 13 The rules I created for objects’ behaviors were simple and natural Fig. 14 I am enthusiastic about creating new simulations
