Description

The goal of assignment 3 and 4 is to reimplement the shooting game in 3D. In assignment 3, you focus on 3D wire-frame rendering and 3D camera control. In this assignment, you don’t have to implement lighting, shading, and texture mapping; the three categories will not be counted as additional scores.

Requirements

(Important)
 Implement the same game in assignment 3-1 and 3-2, satisfying the requirements described in this document.
 In assignment 3-1, use the fixed pipeline of OpenGL, i.e., use traditional OpenGL APIs.
 In assignment 3-2, you cannot use the fixed pipeline of OpenGL. For example, glBegin() or glEnd() cannot be used. Design your own rendering pipeline by implementing shaders using GLSL.
 In assignment 3-2, you can use GLM (a header only library). (https://glm.g-truc.net/0.9.9/index.html)  You have to submit a report for each of assignment 3-1 and 3-2.

• Characters
◦ Find or make 3D spaceship models to represent player and enemies.
(Keep in mind) in assignment 4, you’ll implement texture mapping. Therefore, you’ll want to use UV-mapped meshes in this assignment. Check if the meshes are UV-mapped before using them in your project.
You might just want to use a bunch of cuboids or capsules to design a character. You can create such simple geometric primitives manually with code, or design them in other tools like Blender (https://www.blender.org/) and import/export them by parts.
In this assignment, you don’t need to consider hierarchical structure of the character and the animation loop.
• Background
◦ The ground is expressed in a grid. (Refer to Figure 1)
◦ The celestial bodies (star, planet, satellite) in the planetary system are expressed as spheres.
The hierarchical structure and animation loop of the planetary system are applied in the same way as in assignment 2.
• System
◦ Bullets and items are represented as simple 3D objects.
◦ A certain area of the ground is set as the boundary of the game. (Refer to fig. 2)

Figure 2. Example of boundary setting

• Viewing
◦ Implement two viewing modes. (Refer to fig. 1)
3rd-person view: the camera is somewhere behind the player (Default)
1st-person view: the camera is in front of the player ◦ You can change viewing mode by pressing ‘v’.
• Rendering
◦ Implement two rendering modes.
Mode 1: wire-frame without hidden line removal (Default)
Mode 2: wire-frame with hidden line removal ◦ You can change rendering mode by pressing ‘r’.

Misc.
• You can either implement yourself or use library when loading mesh models.
• Other unspecified requirements are the same as assignment 2.
• If you want to implement other views, provide the views in the requirement and add additional modes for custom views.
• You are free to implement any details that are not specified and record them in the report.
• If you implement additional functions unspecified in this document, you can get extra points, up to 10% of the full score.
◦ This should be stated in the report.
