Graphics Programming Assignment - Spacecraft Scene (Received 93% Grade)

How to Run

To compile:

$ javac Spacecraft.java

To run:

$ java Spacecraft

Project Structure

The project is organized into the following packages:

• camera: Camera and input handling
• gmaths: Mathematical utilities
• graphics: Core graphics components
• primitives: Basic 3D shapes
• scene: Main scene and object implementations
• scenegraph: Scene graph hierarchy implementation
• utils: Utility classes

Declaration

All work in the scene, utils package is my own work. I have also modified several files in the gmaths and camera packages and all the shaders. Find the sources of the textures in readme.txt in assets/textures.

Implemented Features

1. Room

• Textured walls, floor, and ceiling with multiple texture mapping techniques:
  • Normal mapping for surface detail
  • Specular mapping for realistic reflections
  • Height/Parallax mapping for depth effects
• Back wall features dynamic specular-mapped text
• Right wall demonstrates advanced repeating texture with normal and height mapping
• Floor uses multi-layered texturing for path visualization
• Ceiling implements opacity mapping for sci-fi grid effect

2. Window and Space View

• Custom fragment shader implementation for window frame effects
• Advanced depth handling for window transparency
• Multi-texture blending for frame materials
• Normal mapping on metallic frame for realistic lighting

3. Advanced Shader Features

• Implemented multiple mapping techniques:
  • Normal mapping for surface detail enhancement
  • Parallax/Height mapping for depth perception
  • Specular mapping for material reflection properties
  • Opacity mapping for transparency effects
• Custom shader implementations:
  • Multi-light shader supporting directional, point, and spotlight sources
  • Window shader with frame rendering and transparency
  • Skybox shader with rotation effects
  • Material shader with multiple texture coordinates

4. Material System

• PBR-inspired material system with:
  • Diffuse texturing
  • Specular reflection mapping
  • Normal mapping for surface detail
  • Height mapping for parallax effects
  • Opacity mapping for transparency
• Custom material parameters for:
  • Ambient light response
  • Diffuse light scattering
  • Specular highlights
  • Surface roughness
    • Spins around the y axis

Controls

Camera:

• Arrow keys: Move camera position
• A/Z: Move forward/backward

• Toggle Robot 2: Start/stop Robot 2's movement
• Toggle Main Light: Turn on/off main scene light
• Toggle Spotlight: Turn on/off Robot 2's spotlight
• Light intensity sliders: Adjust brightness of lights
