Simple Computer Graphic Project - Geunyeong Kim

video.mov

This project is a simple 3D renderer written in C++. It supports wireframe rendering, rasterization, and basic ray tracing of 3D models.

Features

• Wireframe Rendering: Draws 3D models as wireframes.
• Rasterization: Renders filled triangles using rasterization techniques.
• Ray Tracing: Implements basic ray tracing with lighting and shadows.
• Camera Controls: Move and rotate the camera using keyboard inputs.
• Lighting Controls: Adjust the position of the light source.
• Model Loading: Loads 3D models from .obj files.

Dependencies

• SDL2: Used for window management and rendering.
• GLM: OpenGL Mathematics library for vector and matrix operations.

How to Use

Compile the code with a C++ compiler and ensure all dependencies are properly linked.

Controls

• Camera Movement:

  • LEFT / RIGHT arrows: Move camera left/right.
  • UP / DOWN arrows: Move camera up/down.
  • 4 / 5: Move camera forward/backward.

• Camera Rotation:

  • W / S: Rotate camera around the X-axis.
  • A / D: Rotate camera around the Y-axis.

• Orientation Adjustment:

  • T / G: Adjust camera orientation around the X-axis.
  • F / H: Adjust camera orientation around the Y-axis.

• Light Movement:

  • Z / X: Move light along the X-axis.
  • C / V: Move light along the Y-axis.
  • B / N: Move light along the Z-axis.

• Rendering Modes:

  • 1: Wireframe rendering.
  • 2: Rasterization rendering.
  • 3: Ray tracing rendering.

• Miscellaneous:

  • L: Reset camera to look at the origin.
  • O: Toggle automatic orbit rotation.
  • Mouse Click: Save the current frame as output.ppm and output.bmp.
