README 原文摘要

# 💻 Neo 3D Console (C#)

<img width="2070" height="1085" alt="Image" src="https://github.com/user-attachments/assets/06934758-90d4-4b63-9f40-8bb44ca2831e" />

A minimalist 3D engine written in C# that runs entirely inside the system console. This project was built from scratch without any external graphical libraries or modern graphics APIs (like OpenGL or DirectX). Everything—from custom vector mathematics to ray casting/tracing and the TCP network stack—is computed entirely on the CPU.

This project was designed for educational and demonstration purposes for a [YouTube video](https://youtu.be/vhYE882B9dE).

## 🚀 Key Features

1. **CPU Raycasting / Raytracing**:
    * Renders polygonal meshes (`.obj` format) and geometric spheres.
    * Intersection optimization using Bounding Sphere checks before performing detailed triangle intersection calculations.
2. **Dynamic Lighting and Shadows**:
    * Light intensity attenuation based on distance.
    * Lambertian diffuse shading using surface normals.
    * Real-time shadow rendering via Shadow Rays cast from intersection points back to light sources.
3. **Multi-threaded Rendering**:
    * Leverages `Parallel.For` to distribute pixel rendering calculations across all available CPU cores.
4. **Optimized Console Output**:
    * Map light intensity to a character gradient string (`" .:!/r(l1Z4H9W8$@"`) to simulate shading.
    * Frame buffering with grouped-color output to minimize slow, native OS terminal print API calls.
5. **Custom 3D Mathematics**:
    * Custom implementations of `Vector3`, `Vector2`, `Ray`, and rotation matrices (Euler rotations around X, Y, and Z axes).
    * Manual implementation of the Möller–Trumbore ray-triangle intersection algorithm.
6. **Low-level Window Input**:
    * Asynchronous, non-blocking keyboard polling using the Win32 API (`GetAsyncKeyState`), ensuring key presses are detected only when the console window is active.
7. **Custom Network Multiplayer**:
    * Client-server TCP netwo
