Console3DGame is a real-time 3D engine built entirely for the Windows Command Prompt using C++ and Win32 API. Unlike traditional game engines, this project renders fully 3D environments using only text characters, achieving smooth movement, dynamic lighting, and textured floors—all within the constraints of a terminal.
✔ True 3D Rendering – Uses raycasting or rasterization to project a 3D world onto a 2D console grid.
✔ Advanced Movement – WASD controls, mouse look, and collision detection.
✔ Dynamic Lighting – Simulates light falloff and shadows using ASCII/Unicode gradients.
✔ Win32 Optimization – Leverages low-level console buffering (SetConsoleActiveScreenBuffer) for flicker-free animation.
✔ No External Libraries – Pure C++ and Win32 API for maximum performance and minimal dependencies.
The engine tricks the console into behaving like a GPU by:
- Mapping 3D Space to Characters: Each "pixel" is a carefully chosen ASCII/Unicode glyph (e.g.,
▓,▒, - Double Buffering: Swaps between two console buffers to eliminate flicker during rendering.
- Raycasting: Projects rays from the player’s view to determine distance and wall height (similar to Wolfenstein 3D).
- Procedural Generation: Levels can be dynamically generated or loaded from data.
This engine transforms ordinary terminal characters into a 3D world using:
-
Mathematical Projection
- Converts 3D coordinates to 2D console cells with depth preservation
- Dynamic character shading (█ ▓ ▒ ░) based on distance and lighting
-
Cinematic Effects
- Depth Fog: Distant objects fade into background
- Dynamic Shadows: Real-time light occlusion
- Smooth Animation: 60 FPS frame interpolation
