Soft 3D

Soft 3D Engine is a lightweight, purely software-driven 3D rendering engine built from scratch in C++. 

The engine performs all rasterization, matrix transformations, and physics-based logic entirely on the CPU, using SFML solely as a multimedia library for window context management, input handling, and displaying the final pixel framebuffer.

Key Features:

Pure CPU Pipeline: Custom triangle drawing and rasterization executed entirely on the CPU.

Performance Tuning (Tile Size): Includes a "Tile Size" slider in the settings. Note: Lowering this value increases the CPU workload exponentially (Default standard is 512).

Multiple Shading Modes: Real-time rendering style toggle (Wireframe, Solid, etc.) using 1-4 keys.

UI-Free Screenshots: Dedicated capture system saving pure 3D canvas outputs to .png, bypassing Dear ImGui overlay.

Controls & Shortcuts:

Object Manipulation Pipeline:

  1. Select Action: Press S (Scale), M (Move), or R (Rotate).

  2. Select Axis: Press X, Y, or Z to lock the modification to a coordinate.

  3. Adjust Value: Scroll the Mouse Wheel up or down.

  4. Apply Changes: Click Left Mouse Button (LMB) to confirm.

Render & Camera Controls:

  - Keys 1, 2, 3, 4: Cycle through rendering modes on the fly.

  - LAlt + Mouse Wheel: Dynamically adjust the Camera's Field of View (FOV).

System Requirements:

 - Windows OS (x64)
