A real-time 3D scene composition tool in C++ featuring a hierarchical scene graph, command-based undo/redo, and automated asset pipelining via tinyobjloader and stb_image.

Build Instructions

1. Ensure CMake (3.15+) and a C++ compiler are installed.
2. mkdir build && cd build
3. cmake ..
4. make
5. ./SceneEditor

Controls

• [W,A,S,D,Shift,Space]: Move Camera
• [Right Click + Mouse]: Look Around
• [Left Click]: Select Object (In World Outliner)
• [Ctrl+Z / Ctrl+Y]: Undo/Redo

Core Architecture

• Scene Graph: Implements a tree-based parent-child relationship system for complex object assemblies.
• Command Pattern: Encapsulates all editor actions (Transform, Texture, Create, Delete) to provide a robust, non-destructive history stack.
• Asset Pipeline: Utilizes tinyobjloader for hierarchical mesh parsing and stb_image for automated MTL material mapping and texture caching.

Test Cases

• Test Case 1: Cube Stack (Physics/Stacking layout).
• Test Case 2: Procedural Table Assembly (Parenting & Scale).
• Test Case 3: Sponza Atrium (High-poly environment & Automated Materials).
