Simple3D

A modern, cross-platform 3D modeling and visualization application built with C++23, Qt and OpenGL 4.6.following a modular and incremental development approach

Current Features

Core Features

• Modern OpenGL-based rendering (OpenGL 4.6)
• Interactive 3D viewport with grid and coordinate axes
• Camera controls:
  • Orbit camera with mouse drag
  • Zoom with mouse wheel
  • Auto-clamped vertical rotation to prevent gimbal lock
  • Configurable camera distance limits (2-50 units)

User Interface

• Clean, modern Qt-based interface
• Dockable panels:
  • Properties panel with transform controls
    • Position (X, Y, Z)
    • Rotation (X, Y, Z)
    • Scale (X, Y, Z)
  • Layers panel
• Standard application menus:
  • File (New, Open, Save)
  • Edit (Undo, Redo)
  • View (Reset View)

Technical Features

• Modern C++23 codebase
• Shader-based rendering pipeline
• Vertex buffer objects (VBO) for efficient geometry rendering
• Multi-sample anti-aliasing (MSAA) support
• High DPI display support
