Csharp-3D-Viewer

A lightweight 3D model viewer built with C#, WinForms, and OpenTK (OpenGL). This application allows users to load, visualize, and interact with 3D models.

🚀 Features

• Multi-Format Support: Load .obj, .fbx, and .stl files seamlessly.

• Real-time Rendering: Powered by OpenGL (OpenTK) for smooth performance.

• Interactive Camera:

  -Rotation: Left-click and drag.

  -Panning: Right-click and drag.

  -Zooming: Mouse wheel support.

• Dynamic Sensitivity: Adjustable control sensitivity (zoom and pan) via a built-in trackbar for precision or fast movement.

• Texture Mapping: Apply image textures (.jpg, .png, .bmp) to your 3D models.

• Lighting System: Built-in ambient and diffuse lighting to enhance model depth.

🛠 Tech Stack

• Language: C#

• Framework: .NET Framework 4.8.1

• Graphics API: OpenGL via OpenTK

• Model Loading: AssimpNet

📸 Screenshots

• Loading model and texture, than Zooming/Panning/Rotation.

• There are some screenshots for 3D models in the "Examples" folder.
