Sin3D is a lightweight MonoGame extension library designed to reduce boilerplate and make creating 3D games feel as simple as working in 2D.

It provides clean, high-level abstractions for cameras, rendering, models, and collision detection — without hiding or replacing MonoGame’s core.

Camera3D class:

• Handles view and projection matrices.

Renderer3D class:

• Toggleable default BasicEffect lighting.
• Configurable directional BasicEffect lighting.
• Configurable fog.
• Single-line render calls.

Model3D class:

• Handles position.
• Handles rotation (quaternion-based).
• Handles scale.
• Handles World matrix.
• Texture mapping (including per-mesh texture-mapping for multi-meshed models).
• Collision detection with other models (including multi-mesh models).

• Bounding spheres
• Axis-aligned bounding boxes (AABB)
• Oriented bounding boxes (OBB)
• Optimized collision pipeline: Bounding Sphere → AABB → OBB

• Install MonoGame and add to your project.
• Install Sin3D and add to your project.
• Start coding! (sample projects can be found in the SampleProjects folder ready for you to build!)
