Features

• Voxel-based Rendering: Create and render 3D voxel models using both CPU and GPU-based visualizers.
• Marching Cubes Algorithm: Visualize voxel data with smooth surfaces using the Marching Cubes technique.
• Simplex Noise: Generate procedurally textured terrains and grids with Simplex Noise.
• Custom Shaders: Fine-tune visual appearances with a variety of shaders, including terrain, water, wireframe, and skybox effects.
• Interactive Voxel Painting: Paint directly onto voxel objects using a variety of materials and textures.
• High-Quality Materials and Textures: Supports a wide range of materials, from basic terrain to sci-fi inspired designs.
• Custom Prefabs and Scenes: Includes pre-built scenes and prefabs for rapid development and experimentation.
• Visualizer Modules: Modular visualizer scripts that offer flexibility in rendering voxel data.

Project Structure

The project is organized into the following key directories:

• Assets/Materials: Contains various materials for voxel rendering, including specific textures for terrains, water, and objects.
• Assets/Prefabs: Contains pre-configured prefabs such as ClickableMesh.
• Assets/Scenes: Includes two primary scenes, MainVisualizersScene for rendering visualizations and PrototypeLevelScene for prototyping voxel structures.
• Assets/Textures: A wide variety of textures for water, stone, tiles, and sci-fi elements to enhance the voxel models.
• Assets/VoxelPainter: The core of the project, with subdirectories for generation and rendering, housing essential scripts and shaders.

How to Use

1. Clone the Repository:

   git clone https://github.com/yourusername/VoxelPainter.git

2. Open in Unity: Open the project in Unity 2022.3.15f1 (other versions might work fine as well) + URP

3. Explore the Scenes:

   • Open MainVisualizersScene to see the voxel painting and visualization in action.
   • Use PrototypeLevelScene to experiment with voxel structures and designs.

4. Customize Your Voxel World:

   • Modify the materials, textures, and shaders in the Assets/Materials and Assets/Textures folders to create your own visual style.
   • Play with the visualizer scripts under Assets/VoxelPainter/Rendering to change the rendering techniques.

Technologies Used

• Unity Universal Render Pipeline (URP): For high-performance, flexible rendering.
• Marching Cubes Algorithm: For creating smooth voxel surfaces.
• Simplex Noise: For procedurally generating complex terrains.
• Custom Shader Graphs: Extensive use of Unity Shader Graph for custom visual effects.
