An experment in learning voxel rendering. Still very much a work in progress and mostly a learning endevor.

Language and Librarys

Written in C# (VC2019 .net 4.6.2), using UrhoSharp https://docs.microsoft.com/en-us/xamarin/graphics-games/urhosharp/introduction.

Code should be crossplatform but it has not been tested.

All dependencies are in Nuget.

Projects

• GridWorld is the main library that stores the voxel world
• GWT Test harnes and dynamic loading/unloading code

Features

• 64 bit voxel indexing giving a world space of just under 2000 square lightyears if 1 unit = 1 meter
• Sliding origin to prevent floating point errors
• Supports static worlds or procedural generation (basic perlin for now)
• 16 bit dynamic block type indexes (only index the blocks types and shapes used)
• Multiple shapes including ramps
• Background threaded geometry generation/loading/unloading
• Near/Far geometry load/unload, stale node cleanup

ToDo

• World Database
• Dynamic Cluster Loading
• 3D Cluster indexes
• Editing
• Strucutres
• Edit Layers
• Network Transmission
• Better Collisions
• Client Cleanup
• Vertex Shaders for fluids
• Mobs
• Triggers
• Block Sub Meshes
• More block types (Thin Verticals, Cutoff Corners, etc...)
• Fancy Procedural Generation
