nektonic - A game engine (formerly SinGE)

Demersi

nektonic was largely inspired by ideas I had while developing WillowEngine and using other game engines and tools. Demersi was a game developed with nektonic and was the primary motivator of engine direction and development. Demersi may be downloaded on my website.

Compiling

Windows

Building on Windows requires Visual Studio 2017. Simply clone the repository, open SinGE.sln, and build all. Dependencies will be automatically downloaded and cached during the build process.

Linux

Linux guide coming soon (aka, once I test it). It does work, though.

Development Roadmap

I haven't made any major contributions to this in quite a while, since I'm busy with work and other projects. However, I still think about it a lot, and I'd like to write down some ideas for the (possibly distant) future.

Renderer

  • Move away from deferred rendering. It's been fun but very few of my projects have come close to justifying it and there's other things I want to try anyway.
  • Overhaul material system. I'd like to have something like Unreal's Material/Material-Instance concept, since that not only decreases loading time but also decreases artist workload.
  • Implement some nice effects like screen-space reflection, physically-based lens flare, real-time shadows (I got this close to finishing it for Demersi), and GPU-based particles.
  • Rewrite the lightmapper to support image-based lighting, more efficient sampling methods, multiple light sources, importance volumes, previewing (progressive lightmapping), and a more efficient storage/loading mechanism. This part of the engine is a good candidate for keeping as a seperate library, so I'd like to pursue that.
  • Make the rendering engine more generic, with some ideas I had for how that could be done without significant loss of performance.
  • Do even more research into physically based shading.

Engine: Short-term

  • Rebuild scene system. Think: Less Unity-style components and more Godot-style nodes. I've thought a lot more about how things are layed out and how I'd like them to be, and I think this is a really good approach moving forward. It better satisfies my goals of predictability and composability.
  • Prefabs! I've been putting this off for too long, mainly because I just want to do it right. This would include nesting and instancing.

Engine: Long-term

  • Rewrite physics integration on top of PhysX instead of Bullet. Bullet is perfectly fine in terms of features and performance, but it's a bit buggy and I really despise the API. It would be really cool to write my own physics engine, but that's a project for another day.
  • Implement audio system, potentially using steam-audio? I haven't explored this space very much, which is dumb because I think sound design is an absolutely crucial component of game design.
  • Implement animation system. This would include skeletal animation authored in a seperate program, as well as property animations authored in the editor(?).
  • Build a good resource manager. Somehow I always end up having a really crappy runtime resource manager, or none at all. Neither is particularily ideal, but this isn't exactly a priority either. Even if loading of resources isn't handled any more intelligently than it is now, I at least need a smarter way of organizing and storing resources and metadata on-disk.

Engine: Unknown-term

  • Build prototype editor and game GUI with Buoy or some other GUI library. Blender's great for hacking on top of, but it's not a very maintainable solution. I've gone without a decent GUI solution in my game projects for long enough, and I'd like to develop/find something I can stick with. This is a high priority, but it's not exactly something I think could be considered short-term.
  • Build BSP/voxel level prototyping tool. Even if none of the results are used in production, it's great to have something for whipping out ideas in a short amount of time. Unreal is the only real game engine I can think of that's come close to doing this right, but I think it can be done even better.
You can’t perform that action at this time.
