Spartan is a research-focused game engine designed for real-time solutions, providing a dynamic experience. Not intended for game development yet, it serves as a valuable study resource due to its clean, modern, and high-quality architecture.

• Shadows with penumbra and colored translucency (Cascaded and omnidirectional shadow mapping with Vogel filtering)
• SSGI (Screen space global illumination, an extension of SSAO)
• SSR (Screen space reflections)
• SSS (Screen space shadows)
• TAA (Temporal anti-aliasing)
• Physically based camera (Aperture, Shutter Speed, ISO)
• Depth of field (controlled by the aperture of the camera)

• Entity-component system
• Event system
• Mouse & keyboard input as well as controller support (tested with a PS5 controller)
• Debug rendering (Transform gizmo, scene grid, bounding boxes, colliders, raycasts, g-buffer visualization etc)
• Thread pool
• Engine rendered platform agnostic editor
• Profiling (CPU & GPU)
• Support for XML files

Roadmap

Short-term

• Fix the remaining startup crash for Vulkan.
• Switch to bindless.
• Outperform D3D11.
• Deprecate D3D11.
• Continue work on D3D12 (on going and non blocking since Vulkan is there).
• Create a startup/default world which is closer to playable to a demo.

Long-term

• Skeletal Animation.
• Atmospheric Scattering.
• Eye Adaptation.
• Subsurface scattering.
• Ray traced reflections.
• Ray traced shadows.
• Dynamic resolution scaling.
• Export on Windows.
• UI components.
• Improve editor looks.
• Scripting.
• Linux port.
