ZeroZero is a 3D game engine based on Vulkan 1.4 and Jolt 5.x made in Modern C++ for learning purpose.
Released under the MIT license.
Features
Some of the features actually implemented or under construction :
- Vulkan based forward rendering system with optional depth pre-pass and multisampling.
- Scene tree with classic, object-oriented node system (inspired by Godot, including the signal system).
- Physic system based on Jolt Physics.
- PBR materials & shader.
- Cel-shading shader
- Shader-based materials.
- Frustum culling.
- In-game debug
- Blender add-on
- JPEG/PNG and HDRi skybox.
- Directional lights, omni (point) lights and spotlights.
- Image based lighting for HDRi skybox.
- Cascaded shadow maps for directional lights.
- Cubemap shadow maps for omni lights.
- JSON scene files.
- glTF support.
- ZRes binary file format for better loading time and decreased VRAM usage.
- UI framework
- Animations
- Additional post-processing shaders : HDR tone mapping, edges drawing, FXAA, FOV, ...
