Crossplatform 3d engine. (work in progress)
Tempest is an open-source, simple, cross-platform graphics engine written in modern C++14.
Main idea behind this engine is to provide a low-level GPU-programming concepts, like Ubo, Vbo, Ssbo, in convenient C++ packaging, with RAII, types and templates.
- Multiplatform (Windows, Linux, 32bit and 64bit)
- Multibackend (Vulkan 1.0, DirectX12)
- Multithreaded command buffers and thread safety
- Build-in 2d graphics support
- Build-in UI library
