Cross-platform game engine with Vulkan backend
Flex Engine is a personal game engine I began work on in February 2017. I use it as a playground for learning about real-time techniques. I try to keep master reasonably stable, and therefore update it infrequently. See development for the latest changes.
Basic implementation of Cascaded Shadow Mapping
Two million particles updated and rendered entirely on the GPU, utilizing the compute stage
Profiler overlay showing a breakdown the CPU-time of a single frame
Some of the editor windows
Screen-Space Ambient Occlusion (SSAO)
GBuffer (top-left to bottom-right): position, albedo, normal, final image, depth, metallic, AO, roughness

Flex Engine uses the following open-source libraries: - Bullet - Collision detection & rigid body simulation - FreeType - Font loading - glfw - Window creation, input handling - glm - Math operations - ImGui - User interface - OpenAL - Audio loading and playback - stb - Image loading - cgltf - Mesh loading - volk - Vulkan meta-loader
Flex engine is released under The MIT License. See license.md for details.
