RenderDoc is a free MIT licensed stand-alone graphics debugger that allows quick and easy single-frame capture and detailed introspection of any application using Vulkan, D3D11, OpenGL & OpenGL ES or D3D12 across Windows 7 - 10, Linux, or Android.
Flex Engine is my personal rendering engine which currently supports both Vulkan and OpenGL. It was started in February 2017 as a way for me to better understand how rendering engines work. You can find the entire source code on my GitHub github.com/ajweeks/FlexEngine Follow my progress on this project on my blog at ajweeks.wordpress.com/tag/flex-engine
