# KVF
|
||||
|
||||
KVF (kbz_8 vulkan framework) is a lightweight single-header Vulkan framework written in C99 to simplify the creation of Vulkan applications.
|
||||
It is designed to be a drop in framework inside any existing Vulkan renderer as it does not use any custom types of structs (except for the graphics pipeline builder).
|
||||
|
||||
Here's a simple C example of a hello world triangle using KVF and SDL2 :
|
||||
```C
|
||||
#include <SDL2/SDL.h>
|
||||
#include <SDL2/SDL_timer.h>
