stdlib...shaders

This is a single-file implementation of shaders using only the stdlib. Shaders where initially writen in GLSL Check it out, but as you can see, you don't need GLSL

Dependencies

• ffmpeg
• any cpp compiler for C++20 or above

How to generate the .mp4

1. Compile the source file with any C++ compiler

   c++ -O3 -std=c++20 main.cpp
   # or
   ./build.sh

2. Run output file

   ./a.out

3. Generate the video There are multiple ways to generate the video, explore ffmpeg, its a great tool

   cd frames
   ffmpeg -framerate 30 -i out%03d.ppm -c:v libx264 -pix_fmt yuv420p temp.mp4
   ffmpeg -i temp.mp4 -vf reverse reversed.mp4
   ffmpeg -i temp.mp4 -i reversed.mp4 -filter_complex "[0:v][1:v]concat=n=2:v=1[out]" -map "[out]" seamless_loop.mp4
