Hi

Thanks for sharing the Galaxy Renderer, it´s really nice.
I have adapted it as a background to a game I'm writing and I found that it has problems in iOS. The issue is that sometimes the point size is negative and iOS then renders it wrong.

I have added:

 gl_PointSize=max(gl_PointSize,0.0);

at the end of the vertex shader and now it works Ok. Don't know if there is a better way to correct it. Hope it helps.

I attach a screen shot of my game

Star.cpp refers to Star.hpp, which does not seem to be in the repo

Also there are references to MathHelper.hpp in Star.cpp, which also doesn't exist.

Well, I found this trying to create a Makefile for linux, so it's possible that Star.cpp is not used at all. But now I'm at an impasse because:

c++ -std=c++17 -Iinclude -I/usr/include/SDL2 -c -o Galaxy.o Galaxy.cpp
Galaxy.cpp:7:21: fatal error: execution: No such file or directory

my C++ compiler doesn't support

#include <execution>

Along the way, I also noticed 3 instances of

#include <gl/blah.h>

That doesn't work on linux because it needs to be uppercase GL.

#include <GL/blah.h>

I really really don't understand why you don't explain how to run the program in the description?
