Playing with shaders - Part 1

Since I became a father of two twins, two months ago, I haven’t been able to do much coding at all. Any opportunity I get I have to make sure I do something really small since my work time gets very fragmented.

So I started a c++ project, open a window with an openGL context, and started playing with some really basic shader code. As I said, I didn’t get very far before I had to abort. But it’s something.

Just wanted to save the links to some pages that helped me setting up GLFW on windows in Visual Studio 1013.

#version 420 core

out vec4 color;
void main() {
float x = mod(gl_FragCoord.x, 100.0) / 100.0;
float y = mod(gl_FragCoord.y, 100.0) / 100.0;
color = vec4(x,y,1.0,1.0); }
