I want to draw a circle using lwjgl (with OpenGL as underlying library) as a hello world program

...and the jvm just keep crashing

Fine.

Anything related to C++ is hard.

@skyblond do you have to calculate out a circle by hand? I havent used lwjgl

@freemo
If my memory is correct, drawing a circle in javafx or awt is really easy, even with manually calculating the coordinates.

In that video he use gpu shader to speed up large scale simulation and it looks cooooool
