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
Yeah, I have to manually calculate each point on the circle using a for loop.
I recently watch a youtube video about simulate the behaviour of ant colony. He used OpenGL with cpp and I want to implement my own version. But it seems like OpenGL and cpp things are far beyond my control XD

@skyblond opengl is totally doable, you will just be coding at the vector level, so rather tedious. Thats what you get with low-level really.

If you want something easy but powerful consider scene-graph type engines on top of opengl, they are way more intuitive.
