I want to draw a circle in OpenGL. I have looked for examples of how to do this, but the only ones I can find use deprecated functions such as glBegin(), glEnd() and glVertex().

Can somebody provide an example of how this can be done using modern OpenGL?

Thanks.

Really ?

There are too many possibilities, as points, lines, line strips, triangles, triangle fans. In principle you fill a vertex array and eventually an index buffer with vertices describing a circle and unleash a draw call on it ...

Points on a circle are:

x = radius*cos(angle); y = radius*sin(angle)

Or vice versa. The more points, the rounder ?

Since you didn't specify what you want exactly, I'll mention the fairly obvious solution of using a texture with a circle on it ? If neither this nor the answer above give you what you need, maybe you can clarify your question a little.

@calioranged, I wrote my code in Eclipse: Circle_GlfwLwjgl3OpenGL31Java.zip
