Maybe. The pixel ownership test (whether the fragment lies within the window) and the scissor test are performed prior to the fragment shader...

OpenGL is not software You don't download and install OpenGL. Instead, OpenGL is provided as a component of your graphics card's drivers, so you...

Ah thank you very much! A small test shows that this could work. But ok, what will happen then is basically the following, right? -For every point,...

Additive blending (i.e. glBlendFunc(GL_ONE,GL_ONE)) will sum colours. Depending upon the number of points which may fall within a pixel, you may need...

Thank you for your reply, in the next days I will try to search for that function and post the result!

A SwapInterval of 1 is the usual default for most window system interface layers that OpenGL is stacked on top of (examples: WGL, GLX, AGL, EGL). ...

Note that this is far from straightforward. It isn't generally possible to define an offset curve as another curve of the same type and degree. E.g....

I doubt that there is any resource on "how to build a 2d race track". There are so many possible ways to achieve what you want and the best way is...

we can not help if u not show ur problem

Think I have found the solution: This line should be removed: glEnable(GL_CULL_FACE); Thank you.

Support for multi-threading can vary by platform, but all of the most common platforms (Windows, MacOS X, Linux) support multi-threading. However,...

use a library for that: https://www.freetype.org/freetype2/docs/index.html https://learnopengl.com/In-Practice/Text-Rendering

Thanks for the reply. :) So, rather than rendering each character as a texture, is there any easy way to render fonts in GLFW?

The utility functions (text, geometric solids) will probably work so long as glutInit() has been called and you don't have a core profile context. ...

You asked for a way to discard fragments "if it greater than a certain value (specifically 0.5)". The only way to do that is with fragment shader...

You could bench both alpha test (compatibility profile) and discard, though I'd expect similar performance from both. Depending on your use case,...

So tell us, what was the problem?

Thanks for your reply ProgrammerX. I have solved the problem. :)
