![]() However, at some point this functionality has been deprecated in favour of GLM accepting angles in radians. Therefore the developers of GLM decided that they would also accept angles in degrees by default. Legacy OpenGL used to accept angles in degrees. We need cstdio and cstdlib for fprintf() and exit(). In this section we will create the c++ file main.cpp, which contains the main() entry point. ![]() ![]() I also plan on using the sparse buffers in my voxel-engine. Yes, I said I wanted to avoid extensions, however, those three are part of AZDO (approaching zero driver overhead) OpenGL, so I want to be able to explain their use as well. Furthermore, because you put glad.c and glad.h in the same folder, you should change glad.c to replace #include with #include "glad.h". The package also contains a file khrplatform.h, which you don’t need if you remove the line #include from glad.h. Click generate download the zip-file and unpack glad.h and glad.c into a folder named glad in your source directory. Glad is a loader generator, so head over there and choose API: gl version 4.5, Profile: core, Extensions: GL_ARB_bindless_texture, GL_ARB_sparse_buffer, GL_ARB_sparse_texture, Options: uncheck ‘generate a loader’. In my previous post, I decided that I’m going to use GLM, SDL2 and Glad for that. In this post I’ll describe how to set up an OpenGL 4.5 context.
