Some progress in #C++ and #OpenGL! I made a custom Material class that lets me assign textures and control how objects react to light. Also, I've spent four hours integrating ImGUI, just for the sake of that silly window at the corner... yeah, sounds like me... #programming #gamedev #indiegamedev - ThreadSky

Hi! Out of curiosity, could you help me by explaining what took you 4 hours to integrate the lib? Had you seen https://github.com/ocornut/imgui/wiki/Getting-Started ? genuinely interested, regardless of if you think it was due to something unclear or due to a mistake of yours, as my job is to keep facilitating this process.

Oh, hi!🙂 Integrating the library took me this much time mostly because of my lack of experience with cmake and library linking in general. I was just making tiny noob mistakes here and there. I guess I would make those mistakes regardless of the library I was trying to link

Were your linking problems related to imgui itself or to some support windowing or graphics library eg glfw sdl vulkan?
I’m very interested in those steps, i know they can be confusing for less experienced programmers.

It was mostly just me being dumb and struggling with add_library and target_link_libraries. The actual problem wasn't with imgui itself but just me figuring out how CMake works. Thanks for taking the time to ask, though! Didn't expect you to notice my post, lol

This looks awesome! how are you rendering the grid?

justcore.bsky.social•139 days ago

The grid itself is static, so if I flew far enough, I’d eventually see its edges. Fortunately, this can be easily solved by moving the grid along with the camera - but only in fixed steps equal to the grid cell size. This way, the grid always follows you seamlessly, making the edges invisible

i see! that's clever, thank you for the explanation!

Thanks! :)
For the grid, I generated vertex pairs along the edges rather than at every intersection. This way, I only needed vertices for the lines themselves, not each crossing point.
Then, I simply rendered them using glDrawArrays in GL_LINES mode. This drawing below illustrates the approach
