DEVLOG 2 - Consolidation of things learned
 
Well,
What’s new? Just a square? It might not seem like much, but yes. I spent all these hours rewriting the entire code from scratch so I could understand where I had the most doubts and therefore review some concepts.
 
Synchronization was and still is the most difficult concept to grasp; understanding how the semaphores and barriers are linked together wasn’t easy for me, and I must admit I still have some doubts about it, but certainly much less than before. Given the asynchronous nature of the graphics card, you can’t program operations that will be executed in order, unlike the CPU, and this is one of the graphics card’s strengths and weaknesses. You can parallelize many operations, but you have to be careful how they are linked together and synchronize them as correctly as possible.
 
My next step, I think, will be to use buffers to give more complex geometry to the shaders, primarily for drawing 3D geometry. I also think I still have to delve deeper and better understand things like semaphores, timeline semaphores, and barriers, which are topics I feel I haven’t internalized as well as others.
