A minor fix.
As you can see, contrary to the last devlog, the triangle is a bit taller! Why? Turns out, I’ve been using the same aspect ratio for the scene view as I was for the rest of the UI. Rookie mistake, innit? Either way, to fix it I just expanded my descriptor pool, created additional descriptor sets dedicated to the scene view, created new uniform buffers for those descriptor sets and bound the descriptor sets when binding the Scene pipeline. A simple fix, not gonna lie. Next up, ray tracing! yay…

Today’s a boring one.
I just improved the XML parser a bit, which did take WAY longer than I wanted it to take.
Oh well.

This was rather long, and I hated every second of it. Eh, I guess you learn through pain. The result is underwhelming nonetheless. What I’ve done is I made a very basic XML data parser using pugixml. Sorting and figuring the data out was a real pain. To be fair, I’m still unsure whether it works. Hopefully it does. I hope the next devlog will show the data being implemented.

Had to install NSight for this one. I added Uniform buffers, descriptor sets, etc. This allows me to translate, rotate both the geometry and the camera! Now that’s fun. It really is not. Either way, this should allow me to make a GUI, at last.

Now it’s not just a triangle, it’s a square. A rather neat one as well.

What I’ve done is optimize memory a bit by using so-called Staging Buffers. These buffers allow transferring data from the HOST_VISIBLE | HOST_COHERENT memory to the DEVICE_LOCAL memory, effectively improving GPU read times. Another thing I’ve done (also the more noticeable one) is implement index buffers! These allow me to reuse vertices and help me draw a beautiful square like this one with just four vertices instead of six.
