Block Models, Stairs and Mesh Optimizations

Описание: In this video I demonstrate you the new block models and stairs and I explain how I store my chunk meshes in memory.

There is a simple optimization that is often missed by other developers.
To highlight this I show how 3 different, well-known engines store their meshes and how they could reduce them by 4× to 6×:
‪@Hopsonn‬ → "Minecraft in a week" and "Let's code Multiplayer C++ Voxel Game"
‪@finalforeach‬ → "Cosmic Reach"
‪@VintageStory‬ → "Vintage Story" (obviously)
The optimization in question is quite simple, as it just involves using buffers to store repeated values, something (the same people) are already doing quite comfortably on the CPU.
But for the GPU it is a common misconception that this is not possible, but it is!
That's why I made this video.

And of course I need a place to show off the chiseled stair system I made :​P

If you want to learn more, the technique is also often called vertex pulling. Additionally you can check out my shader code here: https://github.com/PixelGuys/Cubyz/bl...
