Vulkan Texture Coordinate on the spec

Sorry for being late. I got the summer vacation.

It is obvious for a Monitor. But if you only have stream of bytes in the memory?
Coordinates simply go from 0 to width\height. There’s no left-right direction, there’s no up-down direction. I mean, does C++ array index go from “left to right”, or “right to left”? The question itself would not make sense.

My background on using Graphics API is based on OpenGL. And I learned that the OpenGL has Left-Bottom Texture Coordinate Origin. That’s the reason why I thought there would be a texture coordinate on Vulkan too. But after contemplating your advice, you’re right. Texture colors are just memories. Texture Coordinate also memories. I didn’t even think about the basic of texturing. and that made me confused with this topic.

Plus, Thank you for sharing the spec history!
