WebDec 31, 2016 · The dynamic uniform buffers are made for this? I read th. hello. I'm trying to create an indirect drawing with vulkan. All works fine but now i would create some states variables to send per objects drawing. For example : if i have 3 cubes and i would change the color only at the first, how i can do? The dynamic uniform buffers are made for this? Lets refactor the code for the scene buffer to use dynamic uniform descriptor and not hardcode the offsets. The first thing to do is to reserve some size for dynamic uniform descriptors in the descriptor pool. In init_descriptors(), change the descriptor sizes for creating the descriptor pool to this Dynamic uniform buffers are a … See more To know what is the minimum alignment size for buffers, we need to query it from the GPU.
