Indirect rendering in Vulkan
Indirect rendering is the process of issuing drawing commands to the graphics API, where most of the parameters to those commands come from GPU buffers. It is a part of many modern GPU usage paradigms, and it exists in all contemporary rendering APIs in some form. For example, we can do indirect rendering with OpenGL using the glDraw*Indirect*() family of functions. Instead of dealing with OpenGL here, let's get more technical and learn how to combine indirect rendering in Vulkan with the mesh data format that we introduced in the Organizing the storage of mesh data recipe.
Getting ready
Once we have defined the mesh data structures, we also need to render them. To do this, we allocate GPU buffers for the vertex and index data using the previously described functions, upload all the data to GPU, and, finally, fill the command buffers to render these buffers at each frame.
The whole point of the previously defined Mesh data structure is the...
