Specifying a pipeline vertex binding description, attribute description, and input state

When we want to draw a geometry, we prepare vertices along with their additional attributes like normal vectors, colors, or texture coordinates. Such vertex data is chosen arbitrarily by us, so for the hardware to properly use them, we need to specify how many attributes there are, how are they laid out in memory, or where are they taken from. This information is provided through the vertex binding description and attribute description required to create a graphics pipeline.

How to do it...

1. Create a std::vector variable named binding_descriptions with elements of type VkVertexInputBindingDescription.
2. Add a separate entry to the binding_descriptions vector for each vertex binding (part of a buffer bound to a command buffer as a vertex buffer) used in a given pipeline. Use the following values to initialize its members:
   • The index of a binding (number which it represents) for binding
   • The number of bytes between...
