VkVertexInputBindingDescription

VkVertexInputBindingDescription is a data structure used in the Vulkan graphics API to specify how vertex buffer data is bound during rendering. It describes the binding point, the stride (the size in bytes between elements), and the input rate, which determines whether vertex attributes are advanced per vertex or per instance.

This structure contains the following fields:

- binding: an unsigned integer that uniquely identifies the binding point.

- stride: the byte size between consecutive elements within the buffer.

- inputRate: specifies whether the binding advances per vertex (VK_VERTEX_INPUT_RATE_VERTEX) or per instance (VK_VERTEX_INPUT_RATE_INSTANCE).

VkVertexInputBindingDescription is typically used in conjunction with VkVertexInputAttributeDescription structures, which define the format and location of individual vertex attributes within the buffer. Together, these descriptions inform the Vulkan pipeline how to interpret raw vertex data.

Developers include an array of VkVertexInputBindingDescription structures in the pipeline creation process, specifically when configuring the VkPipelineVertexInputStateCreateInfo structure. Proper configuration ensures that vertex data is correctly read and interpreted during rendering, optimizing performance and correctness.

This structure plays a crucial role in the flexible and efficient management of vertex data, supporting various buffer layouts and input rates to accommodate different rendering techniques and resource management strategies within Vulkan applications.
