vkCmdPipelineStatistics

VkCmdPipelineBindDescriptorSets is a Vulkan command used to bind descriptor sets to a command buffer for use with a graphics or compute pipeline. Descriptor sets are collections of resources, such as shader buffers and textures, that shaders can access. When this command is invoked, the specified descriptor sets are associated with the pipeline bind point and the pipeline layout. The pipeline layout defines the structure and types of descriptors that the pipeline expects.

The command takes several parameters. The command buffer is the target into which the command is recorded. The pipeline bind point indicates whether the descriptor sets are intended for the graphics pipeline or the compute pipeline. The first set parameter specifies the index of the first descriptor set to be bound. The descriptor set count indicates how many descriptor sets are being bound, starting from the first set. Finally, an array of VkDescriptorSet handles provides the actual descriptor sets to be bound.

When a rendering or compute operation is later executed using the command buffer, the bound descriptor sets will be accessible to the shaders currently active in the bound pipeline. This allows shaders to reference data and textures that have been previously set up in the descriptor sets. It's crucial that the descriptor sets being bound are compatible with the pipeline layout associated with the currently bound pipeline. Mismatches can lead to undefined behavior or validation errors. This command is typically used before issuing draw or dispatch calls that will utilize the bound descriptors.
