`simvx.graphics.gpu.descriptors`¶

Descriptor pool, layout, and set management.

Module Contents¶

Functions¶

`create_descriptor_pool`	Create a descriptor pool for SSBO descriptors (+ optional image samplers).
`create_ssbo_layout`	Create a descriptor set layout with N SSBO bindings + optional sampler bindings.
`allocate_descriptor_set`	Allocate a single descriptor set from the pool.
`create_texture_descriptor_pool`	Create a descriptor pool for combined image samplers.
`create_texture_descriptor_layout`	Create set layout for texture array (fixed-size combined image samplers).
`write_texture_descriptor`	Write a single texture to the texture array at the given index.
`write_image_descriptor`	Write a combined image sampler to a descriptor set at the given binding.
`write_ssbo_descriptor`	Write a single SSBO buffer binding to a descriptor set.
