Research direction
Start by reviewing the issue requirements and the linked glTF IBL Sampler, then inspect DirectXTex's existing texture-processing entry points. The initial scope is to determine how a single lat-long HDR image should become a cubemap; PBR IBL texture generation is explicitly optional and should be treated separately.
Written by the indexing model from the issue text.
Description
HDR images (like those downloaded from polyhaven.com) come in lat-long formats that need to be converted into cubemaps. Tools to do so that are frequently cited are often outdated and not supported.
Basically, I think DirectXTex should offer similar functionality as the gltf ibl sampler
I would argue that DirectXTex should offer the ability to generate the PBR ibl textures from the resulting cubemap, but that can be considered more debatable. At the very least, it should be able to create a cubemap from a single lat-long file.
