@pmistryNV is there anything I could help with cleaning up your implementation?

[pmistryNV]

@fknfilewalker how are you going to test the extension. Is it on vulkan path?

[fknfilewalker]

Yes vulkan

[pmistryNV]

Yes vulkan

I would like the understand the motivation of how this is going to be used. Can you share some reference code or examples on how this is used in Vulkan?

Using this experimental extension VK_NVX_image_view_handle or I guess texture pointer imported from cuda.
