Use RTX directly (without Optix, DirectX, Vulkan)?


I’m trying to look into how RT cores can be used to accelerated ray-tracing along sparse voxel grids, such as GVDB or NanoVDB. Is there any documentation on how I can use RT cores / RTX acceleration for speeding up ray tracing on custom programs? Most RTX documentation I look at points me towards Optix, DirectX, etc for leveraging the technology.

Thanks in advance!
