regcore_cuda.dll — GroundTex CUDA backend (Windows x64)

Ground-texture RegCore on CUDA. The fastest backend when an NVIDIA GPU is present.

Requirements

• NVIDIA GPU, compute capability 6.0 or newer (sm_60)
• CUDA 12.4 runtime (the DLL links cudart_static and cufft)

If you have no NVIDIA GPU, use GtexCPUPlugin (Windows) / regcore_cpu_linux (Linux), or regcore_sycl on Intel integrated graphics.

Install

Drop regcore_cuda.dll next to DetourLite.exe.

Selecting it

DETOUR_REGCORE picks the backend, comma-separated for a fallback order:

DETOUR_REGCORE=cuda            # this DLL only
DETOUR_REGCORE=cuda,gtex_cpu   # CUDA if it loads, else the CPU plug-in
DETOUR_REGCORE=auto            # discovery order

Aliases: cuda, regcore_cuda. The console reports the winner:

RegCore backend candidates: cuda:..., sycl:..., gtex_cpu:...

What changed in this build

Retargeted from CUDA 10.2 / MSVC v142 to CUDA 12.4 / v143 — the old pin is why this project silently dropped out of Detour.sln and stopped being built at all.

CUDA 12 removed the legacy texture-reference API. The only thing using it was a vendored OpenCV helper (clahe/common.hpp's bindTexture) with no call sites anywhere in the project; the project's own kernels already use texture objects. It is now compiled out on CUDA 12 and newer. No kernel or algorithm changed.

The CUDA version is no longer hardcoded: build with /p:DetourCudaVersion=12.4 (or whatever you have installed).
