+# Blackwell (sm_120, RTX 50-series) variant of the nerfstudio Docker image.
+#
+# Differences from the stock Dockerfile:
+# - CUDA 12.8 base images (sm_120 requires CUDA >= 12.8)
+# - PyTorch 2.8 with cu128 wheels (ships sm_120 kernels)
+# - COLMAP 3.12.6 / GLOMAP 1.2.0 (CUDA 12.8-compatible releases)
+# - tiny-cuda-nn pinned to a Blackwell-capable master commit
+# - CUDA_ARCHITECTURES defaults to "120"
+# - nerfacc's JIT CUDA kernels are pre-compiled during the build (the
+#   runtime stage has no nvcc, so they could not be built on first use)
+ARG UBUNTU_VERSION=22.04
+ARG NVIDIA_CUDA_VERSION=12.8.1
+# CUDA architectures, required by Colmap and tiny-cuda-nn. Use >= 8.0 for faster TCNN.

+For NVIDIA Blackwell GPUs (RTX 50-series, compute capability sm_120), use the CUDA 12.8-based
+`Dockerfile.blackwell` variant instead — the stock image targets CUDA 11.8, which does not

 ### Using an interactive container
 
 The docker container can be launched with an interactive terminal where nerfstudio commands can be entered as usual. Some parameters are required and some are strongly recommended for usage as following:
