- cnn_v3/training/infer_cnn_v3.py: PyTorch inference tool; simple mode
(single PNG, zeroed geometry) and full mode (sample directory); supports
--identity-film (γ=1 β=0) to match C++ default, --cond for FiLM MLP,
--blend, --debug-hex for pixel comparison
- tools/cnn_test.cc: full rewrite, v3 only; packs 20-channel features
on CPU (training format: [0,1] oct normals, pyrdown mip), uploads to
GPU, runs CNNv3Effect, reads back RGBA16Float, saves PNG; --sample-dir
for full G-buffer input, --weights for .bin override, --debug-hex
- cmake/DemoTests.cmake: add cnn_v3/src include path, drop unused
offscreen_render_target.cc from cnn_test sources
- cnn_v3/docs/HOWTO.md: new §10 documenting both tools, comparison
workflow, and feature-format convention (training vs runtime)
handoff(Gemini): cnn_test + infer_cnn_v3.py ready for parity testing.
Run both with --identity-film / --debug-hex on same image to compare.
