茂之钳	08b5854c56	feat(sdf): S12-C PyTorch integration + Python bindings ... Add batch evaluation/gradient functions for SDF trees (sdf_torch.h/cpp). Add sdf_gradient.h with finite-difference gradient utilities. Add Python modules vde.sdf (high-level SDF API) and vde.torch_sdf (PyTorch autograd). Add test_sdf_torch_bridge.cpp with batch eval/gradient tests. Integrate into vde_sdf library and test suite.	2026-07-24 07:20:45 +00:00

茂之钳	6d3f8fc8b3	fix(sdf): use GE/LE instead of GT/LT for smooth blend bounds ... When d1==d2, smooth blend exactly hits k/4 bound at h=0.5, so EXPECT_GE/EXPECT_LE are correct instead of EXPECT_GT/EXPECT_LT.	2026-07-24 07:02:52 +00:00

茂之钳	ebd29e2a21	feat(sdf): S11-B — SDF operations + domain deformations ... Add header-only SDF combinator operations and domain deformation functions based on Inigo Quilez standard formulations: Boolean operations: - op_union (min), op_intersection (max), op_difference (max(-d1,d2)) - Smooth variants: op_smooth_union/intersection/difference with blend radius k with graceful fallback to sharp when k <= 0 Shape modifiers: - op_round (d - r), op_onion (abs(d) - t/2) Domain deformations (coordinate remapping): - op_repeat (infinite grid repetition) - op_mirror_x/y/z (with optional offset) - op_rotate (Y-axis), op_translate, op_scale - op_twist (Y-axis), op_bend, op_cheap_bend - op_elongate, op_displace All functions are inline in include/vde/sdf/sdf_operations.h. Comprehensive unit tests in tests/sdf/test_sdf_operations.cpp covering sharp/smooth booleans, modifiers, domain ops, and composition tests.	2026-07-24 07:02:03 +00:00
