# TorchCurves: Differentiable Parametric Curves > Source: > Published: 2026-11-11 13:00:05+00:00 We present TorchCurves, a PyTorch library that treats vector-valued parametric curves as learnable primitives. Its central operation maps batches of scalar inputs to points on curves represented in B-spline or Legendre polynomial bases, with differentiation through both inputs and coefficients. Curv
