TPMS generation

[mohdibntarek]

Description

Add support for triply periodic minimal surface (TPMS) lattice generation, including Gyroid, Schwarz Primitive, and Schwarz D surface families, with controllable thickness and grading.

Context

Available in nTop and some generative-design systems. TPMS structures offer excellent mechanical and thermal properties with smooth, self-supporting geometry ideal for additive manufacturing.
