Stands out in the superhive library for combining a formula-driven equation engine with a NumPy vertex cache built to keep procedural animation stable across frames.
Parametric Shapes & Contour Generator is a Blender addon that converts mathematical formulas and image datasets into fully animated 3D geometry. The equation engine natively evaluates Cartesian and polar multi-variable grids, while organic contours are built from recursive, sliced, and concentric spline generation. Built-in presets include Klein Bottles, Möbius strips, Interference Waves, Amoeba curves, and Coral growths, and grayscale textures can be mapped into topographic heights using Clip, Extend, and Tile wrap boundaries with scale interpolation.
Animation runs on a NumPy-based custom vertex cache (.npc) that preserves complex math topology across time without axis remapping errors. Cached frames are stored in compressed dictionaries and pre-loaded to memory, and auto-animate handlers inject timeline drivers directly into the math variable t. A safe math sandbox pre-compiles and sanitizes every formula before evaluation, capturing syntax or ZeroDivision errors without crashing Blender.
Export routes through Blender's 4.0 and later exporter systems, producing single-frame STL structures or batch OBJ sequence folders for vertex animation in other DCCs. The addon is designed for Blender 4.2.0 and 4.5, and documentation is included.
Parametric Shapes & Contour Generator is best for vFX and 3D artists building math-driven meshes and organic contour geometry in Blender.
Parametric Shapes & Contour Generator is completely free to download and use.
Parametric Shapes & Contour Generator is designed for Blender 4.2.0 and 4.5. Its export utilities integrate natively with Blender's 4.0 and later exporter systems, handling single-frame STL structures as well as batch OBJ sequence folders. If you run one of those releases, the equation engine, contour generation, vertex caching, and export routing are all built to operate within that environment. For any details beyond these listed versions, check the developer's page before installing on a different build.
Parametric Shapes & Contour Generator includes a secure math evaluation module that lets you write custom formulas up to 300 characters, supporting standard operations such as sin, cos, exp, log, and tau. Before evaluation, formulas are pre-compiled and sanitized inside a safe math sandbox, so syntax or ZeroDivision errors are captured instantly without crashing Blender. The equation engine natively evaluates both Cartesian and polar multi-variable grids, and you can inject timeline drivers directly into the math variable t to animate the result over time.
Parametric Shapes & Contour Generator exports to STL for 3D printing and static elements, and to OBJ or continuous OBJ sequences for passing vertex animation data into other DCC applications. Export runs through Blender's 4.0 and later exporter systems, covering single-frame STL structures and comprehensive batch OBJ sequence folders. Generation is one-click, and the baking process uses a spatial hash validation layer to lock non-manifold geometry before exporting begins. This suits both print-ready static output and animated sequences routed into a wider pipeline.
Parametric Shapes & Contour Generator is listed as free in this catalog. Licensing terms can change, so check the developer's page for the current details before you rely on it for production work. On the technical side, the addon is a Blender tool built around an equation engine, organic contour splines, a NumPy-based vertex cache, and STL and OBJ export, with documentation provided alongside it for reference.
