Math Examples¶

The nodeforge.math package includes complete example scripts in the Examples catalog. Install the Math package, then open Library → Examples to add an example as a Geometry Nodes group.

Examples are complete scripts intended for inspection and adaptation. To view an example source, add it from the catalog, select the generated group node, and use Load Script From Selected NodeGroup.

dna_double_helix¶

Builds a parametric DNA-style double helix from two backbone strands and repeated base-pair rungs. The controls set the base-pair count, helix radius, rise, twist, phase, and element thicknesses.

fibonacci_spiral¶

Distributes instances of the input Geometry along a sunflower-style Fibonacci spiral. The point count, radial scale, instance scale, and angular turn are runtime controls.

helix_ladder¶

Builds a helical ladder or spiral-stair structure from radial rungs, outer posts, and a central post. The step count and the main shape parameters remain runtime inputs.

kinetic_louver_wall¶

Creates a rectangular field of thin facade blades. A pair of trigonometric fields controls the tilt of each blade from its position, producing a wave-like kinetic-louver pattern.

mandelbrot¶

Evaluates the Mandelbrot set over a generated grid with a runtime Repeat Zone. Resolution controls the grid density and Max Iter controls the iteration limit used to classify and color the cells.

This example is packaged as examples/mandelbrot/source.nf with a package-local Python backend used only to create and assign its display material. The fractal iteration itself is written in the NodeForge DSL.

noise_terrain¶

Generates a mesh grid and displaces it vertically with layered, domain-warped 3D noise. Runtime controls expose grid resolution, height, noise detail, roughness, warp strength, and domain offsets.

parametric_truss_bridge¶

Builds a through-arch truss bridge with an explicit road deck, curbs, side trusses, vertical posts, arched top chords, diagonal bracing, and overhead cross-ties. The number and width of bays define the span, while the remaining controls shape the arch and structural members.

rippled_tile_field¶

Creates a centered grid of tile instances and drives their height and vertical scale with a radial sine wave. A smooth radial falloff reduces the wave toward the outside of the field.

sierpinski_carpet¶

Applies the eight-cell Sierpinski-carpet offset pattern repeatedly to the input Geometry. Steps is a runtime input, and Scale controls the per-iteration copy scale.

topographic_contour_stack¶

Builds stacked closed contour rings from runtime point grids. Each ring uses several periodic waves to vary its radius, and short tangent-aligned segments overlap to form continuous-looking contour lines.
