Technical Delaunay mesh for UI

A developer-first product usually reserves color and motion for data and controls, not the background. The technical mesh is the same Delaunay triangulation used in posters and heroes, but with few points, low jitter and reduced opacity so it becomes texture, not the main subject.

What separates "texture" from "composition" in the same mesh

With seed "mesh" and 32 points on the default 720 by 420 canvas, the verified mesh has 52 triangles and about 8.6 KB of SVG, the lightest of the three densities covered here. Fewer points means larger, more spaced-out triangles, the opposite of the "dense faceted" effect a generative poster aims for, and that sparseness is exactly what keeps the mesh discreet enough to sit behind text and code without fighting for attention.
The circumcircle property that governs Delaunay triangulation, no outside point inside any triangle's circumcircle, stays identical at any density: it is what prevents thin, elongated triangles even with few scattered points. That matters more for a technical mesh than for a poster, because one long sliver triangle crossing the background would draw attention exactly where the texture should stay neutral.
Low jitter (near 0%) keeps points close to a regular grid randomized within a small area, producing a more predictable, less "organic" mesh than the 30% jitter used in hero backgrounds. Combined with reduced opacity on the triangle fill, the result reads as a subtle technical grid, closer to a blueprint than to generative art.

Three discretion settings for the technical mesh

Default background texture

Input: seed: mesh, points: 32, width: 720, height: 420, jitter: 10
Expected output: 52 triângulos, SVG de aproximadamente 8,6 KB

This is the lightest density among the three families covered by this tool, built to avoid competing with foreground content.

Even more discreet mesh

Input: seed: mesh-min, points: 18, width: 720, height: 420, jitter: 5
Expected output: Malha próxima do teto teórico de 34 triângulos (2 vezes 18 menos 2)

With low jitter and few points, most sit on the convex hull, so the real triangle count sits very close to the mathematical limit.

Dashboard panel with subtle grid

Input: Malha de 32 pontos aplicada com opacidade de 8% atrás de um painel de métricas
Expected output: Textura de fundo perceptível apenas de perto, sem interferir na leitura dos números

Low opacity is the second control, besides point density, for keeping the mesh in the visual background.

Full tool FAQ

What makes Delaunay different from connecting points randomly?

The empty-circumcircle rule: no point lies inside the circle through a triangle's vertices. That maximizes the smallest angle and avoids extremely narrow triangles, producing a more balanced mesh.

Does the seed guarantee the same result?

Are more points always better?

Can Delaunay be used in UI?

Can the SVG be edited later?

Is the triangulation scientific-grade?

Can the result become heavy?

Does generation use a backend?

Frequently asked questions

How many points should a technical background mesh use to avoid competing with UI controls?

Between 20 and 40 points is usually enough for a discreet background texture on the default 720 by 420 canvas: above that, the mesh gains enough density to read as composition rather than texture, competing for attention with foreground controls.

Why use low jitter instead of the default 30% for a technical mesh?

Because low jitter pulls points toward a more regular distribution, which reads visually as a grid or blueprint rather than an organic composition. The 30% default jitter, better suited to heroes and posters, produces a more irregular mesh that draws more attention, the opposite of a technical background texture's job.

Does the circumcircle property still hold with few points and low jitter?

Yes, it holds regardless of density or jitter: no point in the set may fall inside the circumcircle of any triangle in the mesh, which keeps preventing thin, elongated triangles even in a sparse 20-to-40-point mesh.

Is a 32-point mesh light enough to load behind a data-heavy dashboard?

Yes: the verified 32-point mesh (seed "mesh") produces about 8.6 KB of SVG, lighter than most vector icons in an interface, and being vector it does not get heavier on high pixel density screens the way a PNG at the same resolution would.
