Faceted Triangles
Creates a true low-poly surface with flat triangular facets. Each triangle is a distinct flat plane with randomized vertex displacements, producing the iconic paper-craft or polygonal art aesthetic — similar to geometric paper sculptures or low-poly 3D renders.
Parameters
Amplitude- Maximum displacement of the facet vertices in mm (0–10). Higher values create more dramatic, sculptural forms.
Columns- Number of triangle columns around the circumference (2–40). Lower values create larger, bolder facets.
Rows- Number of triangle rows along the height (1–30). Controls the vertical density of the facet grid.
Seed- Randomization seed for vertex displacements (0–100). Change this to generate different facet patterns with the same grid size.
How It Works
The effect creates a grid of vertices across the UV surface and assigns each vertex a deterministic random displacement based on the seed value. Each rectangular cell is split diagonally into two triangles. The displacement at any point is computed via barycentric interpolation from the triangle's three corner vertices.
This guarantees that every triangular face is a true flat plane — the displacement varies linearly across each facet, creating sharp edges where triangles meet. The result is a geometrically accurate low-poly surface rather than a smoothly undulating texture.
