Islamic Geometric Pattern vs Op Art
イスラム幾何学文様 / オプ・アート
Islamic Geometric Pattern comes from Ornament and Op Art from Geometric Abstraction. One is technique and the other style. They are reached for with different intent, which is the fastest way to tell them apart.

| Islamic Geometric Pattern | Op Art | |
|---|---|---|
| Era | 8th century– | 1960s– |
| Family | Ornament | Geometric Abstraction |
| Kind | Technique | Style |
| Cues | Compass construction / Star forms / Repeating units / Interlacing lines | High contrast / Repeated lines / Optical illusion / Geometric distortion |
| Best used for | Filling walls and ceilings so the surface reads continuous, with no visible seam. · Deriving screens and modular building parts from a single repeating unit. | Key visuals that stop the eye hard · Implying sound and motion in a still |
| Type | If lettering enters, give it its own band and leave the grid intact. | Keep a neutral sans away from the illusion zone |
| Composition | Derive the unit from the construction circle and size the field in whole units. | Deform one repetition rule gradually |
| Material | Pierced stone, assembled wood, inlaid tile, crossings shown as level changes. | Black and white plus exactly one color |
| Caution | Star shapes pasted together without the construction leave lines that miss at the crossings, and the error multiplies when repeated. The Islamic world is not one culture, so check region, dynasty, material and use. | Never let the vibration reach the reading zone. Lower area and contrast on long-viewed screens. |
