Understanding UV Mapping in 3D Design

UV mapping is the 3D-design process that takes a 3D model's surface and "unwraps" it into a flat 2D layout so textures—like wood grain, fabric patterns, or skin details—can be applied accurately. Think of it as wrapping a gift: the 2D "paper" (texture) must align perfectly around the object.

How It Works (3-Step Process)

1. Unwrapping: You define seams and flatten the 3D surface into UV islands on a 2D plane.

2. Assigning Coordinates: Each point on the 3D mesh gets mapped to a point on the 2D texture.

3. Texturing: The texture is then applied using that UV layout—this ensures precision without stretching or distortion.

UV Mapping Techniques

- Planar – Flat projections, ideal for walls or floors.

- Cylindrical/Spherical – Best for rounded objects like cans or heads.

- Box Mapping – Acts like six-sided wrapping; great for furniture or simple boxes.

Why It Matters

Good UV mapping means realistic, distortion-free textures and better use of texture space—which helps performance in games, film, architecture, and product design.
