UV Mapping Techniques

UV Basics

• UV Coordinates: 2D coordinates mapping 3D geometry to 2D texture space
• UV Unwrapping: Process of flattening 3D geometry into 2D space
• UV Seams: Cuts in UV layout to enable flattening
• UV Islands: Connected groups of UV faces
• UV Density: Consistency of texel density across model
• UV Space: 0-1 coordinate space for UV mapping

UV Unwrapping Methods

• Automatic Unwrapping: Algorithmic UV generation
• Manual Unwrapping: Manual seam placement and unfolding
• Projection Mapping: Project UVs from different views
• Cylindrical Mapping: Wrap UVs around cylinder
• Spherical Mapping: Wrap UVs around sphere
• Box Mapping: Project UVs from 6 directions
