Texture mapping is a fundamental technique in 3D graphics that involves applying a 2D texture image onto a 3D model’s surface. Various methods of texture mapping are used to achieve different visual effects and fit specific modeling needs. Here are some common types:
- Planar Mapping: Planar mapping projects a texture onto a 3D model from a single plane. This method is best for objects with flat surfaces or simple shapes, as it creates a straightforward and distortion-free texture application.
- Cylindrical Mapping: Cylindrical mapping wraps a texture around a 3D model like a cylinder. This technique is ideal for objects with circular or cylindrical shapes, such as bottles or pipes, providing a seamless texture that follows the curvature of the model.
- Spherical Mapping: Spherical mapping projects a texture onto a 3D model in a spherical fashion. This approach is suitable for objects that approximate a sphere or rounded shape, such as planets or balls, allowing for a consistent texture application across the surface.
- Box Mapping: Box mapping applies textures to a 3D model from multiple sides, similar to wrapping a box with paper. This method is effective for objects with a box-like or rectangular shape, ensuring textures cover all six faces of the model.
- Tri-Planar Mapping: Tri-planar mapping applies textures from three different planes (X, Y, and Z axes) to seamlessly cover a 3D model. This technique is particularly useful for complex surfaces or irregular shapes, minimizing texture distortion and ensuring a cohesive appearance.
