Texture Mapping
Texture mapping is a computer graphics technique that applies a 2D image (called a texture) onto the surface of a 3D model to add detail, color, and realism without increasing geometric complexity. It involves mapping texture coordinates from the 2D image to the vertices of the 3D mesh, allowing for effects like wood grain, brick patterns, or skin textures. This process is fundamental in rendering realistic scenes in video games, simulations, and 3D visualizations.
Developers should learn texture mapping when working in 3D graphics, game development, or virtual reality to enhance visual quality and performance by using textures instead of complex geometry. It is essential for creating immersive environments in engines like Unity or Unreal Engine, and for applications in architectural visualization, film production, and medical imaging where realistic surfaces are critical.
