Texture filtering is a technique used in computer graphics to improve the appearance of textures when they are displayed on 3D models. It helps to reduce blurriness and artifacts that can occur when textures are scaled up or down. Common methods of texture filtering include bilinear filtering and trilinear filtering, which blend colors from surrounding pixels to create smoother transitions. When a texture is viewed from different angles or distances, texture filtering ensures that the image remains clear and visually appealing. This is especially important in video games and simulations, where realistic visuals enhance the overall experience. By applying these techniques, developers can create more immersive environments for users.
