Test requirements:     1. From the files in the "experimental images" directory, select 2 as the experimental data. For each selected image, each clustering algorithm (maximum and minimum distance method, C-means method) and each given image are used a. clustering algorithm is used to cluster the (R, G, B) color vect ...

Operation requirements: 1. Three texture filtering methods are used to load textures (linear sampling, mipmap and nearest point sampling); 2. The image loaded with texture can be set by yourself; 3. The texture of each face is different; 4. The mouse or keyboard controls the switching of texture filtering methods. Initialize OpenGL Sa ...
