1a1b只需執行hw4_part1.m 會依序出現 lowSamp&lowLoD lowSamp&highLoD lowSamp&highLoD bI bII 的結果
2a請執行makeRGBCube.m 2b請執行makeHSVCylinder.m 2c~2e請執行readOBJFile.m 依序出現 2c 2d position light-> directional light 2e I. (ka , kd , ks) = (1.0, 0.0, 0.0)-> II. (ka , kd , ks) = (0.1, 1.0, 0.0)-> III. (ka , kd , ks) = (0.1, 0.1, 1.0)-> IV. (ka , kd , ks) = (0.1, 0.8, 1.0)
