As an important part of art and design education, environmental art curriculum usually includes many fields such as interior design, landscape design and public art. The current teaching mode is mainly the combination of theoretical teaching and practical operation. The class explanation covers basic knowledge such as art history, design theory and spatial planning, supplemented by case analysis to guide students to understand design principles. In practice, students exercise their design thinking and expression ability through hand-drawn sketches and model making. In addition, some of the courses also take the form of group cooperation to develop teamwork and project management skills. MATLAB simulation shows that under the condition of certain evaluation criteria, computer three-dimensional software technology has a rational effect on environmental art design The feasibility of artistic design is better than traditional design methods.
