Abstract-This paper introduces a "low memory" 3D animation design technology teaching system, and fully describes the design requirements, design thought, and main modules of the system. On this basis, an analysis of the teaching process of applying the system in animation design curriculum in universities is made with the method of contrastive teaching experiment. Results show: comparing with traditional multimedia teaching method, the application of "low memory" 3D animation design technology significantly improves the effectiveness of animation design teaching. This teaching method is of prominent innovative value, and worth to be further popularized and applied in teaching.
