Thank you for participating in the 3D Animation camp. 3D Modeling and Animation are trendy, and the demand from industries is increasing. 75% of IKEA catalog photos are 3D models, many movies and advertisements using 3D models and animations, games fully rely on it, and manufacturing processes are changing with 3D technologies. We wish your son's wonderful future.

Thank you very much for writing the review. RISU is glad to know that she enjoyed the camp. 3D Animation is not easy and requires a lot of knowledge. RISU hopes that she enjoys developing her own animation. We look forward to seeing her in the 3D Modeling and Special Effects camp.

Love the classes and would recommend them to others!! My daughter took the basic and advanced scratch programming courses and absolutely loved it. Now she has really taken to programming and wouldn’t stop until we ask her to step away from the computer. The classes were engaging and fun and the instructors were very patient.
