Watercolour takes water as the medium to convey the emotion and thought of the work through different materials, colours, textures and textures. With the more and more extensive application of computer technology in 3D animation, people have higher and higher requirements for colour. Therefore, this paper mainly studies the performance of watercolour art in computer software aided design and 3D scene rendering. Firstly, this paper introduces the definition and style characteristics of watercolour art, then expounds the application of watercolour art in computer 3D animation design system, then studies the application of 3D animation technology, designs the frame diagram of computer 3D animation design system based on this, and investigates the application scene of watercolour art in 3D animation design. Finally, the survey results show that most people believe that the most application scene of watercolour art in computer 3D animation is three creative scenes, namely, artistic conception creation, virtual reality combination creation and space level sense creation. This is because watercolour has the characteristics of transparency, nature and obscurity. In animation creation, its unique language forms and techniques can be used to express the artistic form and atmosphere needed in the scene.
