Three-dimensional animation software first establishes a virtual world in the computer. Designers build models and scenes in this virtual three-dimensional world according to the shape and size of the objects to be represented, then set the motion trajectory of the model, the motion of the virtual camera and other animation parameters as required, and finally specify specific materials for the model and illuminate it as needed. When all this is done, the computer can automatically calculate and generate the final picture.

Effective steps of 3D animation:

3D Animation-Steps 1: Modeling

Modeling requires modeling software, such as Autodesk-Maya, Mudbox and Zbrush. Start with basic geometry (cubes, cylinders, etc.). ), stretch, cross-section, rotate, synthesize and add lines to build a model. The model should be as simple and efficient as possible, and there should be no redundant points, lines and surfaces, otherwise it will bring trouble to paste materials and render later.

3d Animation-Step 2: Binding

The model of a character is generally like the big font above, and it is completely moved by rigging (binding). This work is highly technical. Firstly, the skeleton of the character should be established: after the skeleton and various control points are completed, the skin should be made, and the influence degree of each control point on the muscles and bones should be drawn on the model.

3D Animation-Step 3: Animation

Generally, the actions performed by real people will be recorded first, and then animation will be started according to the real people's actions. And many times, it is the animator himself. Animation is a way of performance, so animators are very talented. Animation is the soul of a work. Only when the animation is convincing can the characters live. The design and execution of every wink and every little gesture is the key to embody the role. This is why Pixar and Disney's works are so spiritual.

3d Animation-Step 4: Materials, Lighting and Rendering

These three aspects are inseparable. With real materials, the picture has credibility, and with lighting, there is atmosphere and story. In addition to distinguishing how to create an atmosphere and a picture like a movie lighting engineer, a lighting engineer also simulates the real lighting effect by controlling the type, intensity, shape, color, reflection mode and shadow of light. Adjusting the physical properties of materials can simulate different effects: metal, plastic, leather, glass, etc. In live-action movies, materials and lighting are also the key to make the model achieve the effect of confusing the real with the fake. You can't see the effects of lights and materials until you render them.

3d Animation-Step 5: Blending

Synthesis is the last step and a very important step, which can turn decay into magic. Combine the rendering layer, adjust the lack of light and materials, and combine the background and special effects with the picture.

3d Animation-Step 6: Edit

Put all the rendered shots together, adjust the overall tone, dubbing, soundtrack, add titles, subtitles and staff. This is the general process of making computer animation.
