existManimmiddle,CameraIt is one of the important tools to achieve animation effects.
It's like we observe animationEye, by controlling the camera's position, angle and field of view, you can create a rich and diverse visual effect.
ManimA variety of available in the community versionCameraTypes, each has its own unique functions and application scenarios.

Camera: Standard camera -
MappingCamera: Mapping camera -
MultiCamera: Multi-camera -
MovingCamera:Mobile camera -
ThreeDCamera: 3D camera
Subsequent articles will introduce the use of each different camera in detail.
This article first introduces various differences in the overallCameratypes, their differences and application scenarios.
1. Standard camera
Standard camera（CameraClass) isManimThe most basic camera type is mainly used in 2D scenes.
Its default focus is in the center of the screen, viewing all elements from a top view.
Standard cameraThe main feature is its simplicity and stability, suitable for most regular 2D animation productions.
For example, when creating simple geometric transformation animations, a standard camera can meet the needs well, which can clearly show the position, size and shape changes of the figure.
2. Mapping the camera
Mapping camera（MappingCameraClass) is a special type of camera that allows mapping between different objects.
This kind of camera can be used to implement some special visual effects, such as mapping a 2D graphics onto a 3D surface, or mapping a complex animation effect onto another object.
Mapping cameraThe main features are flexibility and creativity, which provides animation makers with more creative space to achieve some unique visual effects.
3. Multi-camera
Multi-camera（MultiCameraClass) allows multiple cameras to be used simultaneously in the same scene.
Each camera can have different viewing angles, field of view and focus, thereby achieving multi-view observation effects.
For example, when creating a complex animation with multiple subscenes, you can use multiple cameras to display the details of each subscene separately, and then present the overall effect by switching or fusing the pictures of those cameras.
Multi-cameraCan also be used to implementHawkeyeEffects, that is, displaying local details and global views at the same time, are very useful when presenting complex systems or processes, allowing the audience to better understand the relationship between various parts.
4. Mobile camera
Mobile camera（MovingCameraClass) is an extension based on standard cameras that enable animation effects by changing the position and angle of the camera.
Mobile cameraThe main functions include changing the focus and field of view. Changing the focus allows a specific element to always be in the center of the screen, just like we use our camera to track a moving object;
Changing the field of view can achieve the zoom effect, allowing the audience to feel the changes in the distance of the object.
Mobile cameraIt is very useful when creating complex animations, such as when showing an object moving along a complex path,Mobile cameraIt can better guide the audience's attention and enhance the expressiveness of the animation.
5. 3D Camera
3D Camera（ThreeDCameraClass) is a camera type designed for 3D scenes, which can move and rotate freely in three-dimensional space.
By adjusting3D CameraThe position, angle and field of view can achieve various complex 3D viewing effects.
For example, when presenting a 3D model, you can use a 3D camera to observe the details of the model from different angles, or to display the dynamic effects of the model by rotating the camera.
3D CameraIt also supports some special 3D animation features such as depth perception and shadow effects, which can further enhance the reality and visual impact of 3D scenes.
6. Conclusion
ManimIn-houseCameraThe function provides powerful support for animation production. By rationally selecting and using different Camera types, various rich visual effects can be achieved to meet the animation needs in different scenarios.
Finally, sort out the differences and application scenarios of various cameras:
| Camera Type | Features | Main scenes |
|---|---|---|
| Standard camera | Simple and stable, fixed viewing angle and field of view | Regular 2D animations, such as geometric transformation |
| Mapping camera | Supports mapping between objects | Special visual effects such as 2D graphics mapped to 3D surfaces |
| Multi-camera | Supports multiple cameras to achieve multi-view angle | Multi-view display of complex scenes, hawkeye effect |
| Mobile camera | Can change focus and field of view | Track moving objects and show changes in distances and distances |
| 3D Camera | Can move and rotate in three-dimensional space | 3D scene perspective adjustment to display 3D models |
