#### 透视¶

This matches how you view things in the real world. Objects in the distance will appear smaller than objects in the foreground, and parallel lines (such as the rails on a railroad) will appear to converge as they get farther away.

Tip

## 摄像机¶

This setting is an alternative way to control the focal length, it is useful to match the camera in Blender to a physical camera & lens combination, e.g. for motion tracking.

## 景深¶

Real-world cameras transmit light through a lens that bends and focuses it onto the sensor. Because of this, objects that are a certain distance away are in focus, but objects in front and behind that are blurred.

Hint

## 显示¶

3D视图中摄像机可视化的大小。此设置对摄像机的渲染输出 没有 影响。摄像机可视化也可以使用标准缩放 S 键进行缩放。

### 构图辅助线¶

Draws a diagonal line from the lower left to upper right corners, then adds perpendicular lines that pass through the top left and bottom right corners.

Draws a diagonal line from the lower left to upper right corners, then lines from the top left and bottom right corners to 0.618 the lengths of the opposite side.
