The Camera in a game is the main tool used to capture Scenes. The visible range of the Camera is controlled by adjusting camera-related parameters. The Camera is represented as follows in the Cocos Creator 3D editor:


The Camera's visual range is composed of 6 planes forming a Frustum, a Near Plane, and a Far Plane to control the visible distance and range of near and far distance, at the same time, they also constitute the size of the viewport.

Camera components

The Camera Component is an important functional component that we use to present a Scene.

camera component

Parameter Description
ClearFlags Camera clear logo. Contains:
DONT_CLEAR: not clear;
DEPTH_ONLY: only clear the depth;
SLOD_COLOR: clear the color, depth and template buffer
Color Clear the specified color
Depth Clear the specified depth
Stencil Clear the specified template buffer
Far Far cutting distance
Near Near cutting distance
Fov Angle of view
OrthoHeight The height of the orthogonal Camera
Priority Priority. High-priority Cameras will be rendered first in the rendering process
Projection Projection mode. Divided into perspective projection (PERSPECTIVE) and orthogonal projection (ORTHO)
Rect Viewport size of Camera
Visibility The visibility of the Camera. Used to control the visibility of different models in the same Camera.

Camera group rendering

The Camera's group rendering function works with the Model Component through the Visibility property of the Camera Component. The user can set the Visibility value through code to complete the group rendering. It should be noted that the Visibility value is bitwise comparison, and the user can manipulate the top 20 bits of Visibility through bit operations to complete the grouping.

The Camera and models provided by default are all rendered without grouping. You do not need to change this value if the game has no special requirements to do so.
