Tip : Select the right side of the directory, you can quickly find what you need
This series of blog Address: Portal
: This program is the basis of the configuration of the project, to facilitate our future development.
A, SDK environment configuration
Install the necessary SDK.
a、Windows--Packages：
Advanced：Show preview packages
b, installation ARFoundation, ARCoreXRPlugin, ARKitXRPlugin.
ARFoundation etc. The default is the current version validated (verified). We unified the above package selection See all versions, select 3.1.0, Install.
Second, the scene configuration
1, component lifecycle
Level panel to delete the original video cameras, right-XR, add AR the Session Origin , AR the Session .
Both components contain cameras, ARFoundation life cycle and more. We often fall after the functions of the two components of the object.
2, to achieve the detection point cloud displayed
A, ARSessionOrigin object added ARPointCloudManager assembly
This assembly feature is implemented to detect and display the point cloud. But what kind of point cloud? Then we need to step b configured.
B, level right panel XR-AR Default Point Cloud, made the object point cloud preform , delete the object hierarchy panel. The preform assembly assign ARPointCloudManager
3, to achieve detection display plane
A, ARSessionOrigin object added ARPlaneManager assembly
Similarly, what kind of plane? Step b needs to be configured.
B, level right panel XR-AR Default Plane, the object made flat preform , delete the object hierarchy panel. The preform is assigned to ARPlaneManager assembly
DetectionMode: Control test showed a horizontal plane, vertical plane, are detected or not detected.
4, resource control
Above we do is to achieve a device to detect a real environment feature points, planar, and flat display point cloud.
Then we also need to control these detected point cloud, plane, so they hide or display.
So we write a script that provides Public disclosed methods, help us control these objects .
This script is free to hang in what will do. Script functions are as follows:
- Offers: Enabling and disabling the detection plane
- Provided: display plane detected by the Hide
- Yield: AR current session is in progress, and tracked (i.e., the device can determine its current position and orientation in the world)
- Automatic operation: Check the equipment operating environment, can support ARFoundation
- Automatic operation: contains one power-saving strategy, identify the target when the device is not found, allow the screen to dim after a period of time last active
