Simulating 3D content effects
Annotation data is structured data files created using the Mega Studio tool, primarily used to record spatial positioning information such as location coordinates and pose parameters of target objects within a scene. During simulated positioning tests, this annotation data can also serve as a benchmark reference to verify the accuracy of actual positioning effects.
Preparation before annotation
Before starting to create annotations, you need to ensure that the corresponding environment and data are prepared.
If you need to display annotation data during positioning, you can use the annotation component for annotation. Before this, you should have completed EIF data recording and followed the instructions in Simulation run to complete the configuration preparations for the software environment.
Annotation data process
Right-click in the blank area of the left panel "Hierarchy" and import "Annotation Tool(Edit Mode)"

Select "EasyAR.Mega.Annotation" in the left panel "Hierarchy"
Enter your EasyAR account name and password in the right panel "Inspector"
Click "Login"

In the right panel "Inspector", click the icon after "Mega Cloud Service"
In the opened window, select a "Mega Block localization service"
Click "OK"
In the right panel "Inspector", click "Load" to add the map to the Unity project

Create annotation data
Press Ctrl and left mouse button simultaneously at the spatial position needing annotation to create an annotation cube

Create 3D objects via the right-click menu. Note that 3D objects must be placed under the Block node

Directly import pre-generated models

Select "EasyAR.Mega.Annotation" in the left panel "Inspector", then click the icon after the annotation data package in the right "Inspector" panel
In the opened window, select a "Mega Block localization service" on the left

Click the "+" symbol in the upper right corner to create an annotation data package
Enter the name of the annotation data package
Click the "√" symbol to confirm
Click "OK" to save the annotation data package

Note
If you need to save annotation data, you can click below the annotation data package in the right "Inspector" panel and click the "∧" symbol
Finally, click "Yes" in the pop-up window to complete saving the annotation data package

Viewing positioning effects using annotation data
This part of the operation is similar to Simulation run. For more detailed steps, refer to the previous chapter.
First enable the tool, then click the run button to start

You can also start via the button on the Unity toolbar

Open and automatically play EIF

Playback can be controlled as needed. The typical effect will look like this
You can also completely hide the Block model, making the effect consistent with what is seen in a real scene
Stop the run via the tool button

Summary and best practices
Finally, if you need to develop your own application and run your program in the editor, you need to disable the validation tool (only effective in the editor, does not affect mobile device effects).
