Onsite usage and simulation playback

This article introduces the configuration differences of Mega during onsite usage and offsite simulation playback, and how to configure based on requirements.

Differences between onsite usage and simulation playback

Mega uses GNSS (GPS, BeiDou, etc.) information to assist the localization process, improving its accuracy and stability. During onsite usage, the device's GNSS information is accurate and can assist localization. However, during offsite simulation playback, the device's GNSS information doesn't match the environment. This data cannot assist localization and may negatively impact localization results. Therefore, Mega provides two different configurations to meet the needs of onsite usage and offsite simulation playback.

The default configuration is the simulation playback configuration, avoiding localization failures caused by incorrect configurations during initial use.

In the simulation playback configuration, a warning message will always appear on screen. This message cannot be turned off to ensure applications aren't released to end-users with incorrect configurations.

Tip

To disable the warning message, ensure the application will only be used onsite and use the onsite configuration.

Configuration for offsite simulation playback

Select the Mega Tracker object under the session, find the MegaTrackerFrameFilter component, and choose Simulator for Location Input Mode to enable the simulation playback configuration.

In scripts, you can achieve the same effect by setting MegaTrackerFrameFilter.LocationInputMode to Simulator.

Note

When using EIF files for simulation playback, this option is automatically set to FramePlayer and cannot be changed, ensuring correct usage of GNSS data recorded in EIF files.

Configuration for onsite usage

Select the Mega Tracker object under the session, find the MegaTrackerFrameFilter component, and choose Onsite for Location Input Mode to enable the onsite usage configuration.

In scripts, you can achieve the same effect by setting MegaTrackerFrameFilter.LocationInputMode to Onsite.

Caution

Using the onsite configuration incorrectly during offsite simulation playback may cause localization failures, affecting content display.
