Tile Comparison

Overview

The Tile Comparison feature allows users to visually compare two assets within the same scene using an interactive split-screen workflow. Once two assets are selected and linked, a movable slider is enabled that divides the viewport into two regions. Each side of the screen is associated with one of the selected assets, ensuring that only the corresponding asset is visible within its respective region. As the slider is adjusted, the visible boundary updates in real time, allowing users to directly compare differences between the two assets, even when they occupy the same physical space in the scene.

Features

• Select and link two assets for comparison

• Enable an interactive, movable slider to divide the viewport

• Display one asset exclusively on each side of the slider

• Dynamically update asset visibility as the slider is moved

• Support overlapping assets while maintaining correct visual separation

• Allow real-time, side-by-side comparison within the same scene

How to Use

Open the Actions menu and select Tile Comparison. Once selected, the Tile Comparison panel will appear on the right side of the screen, indicating that the feature has been activated and is ready for asset selection and comparison.

You will then be presented with two methods for selecting a material (or asset) to use in the comparison. You may either use the dropdown menu to choose a solution from the available list, or select Set, which enables a selection mode allowing you to click directly on an asset within the scene. When using the Set option, the clicked asset will be assigned to the corresponding comparison slot, streamlining selection when assets are already placed in the environment.

Selecting the dropdown menu displays a list of all assets associated with your active Cesium token. You can scroll through the available options to review the tilesets and datasets accessible to your account. Once you have identified the desired asset, click on it to assign it to the corresponding comparison slot.

To select an asset directly from the scene, click Set to enable selection mode. While this mode is active, click on a valid Cesium tile within the scene to assign it to the corresponding comparison slot. The selected tile will be linked automatically, allowing it to be used in the Tile Comparison workflow.

If you need to locate a specific asset, click the Search icon to open the search field, then enter the asset name into the search bar. The list will update dynamically to display matching results, allowing you to quickly find and select the desired asset for comparison.

After entering a search query, the filtered results will not be immediately visible. To view the updated results, you must reopen the dropdown menu. Additionally, note that clicking the Search icon again will clear the current search results and reset the list, so be sure to reopen the dropdown before modifying or reissuing your search.

Once both tiles have been set, the system will automatically reposition the camera to the location of the left asset. If the left asset does not have a valid location, the camera will instead move to the location of the right asset. If neither asset provides a valid location, the camera will remain at its current position.

Once you click Begin at the bottom of the Tile Comparison panel, a vertical slider will appear in the center of the screen, dividing the viewport into two sections. The left side displays the first assigned asset, while the right side displays the second asset. You can drag the slider horizontally to adjust how much of each asset is visible, enabling direct, side-by-side comparison in real time. When you are finished comparing, click Pause (located where the Begin button was) to stop the slider interaction and freeze the current view.

When you are finished with a comparison and would like to start a new one, click the Reset button at the bottom of the Tile Comparison panel. This action clears and unlinks the currently assigned assets from both the left and right tiles, returning the feature to its initial state and allowing you to select a new pair of assets for comparison.
