FVS 3D Background Application

This document is applicable to users who have installed the FineVis Data Visualization plugin to learn plugin functions.

Application Scenarios

When creating a 3D template, you may add the same 3D component in multiple pages and smoothly switch different views through the Smooth Transition animation.

But repeated addition of models requires repeated setting of model effects, and if one of the models is modified, the rest must be synchronized, causing low production efficiency and high maintenance costs.

After you add a 3D component in the 3D background page, set its effects and events, apply the background to multiple pages, and set the current page effect in pages, the models, data, and animation effects can be referenced from the background page. In this case, you can achieve the smooth transition effect without enabling Smooth Transition.

Function Entry

To select 3D Background as the page background for the first time, you need to click Add 3D Background to open the 3D background setting page.

After opening the 3D background setting page, you can switch the canvas page through Page/3D Background under the canvas. After that, even if the page background is set to other options, the 3D background page will not be closed.

Function of 3D Background Page

You can add multiple background pages, set the background page name and page background (except 3D background).

Only 3D City Scene component or Custom 3D Scene component can be added to a background page. Only one 3D component is supported in one background page. And you can paste one of them copied from a page in a background page.

A background page can be applied to multiple pages, while a page supports only one background page.

To replace the background page of a page, you can replace it under 3D Background > Apply Page Background or select other background page under Page > Background.

Setting Current Page Effect

You need to set the current page effect for each page separately, and the effects do not affect each other. The viewing angle, model, data and animation of the 3D component can be referenced from the background page.

Note:

Before that, you need to set the 3D scene, data layer and model animation in the background page.

For details about the 3D component functionality, see FVS 3D City Scene Component and FVS Custom 3D Scene Component.

The following table describes these settings.

1. You can use getWidgetByName to get the 3D component in the background page, but if there are components with the same name in the page and in the background page, the component in the page will be returned.

2. The click event of the hidden layer in the old template cannot be triggered after the upgrade and needs to be manually adjusted.

3. Assume that there is empty content in the dataset fields bound by data labels. Before the upgrade, data labels with empty data content are not displayed; after the upgrade, an empty label is displayed, requiring manual adjustment of the data.  

4. If there is ticked content in data labels but not in the data warning of the old template, after the upgrade, the data warning displays an empty label, requiring manual adjustment.
