Interactive previews of 3D models_user

censhare Web renders interactive previews of 3D models. View the models in 360° panoramas and explore their environment.

Context

The Preview is available on the Overview tab of a 3D model asset page in censhare Web.

Prerequisites

• An Assigned preview widget and a properly configured Preview widget on the 3D model asset type page is required. Your administrator takes care of this.

• Interactive 3D model previews are currently supported with censhare Web in the Google Chrome browser.

Introduction

For 3D model files, censhare Web renders interactive previews for the most common and relevant file formats. See supported formats. For these file formats, you can move and rotate an object to view it from different positions or zoom into it to view it in different sizes. You can adjust the background. You can display the wireframe model.

For other file formats, more basic preview options are available. You can rotate a model and view it in a separate browser tab.

You can access the available preview options from the toolbar of the Preview widget.

Upload 3D model files

To upload a 3D model file or 3D model ZIP file, drag-and-drop the file to any drop zone in censhare Web.

In most cases, censhare recogonizes the MIME type automatically and stores the file as a 3D model asset in censhare. The interactive preview is then available by default.

Prepare zipped 3D model files for preview

Some 3D model files are stored in ZIP files. The ZIP file contains the actual 3D model file (the wireframe), and additional texture and color information in separate files. If the interactive preview is not rendered automatically after upload, do the following:

1. Open the asset that is created after you upload the ZIP file.

2. On the Details tab of the asset page, edit the Status properties: In the Type field, select 3D model and click OK. 

The preview of the 3D model displays on the Overview tab.

Preview actions
