Outputs are not displayed in the cloud 2D or 3D view

The following cases can happen after uploading a project from the desktop and processing on the cloud:

  • 2D map view: Empty, only the base map is shown, the orthomosaic and/or the digital surface model (DSM) are not displayed.
  • 3D model view: Empty, the textured mesh is not displayed.

A typical cause is related to settings that were selected in Pix4D desktop beforehand. Pix4D cloud servers process images based on the project file (.p4d) that is uploaded. Therefore, solutions to output display issues require to:

1. Re-open the project with Pix4D desktop.
2. Change the processing options accordingly as detailed below.
3. Re-upload to Pix4D cloud for re-processing.

GeoTIFF Raster DSM and GeoTIFF Orthomosaic outputs are selected. 1. On the menu bar, click Process > Processing Options...
2. Select the processing step 3. DSM, Orthomosaic and Index.
3. Select the tab DSM and Orthomosaic.
4. Check the two GeoTIFF boxes. The Merge Tiles box does not matter.

2. Select the processing step 3. DSM, Orthomosaic and Index.
3. Select the tab Index Calculator.
4. Check the GeoTIFF box. The Merge Tiles box does not matter.
5. Check the box of the NDVI formula.

OBJ 3D Textured Mesh output is selected. 1. On the menu bar, click Process > Processing Options...
2. Select the processing step 2. Point Cloud and Mesh.
3. Select the tab 3D Textured Mesh.
4. Check the OBJ box.

Additional causes can prevent the outputs from being loaded and affect the display.

ISSUE
EXPLANATION
General
Outputs have a significant size and/or a complex geometry. The cloud viewer can be limited by browser resources (display, memory) because of the input images (number, resolution, content) and project properties (geolocation information, extracted keypoints, resolution settings). For more information: 204191535.
The web browser application does not support 3D visualization. It is necessary that the web application supports optimized WebGL for rendering 3D graphics. This is a known issue for some iOS devices. Note that only Internet Explorer 11 and Edge are supported. For more information: ArcGIS help, Sketchfab help.
Project fails to be processed on the servers. Several leads are recommended to be explored to troubleshoot the problem. For more information: 203694199.
2D map view
Images are captured with a multi-spectral camera. One GeoTIFF file is generated per band instead of the single true color orthomosaic. The cloud platform only displays the DSM and NDVI outputs. However, all GeoTIFF files are downloadable. For more information: 115000707003.
