This article serves as a troubleshooter for cases when an output is missing from the 2D/3D view or when a functionality is not enabled on PIX4Dcloud / PIX4Dcloud Advanced.
IN THIS ARTICLE
The missing output is:
Orthomosaic and/or DSM
Index Map (NDVI)
Point cloud
3D Textured Mesh
The unavailable functionality is:
3D view
Project view
Virtual inspector
Elevation profile
Volume calculation
Timeline / Cannot add a dataset to a site
Orthomosaic and/or DSM
Error description |
Cause / How to solve |
---|---|
After uploading from PIX4Dmapper for processing, the Orthomosaic and/or DSM are not displayed in the 2D view. In the Files > Results section the DSM and/or Orthomosaic show the EMPTY status. |
The correct output format was not selected before uploading. 1. In PIX4Dmapper, re-open the project. On the menu bar, click Process > Processing Options... |
The Orthomosaic and/or DSM are not displayed in the 2D view. The Orthomosaic layer has a warning message "This layer can't be displayed". In the Files > Results section, the Orthomosaic and/or DSM show the PROCESSED status. They can be considered having a significant size and/or a complex geometry. |
This error is expected for outputs having a significant size and/or a complex geometry. In this case, the tiling process failed, meaning that the generated 2D output could not be split into smaller web maps (tiles) for several zoom levels and, for this reason, the output cannot be displayed. The output has been generated and indeed it can be downloaded from the Results page, but the file is too big to be displayed on the 2D view of PIX4Dcloud. So far, these are the variables that seem to be impacting the tile generation speed:
Some proposed solutions:
There is no precise file dimension that prevents the failure of the tiling process as this depends on different factors among which the number of the images, the image content and texture, the complexity of the geometry of the model, the geographic transformations, etc.. |
Index Map (NDVI)
Error description |
Cause / How to solve |
---|---|
After uploading from PIX4Dmapper for processing, the NDVI is not displayed in the 2D view. In the Files > Results section the NDVI shows the EMPTY status. |
The correct output format was not selected before uploading. 1. In PIX4Dmapper, re-open the project. On the menu bar, click Process > Processing Options... |
Point cloud
Error description |
Cause / How to solve |
---|---|
After uploading from PIX4Dmapper for processing, the Point Cloud is not displayed in the 3D view. In the Files > Results section the Point Cloud shows the EMPTY status. |
The correct output format was not selected before uploading. 1. In PIX4Dmapper, re-open the project. On the menu bar, click Process > Processing Options... |
After uploading the file as a result, the Point Cloud is partially displayed. Multiple LAS tile files were generated locally and uploaded. |
Only one LAS file can be uploaded as a result to PIX4Dcloud. What is happening is that PIX4Dcloud is only able to load one file at a time, so it's choosing to display one tile only. Check How to merge the Tiles of the Point Cloud to merge the tiles that were created in PIX4Dmapper and then upload the merged LAS file or use some third-party software to merge the tiles. |
3D Textured Mesh
Error description |
Cause / How to solve |
---|---|
After uploading from PIX4Dmapper for processing, the 3D Textured Mesh is not displayed in the 3D view. In the Files > Results section the Mesh OBJ shows the EMPTY status. |
The correct output format was not selected before uploading. 1. In PIX4Dmapper, re-open the project. On the menu bar, click Process > Processing Options... |
The 3D view doesn't render the Mesh file and the OBJ 3D Textured Mesh exceeds 1 GB. |
PIX4Dcloud supports visualizing OBJ Mesh files that are smaller than 1 GB. Ensure that the OBJ 3D Textured Mesh is smaller than 1 GB before uploading it to PIX4Dcloud. |
The 3D view doesn't render the Mesh file and the JPG Texture file exceeds 16384 x 16384 pixels. |
PIX4Dcloud supports 3D Textured Mesh files having a JPG texture image that is at maximum 16384 x 16384 pixels. Please ensure that your JPG Texture file is smaller than this size before uploading it to PIX4Dcloud. |
3D view
Error description |
Cause / How to solve |
---|---|
The Point Cloud and 3D Textured Mesh are uploaded as results and the 3D view has visualization issues. |
The issue is due to the merged viewer/editor that displays the non-georeferenced 3D Mesh and the georeferenced Point Cloud together. The mesh (.obj, .jpg and .mtl) uploaded as a result to the Cloud is indeed not georeferenced. However, there is an option for georeferencing the uploaded mesh: 1. In the project, go to Files > Results. |
The 3D view doesn't render. |
It is necessary that the web browser application supports optimized WebGL for rendering 3D graphics. This is a known issue for some iOS devices. For more information: ArcGIS help, Sketchfab help. |
Project view
Error description |
Cause / How to solve |
---|---|
The project files were uploaded from PIX4Dmapper without selecting Start processing. Then, from the Files > Results section of the project, the results were uploaded. The project status is UPLOADED, the UI contains no layers. |
In this way PIX4Dcloud receives both the images and the p4d file for the (photogrammetric) processing but also the results that need to be web-optimized to be displayed. The result of this workflow is that the status of the project is stuck because the app is not able to decide whether it should start processing the images or the results. If the goal is to upload the results without any processing, the p4d file and the images are of no use and should not be uploaded to PIX4Dcloud. Upload the results creating a new dataset, as explained here. |
The project files were uploaded from PIX4Dmapper for processing. The project status is PROCESSED, the UI contains no layers. |
The correct output format and/or the necessary step was not selected before uploading. See the related sections: |
Virtual inspector
Elevation profile
Error description |
Cause / How to solve |
---|---|
The elevation profile is missing / doesn't work |
One of these might be the reason:
|
Volume calculation
Error description |
Cause / How to solve |
---|---|
There is an error calculating the volume |
The occurrence of one of the following conditions prevents the volumes from being calculated:
|
Timeline / Cannot add a dataset to a site
Error description |
Cause / How to solve |
---|---|
The timeline is not displayed at the top of the project / I cannot add a CAD overlay / I cannot add a dataset from inside my project |
The dataset is not assigned to a site yet. Assign the dataset to a site first. Then, the timeline and the Add dataset option will appear in the project view. |
