Problem with Pix4d mesh and point cloud when loaded in ION

CesiumJS
1

Hi,
I exported mesh (.obj, .fbx), point cloud(.laz) of a tower in pix4d, when I try to load them in ION for visualization, the orientation and location is always distorted and I have to manually adjust the mesh and point cloud. I am unable to fix this issue. For future work I want to automate the uploading and displaying data.
Please help.
Thank you

Welcome to the Cesium Community!

I’m sorry that you are experiencing this issue with your point cloud data. Are you able to send the asset id of your point cloud in ion to support@cesium.com? We can further look into the issue and see what is causing the orientation and location distortions.

Thank you very much for the response. The problem is occurring when I try to load .fbx or .obj (mesh) as 3D Model (tile as 3D Tiles or gltf). The orientation and geolocation problem is solved when I load it as 3D capture.

Hi, did you have the solution regarding this issue? I have similar issue with this while uploading my .obj file exported from pix4d to cesium/teria JS.

Best regards,

Hi,

There is generic support for these formats, so we need to be able to take a look at the resource in order to help you further, otherwise we’re just guessing at random and wasting time. Either an Ion asset ID, or a file, or a URL, or something.

Cheers,

Alex

Hi Alexander,

Thank you for your suggestion. Following up on your advice, so does it mean I have to send my .obj data to support@cesium.com in order to solve my issue?
Thank you.

Cheers,
Anom

Hello Anom,

The easiest way to send us your data is to upload it to Cesium ion and send us the asset ID. We can retrieve it using that—even if tiling is unsuccessful.

Alternatively, you may use a file-transfer service of your choice (e.g., Drive, WeTransfer), and post the link either in the forum or in an email to support@cesium.com.

We received your email to support@cesium.com. Can you please send us the .fbx and/or the .obj via one of the methods described above? We can investigate and continue the discussion here.

Thank you,
Matt
