Error loading mesh on tile-3d

[quannh997]

Hi!

I have tried load Tile3DLayer with both type loader I3SLoader, Tiles3dLoader for my region but they have same issue is tile have crack like earthquake and quality mesh is so bad. I think maybe reason is my server but when i tried data i3s on arcgis server, arcgis scene is showing data is good, but i loaded this scene on loader code example the issues still happend. ArcGis Scene: In code example

The data i use here: "https://tiles.arcgis.com/tiles/6isf2oKhmeNEAK04/arcgis/rest/services/TextureMesh_v17/SceneServer/layers/0"

Can explain for me how and why i can handle that thing?

Looks like precision issue we fixed recently. You need do use LNGLAT_OFFSETS coordinate system like here in example: https://github.com/visgl/loaders.gl/blob/5bf1db80e532cde86b92dcbaee50696632e94d7b/examples/website/i3s/app.js#L241

it not work for me, the problem is when i use LNGLAT_OFFSETS, tiles doesn't shown up. But coordinateSystem is METER_OFFSETS or IDENTITY, i3s show normaly but the errors still theres, nothing change.

I need to check. I need token for your layer example

Solve the problem when upgrade @loaders.gl to alpha 4.5 and deck.gl to 8.7.0-alpha 11. I have another question, I try to test data on type i3s and b3dm, the tile-3d-loader can clear tile loaded in memory, so memory used is between 1-2 gb max. but with i3s-loader, tile loaded in memory is stack-up, can't clear tile in out of the current view. Memory ascending to 3 gb. The problem is I want to use i3s type cause it convenient to process, the data is on local server, so if you want the data to test, I can provide. How can I clear the data saved in memory and keep only tile loading in view for the performance. Did it involve with compareDistanceToCamera and updateTileVisibility in Tileset3DTraverser.

Thanks!

loaders.gl 4.0.0-alpha is a breaking, currently very unstable branch that lacks a number of fixes from 3.1 track. I strongly recommend against using it.

Thanks for advice, i change to 3.1.6 stable, but still have another question for memory, any way to clear tile cache for i3sloader? For now or feature update.

We need your data set to check it there are memory leaks

I test with i3s 1.7 loaders.gl 3.1.7 with base map on harp.gl
