I have a ContextCapture generated 3d-tiles that looks great and smooth in Cesium.
Then I use ContextCapture to generate obj models of the same scene and convert obj to b3dm myself by using obj2gltf and gltf-pipeline.
However, my self generated 3d-tiles is not as smooth as the one ContextCapture generated.
You can see from the pictures below, the upper one is the 3d-tiles I generated, it looks like many triangles.
The ContextCapture-generated one of the scene is below, and it looks smooth.
I wonder why this happened?
Any help appreciated.
