3DTiles modelMatrix bug?

Hi All

I am using cesium loading 3dtiles data,Add modelmatrix option and debug. It seems that modelmatrix does not affect BoundingBox.

Cesium version :1.56

operation system: w7 sp1

Chrome: 66.0.3359.181

This problem does not occur if I use bentley’s data. Is this problem caused by using BoundingBox different BoundingSphere?

Hey xuncanzhe,

Can you put together a Sandcastle example showing this problem? It’d help to be able to reproduce it so I can figure out if it’s a problem with Cesium, or with the data etc.

If the tileset is using “region” bounding volumes then it is most likely this bug: https://github.com/AnalyticalGraphicsInc/cesium/issues/5984

Thank you for your reply, It looks like the same situation.

Thank you for your reply, I have already seen similar issues in Cesium. It is caused by modelmatrix not converting the region.

Yup. I just opened a pull request to fix this here: https://github.com/AnalyticalGraphicsInc/cesium/pull/6755.

Hey all,

The issue at #5984 has just been closed and may resolve your issue. Look for the change in the Cesium 1.48 release on August 1st, or get it now in the master branch on GitHub https://github.com/AnalyticalGraphicsInc/cesium.
