3 years ago This is solved for now with pg2b3dm 1.3.3 (https://github.com/tudelft3d/pg2b3dm/tree/1.3.3). The bounding volumes now contain the full extent of the tiles rather than the extent of the centroids. The z-transform is removed since 3DTilesRendererJS doesn't use it when visualising the tiles, so a hack was used before in the viewer, which shifted the tiles with the z-transform but not the bounding volumes.
The size of the bounding volume of the root tile is now increased with the (original) z-transform, since removing the z-transform from the tileset would make it necessary to change the z-position of the root bounding volume, but this would give a problem in the viewer again, about which we will open an discussion/issue at 3DTilesRendererJS. But strictly seen, the tileset is already valid as it is now.
The boundingVolumes (x,y) correspond with the extent of the centroids of the buildings which is wrong. And there's a problem with the z as can be seen in de debug mode of 3DTilesRendererJS.
