Dear all
I'm working on a project to visualize a tiled textured 3D model in a webbrowser using the exported COLLADA tiled model from Agisoft PhotoScan. I'm planning to use the XML-file with the tile-attributes (x-min, x-max...) to create/fill a tree element in Javascript.
However, I've encountered some irregularities in the output of Agisoft PhotoScan that I do not understand.
In the tile structure of Agisoft PhotoScan every parent tile is split in 8 children. When there is no data/mesh/model in a spesific child, no child is generated. As such it is possible that a node has only 4 children. In this case, these 'empty childs' are not included in the XML-file nor their is a mesh created.
However, there are sometimes 'empty tiles' included in the XML file. This means that the attributes (x-min, x-max...) are included, but no mesh is included. These empty tiles have one to several children. This means that there are data available.
I cannot find any logic explanation nor logic structure in the missing data.
Does anyone have similar experiences? Or an explanation for this strange phenomenon?
