The complexity of models that users build with 3DTin is growing day by day. When working on very detailed models with closely packed geometries – like the one pictured below, it is essential that you should be able to select the exact geometry that you are pointing to.
However with the mouse picking algorithm we had employed so far, this task wasn’t accurate. Sometimes certain geometries would create an invisible cloud over other geometries that would prevent you from selecting the other geometry even though you point at it using mouse. It was pretty annoying. But it has been fixed now.
Now we have implemented a well known WebGL based mouse picking technique to detect the exact geometry you are pointing at. This will make the modeling experience more pleasant going forward.
More improvements coming soon. Stay tuned.
