- Simpler explanation of picking, but their actual code in the linked code is dumped in one gigantic, hard to read function. I think they were using only the default frame buffer.
I am halting work on this for now while I work on tree maps.
The user should be able to click on a superquadric in the scene and have the corresponding node be highlighted in the tree widget. We may want to have a special selection box (yellow colored) in the tree widget to denote this.
Having this feature will make it much easier to find superquadrics in the tree widget. It probably requires color picking.
