A powerful idea that has been planned for a long time is that of procedurally adding editing handles to the 3D scene that allow manipulation of Entity parameters in much more intuitive and expedient ways. This might include:
- Resize/drag handles on the outside edges of a bounds - e.g. more precise control over size/shape
- Add/delete/move nodes on a spline or polygon - e.g. change the outline of a building
- Increase/decrease quantities - e.g. quantity of books on a shelf
- Add/remove/edit modifiers and influence points - e.g. holes in a wall
- Adjust UV offset and scale - e.g. texture mapping of floor surface
- Select from a set of options - e.g. switch theme or styling of material or meshes used
This has the potential to hugely increase accessibility to people using procedural content in their scenes.
