So, is ILoveSketch new? Perhaps, if I could understand what it does:
The system coherently integrates existing techniques of sketch-based interaction with a number of novel and enhanced features.
Or, "a as-natural-as-possible sketching system for creating 3D curve models." Features include:
- Automatic view rotation.
- Axis widget for sketch surface selection.
- Inferred changes between sketching techniques.
- Virtual sketchbook.
- Simplified 2D and 3D view navigation.
- Multi-stroke NURBS curve creation.
- Gesture vocabulary.
It's not clear whether we can download the software, but the Web page contains some sample files and a video.The video is well worth watching, nevertheless.
