Deformation Envelope LPE
This Project is part of a student project from Ecole Centrale de Lyon.
See this Mock-up for immediate understanding.
Main points are :
- a. envelope effect (math)
Lib2geom provides good mesh-deformation. The toy "mesh-grad" is a good example.
- b. envelope parameter UI (how to handle the control of the envelope)
The envelope may be a single path. But there are particular nodes : the first four ones. Johan: the sodipodi:nodetype attribute of a path determines the nodetype. you could add a new nodetype to specify the 4 special corner nodes. This way you can reuse all node-editing stuff that is already present in inkscape, with only tiny changes needed. Just having it as one (closed) path is nice, good idea!
