Doing the iWarp tool in paint tool way was rejected because it destroys the image very fast.

Once gegl is fully integrateed however, It can be a sort of an effect layer/op in the graph.

CAGE tool currently under development already creates a piece of such a tool, a displacement map renderer. In fact, in many ways, the cage tool and iWarp are alike. Once cage tool is done, spawning an iWarp tool form its code should be trivial. All you need is to replace the UI code to brush instead of polygon editor and create the displacement map. Render pipleine should already be in place. -- Alexia _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
