Hey! many thanks! i tried the option to export it into an obj file an then to a pshape, but its to slow and gets errors like “java.lang.RuntimeException: java.lang.OutOfMemoryError: GC overhead limit exceeded” So i think the best option is to use your function toxicToPShapeSmooth but, as your functions that you implemented in java, i don’t know how to use the List or Collection in processing, i was trying to change it for something like arrayList but without success. i’ll be trying that
