Problema: Non sono riuscito a capire perchè (*di)->C()=vcg::Color4b::Blue; (come le funzioni vcg::tri::UpdateColor)
|

non funziona se prima non applico un filtro di tipo Colorize che modifica il colore delle facce
|
||||
(triangle intersection, triangle qualitity, etc...). Ritorno in getRequest MM_FACECOLOR, per sicurezza ho
|
||||
provato anche con MM_ALL.
|
||||
La stessa cosa succede se provo a cambiare il colore dei vertici,
|
||||
prima devo applicare un filtro che modifica il colore dei vertici (come ad esempio Border).
|
||||
Ho letto più volte il plugin meshcolorize senza trovare soluzione, ho provato con il debugger
|
||||
a guardare cosa succede ma sono solo riuscito a vedere che il colore della faccia viene effettivamente modificato.
