Oi Tiago Há uns tempos fui ao teu site para ver o que andavas a fazer mas estava em baixo. Sempre foste para a Austrália?
Eu tou pela Illusive mas cheio de vontade de bazar para algum lado mais interessante. No processo também pensei no que sugeriste de usar geomatria, NURBS, para calcular os weights mas acabei por me ficar pelo mais simples. Pah eu tento sempre implementar ideias que tenho e no Softimage o caixote de ferramentas é consideravelmente maior e mais interessante. Ainda me lembro quando me falaste pra mudar pra XSI ;) Cumps Pedro Alpiarça dos Santos On Tue, Jan 21, 2014 at 5:00 PM, Tiago Craft <craft....@gmail.com> wrote: > Cool. > One interesting solution too would be to use meshes instead of nulls. we > used that in production and it worked quite nice for body parts, but it > surely lacked the speed and procedural behaviour of your solution, which > works better for face deformers. > > Heat algorithms tend to be very usefull too, in situations where the mesh > folds a lot. > > > ( hey Pedro!! que fixe que continuas cheio de ideias :) ) > > > 2014/1/21 Marco Peixoto <mpe...@gmail.com> > >> Interesting, tks for sharing Pedro >> >> >> On Tue, Jan 21, 2014 at 12:06 AM, pedro santos <probi...@gmail.com>wrote: >> >>> This was the solution I came up with.
